the advantages and disadvantages of different punch feeders - harsle punching division

The air feeder is the earliest feeding equipment used in the stamping industry. Its principle is to use air as power, clamp the material by the cylinder, and feed the material by the telescopic stroke of the cylinder, and adjust the length of the feed by adjusting the cylinder. The length is controlledby adjusting the stroke of the cylinder.

Advantages: easy to operate, easy to install, affordable, and can realize automatic punching feeding equipment at the lowest price. In actual production, it is mainly used to feed stamping products that require low accuracy and low speed.

The roller feeder is currently the most widely used feeding equipment. Its principle is to connect to the output shaft of the punch through a connecting rod, which is driven by the punching press, and the feeder is adjusted by the deflection of the eccentric disk.

Advantages: the unique split cam mechanism and precision gear ensure high-precision and high-speed feeding. There is no need to adjust the feeding thickness, and the feeding distance can only be changed by gears. The relaxation device is an eccentric cam, so the relaxation angle can be adjusted freely within the range of 0180.

Thisis a model that uses a full set of the numerical control system to drive the feeding roller to realize the feeder. The feeding parameters (length, speed, quantity) can be set on the touch screen to complete a simple feeding length, and the feeding length is unlimited.

Advantages: servo feeding precision is high, multi-stage feeding, long stepping function, convenient operation and debugging, the high degree of customization (various thick plates, swing type), especially suitable for precision machining occasions

Driven by a cam, using a cambered cam and 3 plate-shaped cams to achieve high-speed and stable feeding. A built-in detection mechanism can detect blockage or deformation of materials. The feeding interval angle of 165 degrees makes the material stay longer in the punch. Combined with the mold guide pin, the release time of the material can be adjusted when guiding. Can transport round or square wire.

Advantages: The feeding speed can be synchronized with the punching machine, and the fastest speed can reach 1200 times/min. Its feeding accuracy is higher, more stable, and the machine is lighter and smaller. It is suitable for feeding ultra-thin materials, such as connection High-precision and high-speed stamping of detectors, lead frames, and inspection parts.

top 10 advantages for metal punches and die - whiteout press

Today punch and die accomplish more than just punching holes. They are able to complete numerous processes on the same machine, such as forming, tapping holes, extruding, ribbing, removing burrs from the parts and so on. Punch and die manufacturers understand the need for having the flexibility to complete multiple processes. Therefore to stay competitive, they design and build metal punch and dies which could virtually eliminate time-consuming secondary operations. Well, here are 10 advantages of metal punches and dies.

Initially, punching technology featured a single tool with a corresponding die. It required a certain die clearance to force its way through the material to make a hole or certain geometric shape. Gradually the designs evolved wherein material processing was accomplished by tracing a template pattern, a great improvement over files and shears. The new techniques allow a part to be processed faster, more accurate and consistent than previously used methods.

Computer designed metal punches and die created the ability to control toll hit positions numerically. Punch and die manufactures found ways to automatically change tools, rotate them and control the position with the CNC punch machines. Todays metal punches and dies have great axis speeds and punching hit rates.

The design of metal punches and die are generally very safe to use. With proper clearance between the punch and die the slug is removed and this ensures that the tooling lasts longer. And such tooling is reliable and safe to operate.

The punching tool is not limited to one type of material. Punch and die manufacturers use metal punches and die to process a variety of materials. Some of the basic materials are stainless steel, steel and aluminum plastic, ceramic and so on.

The components created by a metal punch and die can be seen in all areas of life: transport systems such as trains, automobiles, trucks, trailers, lawn, and tractor equipment. You could also find them in exercise equipment, lamps, lighting, and indoor furniture and construction materials.

One of the most difficult materials to punch is stainless steel, especially where the strength of the part is essential for a particular application. Due to higher tensile strength, tapped holes are often found in them. Since this material is immune to rust and could be readily sanitized, it is the most sought out metal by the food service industry and medical industry. Despite the heavy demand, the metal punch and die process are able to create all the products that are required.

Metal punches and die could save a tremendous amount of labor costs. This tooling is generally paired with a corresponding feeding device. Also, automated production ensures that the parts are produced with minimum labor cost.

In certain operations such as progressive stamping, a major portion of the metal sheet is used up in the process. The punch and die stamping tool could include processes involving coining, punching, bending and shaping the product in the desired way. Such processes reduce or even eliminate scrap and increase production. This again aids in reducing the manufacturing cost.

Metal punches and dies are designed with a hard material to ensure the production is of high volume without die degradation. In other words, the metal punches and die can create more parts of good quality and reduce the ratio of failed parts.

Efficient punch and die manufacturers ensure that their metal punches and die to provide the lowest cycle times per part. Longer runs ensure that the parts are produced in a shorter time. Punch and die manufacturers also ensure that their metal punch and die designs are long lasting. These are the advantages of metal punches and die.

the advantages and disadvantages of compression molding? - mdc mould

Compression molding (also called compression moulding) is a method in which powdery, granular or fibrous plastic is first put into the mold cavity at the molding temperature, and then the mold is closed and pressurized to form and solidify it. Molding can also be used for thermosetting plastics, thermoplastic plastics and rubber materials. Compression Moulding is widely used in industry, agriculture, transportation, electricity, chemical industry, construction, machinery and other fields. As a China compression mold supplier, MDC combines more than 20 years of compression molding experience with the latest compression molding technology to benefit our customers. MDC also fully understands that what are the advantages and disadvantages of compression molding.

Advantages of compression molding: (1)The loss of raw materials is small and will not cause too much loss (usually 2%~5% of the product quality). (2)The internal stress of the product is very low, the warping deformation is also very small, and the mechanical properties are relatively stable. (3)The wear of the mold cavity is very small and the maintenance cost of the mold is low. (4)The cost of the molding equipment is lower, the mold structure is simpler, multiple cavities can be produced at lower cost, and the manufacturing cost is usually lower than that of the injection mold. (5)It can be used to form large flat products. The size of products that can be molded by mold pressing is determined by the mold clamping force of the mold pressing machine and the size of the mold plate. (6)Molds with a large number of cavities can be placed on a certain template to improve productivity. Automatic production can be realized through automatic feeding and automatic taking out of products. (7)This can form a uniform part without any trace. The surface is smooth without secondary modification. The product has high dimensional accuracy and small shrinkage. (8)It can be produced in batch with relatively low price.

Disadvantages of compression molding: (1)The whole molding cycle is long and the efficiency is low. The time required to start and repeat the operation sequence is between 1-6 minutes. (2)At present, it is not suitable for molding complex products with depressions, side slopes or small holes. (3)When burrs occur, they must be trimmed manually, which will not only reduce productivity, but also increase labor costs and material waste. (4)The disadvantages of compression molding are that the mold manufacturing is complicated, the investment is large, and the compression machine is limited, which is most suitable for mass production of small and medium composite products. (5)For thermosetting plastics, when the molded products have slight defects, they are often unable to be recycled, which requires high mold surface and material filling requirements.

folders or press brakes? how to choose

When it comes to bending, many fabricators just buy press brakes. A hydraulic press brake can be a great option for any shop as these machines are known for power and versatility.Press brakes are generally easy to setup to make a few quick bends on, but metal folding machines are becoming increasingly popular with fabricators as both their capabilities and capacities have increased over the years and in some tasks they are just better suited for the job.

First off let's assume you know what a press brake is already and how it works in the forming of sheet metals. But, if you need help you can read this article covering press brakes in detail.Understanding that process (press brakes) makes understanding the benefits and advantages of a folder that much easier.

A folder can be referred to by a variety of different names. Sometimes they are simply called a brake referring to the process of braking metal (note the correct spelling for the process is B-R-A-K-E, not B-R-E-A-K as one might easily assume). At other times, the term leaf brake is usedwhich refers to the clamping leaf and swinging leaf.

The folder is a machine that allows the sheet of material to rest on a table at the rear of the machine with only the flange (or material being bent) to protrude through the front of the machine between an upper clamping beam, the table itself and a moveable swing beam. The material is then clamped into position with a small percentage of it protruding beyond the table and the swing beam folds the material to the desired angle

Other variations of the folder are often referred to as a box & pan brake.It's important to know the difference between these two variations of a folding machine as one utilizes a straight, non-removable clamping beam and the other utilizes tooling on the clamping beam that allow for a material to be formed with side flanges as shown here:

If your parts have names like panel, cover, door, or pan, then a folder is likely for you. Folders are just better-suited to make cover panels, pans, and doors than a press brake would be. If your manufacturing has fabricated parts that are of thin material, long lengths (10-12), wide (4-6) and have short flanges, then they are very well suited for a folding machine.The material will be easier to handle and manipulate as it stays flat on the bed and gauging surface and is brought forward only the amount necessary to be bent

A folders bed keeps the material flat as it bends. Long sheet metal wont travel toward an operators face, require two operators (or lifting devices), or risk the possibility of simply the materials own weight back bending it. As a result, bending large pieces of thin material is much more manageable on a folder.

If youre making panels, trays, covers, and other parts that have generally short flanges over wide or long areas and use thin material, you're likely a great candidate for a folding machine in lieu of a press brake. If your parts are small and require complex bends that can easily be handled by one operator, then youre better off sticking with a press brake. Either way, at Southern Fab, we can help you make the right choice for your needs and budget.Call us today at 813-444-4555 or visit us on the web at www.southernfabsales.com.

advantages and disadvantages of mechanical and hydraulic presses | fangze machinery

Mechanical press is a forging machine driven by a crank link or toggle lever mechanism, cam mechanism, and screw mechanism. It is a machine tool for pressure processing of materials. It is processed by applying strong pressure on the blank to deform and break it. Components.

Compared with mechanical transmission, hydraulic transmission has many technical advantages such as large power-to-mass ratio, convenient stepless speed regulation and overload protection, and flexible and convenient layout.

1. The hydraulic press uses a hydraulic pump to generate power through the control circuit hydraulic actuator to transmit power. The liquid meson has water and emulsion; hydraulic oil. It is characterized by high working pressure, stable operation, free control of working stroke, large adjustment range, large working space, and moderate working efficiency. It can complete most of the work of mechanical press machine and has a wide range of applications. The configuration of the hydraulic press is more complicated. The larger presses are generally equipped with independent pumping stations, the control parts and circuits are more complicated, and the cost is relatively high.

2. From the perspective of the mold, the hydraulic press is suitable for large, complex and precise automotive sheet metal parts, especially with a stretch function. Suitable for large cover parts and door parts of automobiles. Its characteristics are relatively dense compared to mechanical presses, and the stability of product structure and size is better. Maintenance is more convenient than mechanical presses, because of the standardization of hydraulic parts, the maturity of the theory is very high. For example, to find faults, you can draw wings from a hydraulic schematic diagram. Just insist on using genuine hydraulic oil.

3. The crank-arm press uses the crank arm to transmit force, which is characterized by fast running speed and high working efficiency, and the working stroke is fixed and cannot be adjusted. It is strictly forbidden to overload operation. Generally used for blanking, punching, stretch forming, etc.

The friction screw pressesuse the wheel to drive the friction wheel to transmit the force by the inertia rotating screw, which is characterized in that it is not restricted in the effective working area of the screw, the transmission pressure is large, and the work efficiency is moderate. The operation is not easy to control. Generally used for material correction; simple molding; die-casting cavity molding. Shuangdong press is mainly used for stretch forming. It relies on the screw to transmit force directly.

Mechanical press 1. fast operation, high efficiency, low cost, simple control part, easy maintenance; 2. small work surface, generally equipped with counterweight wheels (flywheels) to increase its transmission power Noise and vibration.

Compared with mechanical transmission, hydraulic transmission has a large power / mass ratio, which is convenient for stepless speed regulation and overload protection, flexible and convenient layout and other technical advantages. Mechanical presses are fast, but their strength is not as large as hydraulic presses. Hydraulic presses are heavy but slow.

economic effects of machinery: advantages and disadvantages

This is the age of machinery. Machines have become a part and parcel of modern life. They are used in factories, offices, houses, construction, transportation, communications, power, etc. They have revolutioned the methods of production and increased productivity, production and income, thereby leading to a rapid economic growth.

At the same time, machines have brought monotony in work, evils of the factory system, class conflicts, unequal distribution of wealth and income, etc. We discuss the economic effects of machinery as under.

Machines help in the exploitation of natural resources for the benefit of the people. Natural wealth of rivers, forests, minerals, land, mountains, seas, etc., can be properly exploited and used for productive purposes with machines.

The use of machines helps in increasing the production of capital goods, durable consumer goods, and agricultural products. Perishable consumer goods like milk, vegetables, fruits, eggs, etc. are no longer perishable and are available all the year round with the spread of cold storage facilities. This prevents their wastages and prices from rising when their supplies are short. By increasing production, machines raise the incomes of the people and the country.

Machines provide a variety of consumer goods like TV, car, refrigerator, washing machine, household gadgets, etc. which make life comfortable and increase the standard of living of the people. The manufacture of innumerable consumer goods from the smallest pin to the largest aeroplane has been made possible by machines. Machines have, in turn, been manufactured by other machines, called capital goods.

The use of machines helps the producer in many ways which tends to increase his production and income. It leads to large scale production, division of labour and specialisation. These, in turn, increase production, reduce costs and raise profits. Machines save time and labour. They work faster than man. For example, a person operating a computer or a tractor finishes his work faster than many persons engaged in doing the same work by hands. Thus machines increase the productivity of labour and hence production.

Machines help the worker in performing his duties in a better way than by hands. The efficiency of the worker increases because he can work accurately and faster, and produce quality products in larger quantities. Jobs which are dirty dull and involve lifting of heavy loads are done by machines. For example, the cleaning of the city and the sewerage system by machines, preparing of accounts by a computer, and lifting of heavy loads by a crane have brought relief to workers. They take more interest in their work and their efficiency increases.

In the beginning, machinery replaces labour and there is unemployment. But in the long-run, it creates employment. The use of machines increases productivity of labour thereby increasing production, reducing costs and making the goods cheaper. As a result, their demand increases. In order to meet this demand, more workers are employed to increase their production. Income will rise which will further increase the demand for goods, thereby necessitating the employment of more workers.

This process will continue in a multiplier way. Secondly, as machines are made by machines, workers are needed to manufacture new machines. Thirdly, after some use, machines need maintenance, repairs and replacement.

For manufacturing their spare parts, and for repairs and maintenance, machines also need men. Fourthly, machines require for their operations, repairs and maintenance, educated and skilled manpower. This leads to the setting up of institutions on formal and technical education which create demand for the teaching staff. Lastly, educated and skilled workers invent new machines and innovate new processes, thereby opening more employment opportunities. Thus machines create more employment.

By increasing the productivity of all factors of production like land, labour, capital, etc.. machines raise the overall production in the economy. It leads to the development of the industrial, agricultural, tertiary and export sectors of the economy. Consequently, employment, national income and growth rate of the economy increase.

Working on the same machine makes the work of a worker monotonous. There is no joy and satisfaction for him because he performs the same work over the years. This tends to reduce his efficiency. If the worker wants to migrate to some other place, it is difficult for him to find the same job in which he specialises. Thus machinery reduces the mobility of labour.

The use of machinery leads to the development of the factory system and the evils associated with it. There is exploitation of men, women and children. Trade unions emerge which lead to class conflicts. The factory system gives rise to urbanisation with its bad effects like congestion, pollution, slums, dislocation of family life, diseases, etc.

Machinery adversely affects the economy in a number of ways: (a) Class conflicts lead to strikes and lockouts. They reduce production of goods and their prices rise, (b) Inequalities of income and wealth increase because profits rise rapidly than the rise in wages, (c) Often goods are produced in anticipation of demand, thereby leading to over production of goods. This leads to recession in the economy, (d) As machines replace men, there is unemployment in the country. But this is only in the short period.

5 key advantages of using cnc machinery in manufacturing | pacific research

Computer Numerical Control (CNC) machinery is growing more popular, and its easy to see why. This high-tech manufacturing method removes many of the barriers that prevent designers from creating the products of their dreams. One of the greatest advantages of using CNC machinery is that you can build very complex components with a high degree of accuracy that simply isnt possible using conventional methods of the past.

A CNC machine uses specialized software to control cutting tools or other manufacturing instruments. To program the machine, a programmer or skilled engineer uploads a digital model of the component or product from a computer-aided design (CAD) system. Then, using a CNC coding language called G-Code, the programmer gives the machine detailed manufacturing instructions such as:

By comparison, conventional machinery is usually performed by a team of engineers or operators who directly oversee individual machines that perform specific tasks in stages. For example, a part may go through a mill, grinder, and lathe, each of which is operated by different specialists. Its a much more time-consuming and labor-intensive process. This is one of the main reasons why CNC machinery is playing a greater role in modern manufacturing. CNC machinery is a sleek, elegant solution to the most complex engineering and manufacturing challenges.

One of the main reasons why CNC machinery is so popular is because it enables product designers to create more complex components. These machines are especially useful for manufacturing parts with angles that are difficult to measure and cut manually. But there are many other advantages of using CNC machinery in the modern manufacturing industry, such as:

When you make a part or product by-hand or using conventional methods, you cant achieve the same degree of consistency and accuracy as you can using CNC machinery. CNC machines use design software, detailed model references, and fine-tuned precision tools to produce and replicate multiple parts that are virtually identical (with an average variation of less than 0.020mmsometimes as little as 0.003mm). Even the most advanced conventional machines cant duplicate these results.

This means that youll get an extremely uniform end product. In industries where high uniformity matters (such as the automotive, aerospace, dentistry, and medical industries), this is a major advantage. Its also a must-have for companies building complex machines or electronics that require different parts to fit together perfectly. Any slight variation in size, shape, or texture could cause the final product to malfunction. With CNC machinery, you can make almost any object and replicate it over and overeven if its incredibly complex and detailed.

Unlike manual manufacturing or conventional machinery, which requires an engineer to operate or supervise the process, CNC machinery is a more hands-off method. Most CNC machines operate automatically without any direct input or control from engineers. The machine is ready to go as soon as it receives its instructions from the computer and the manufacturer supplies the raw materials. This means that you can fabricate parts much faster, as theres no manual labor or excessive downtime required. Some machines can even operate 24/7.

One of the advantages of using CNC machinery is that youll maximize resources at every stage of the product development process. In the early stages, you only need a skilled engineer or programmer to create a digital model of the design and program the machine. When its time to manufacture the product, the CNC machine is largely self-sufficient (but may be monitored by an operator). It can also be programmed to reduce waste and only use as much raw material as absolutely necessary.

Using fewer resources and labor also leads to cost savings. When you conserve your resources, you can either reinvest what you saved into manufacturing more parts or you can reduce the retail price of your end product to gain a competitive advantage and attract customers. And, when you outsource your product development to a full-service CNC machinery provider, youll also save on overhead costs. The manufacturer is responsible for purchasing software licenses and the machinery, repairing or replacing machines and cutting tools, and hiring staff to oversee the process. Youll only pay for the final results.

One final advantage of using CNC machinery is that it gives you more manufacturing options. You can start with a limited run of high-quality components. Later, if the demand for your product is high or you need to quickly scale up to corner the market, its very easy to fabricate more parts using a CNC machine. Moreover, the quality and consistency of your products remain exactly the same whether youre building just a few parts or thousands. You can decide exactly how many parts you need at any given moment and reduce excess inventory.

For most projects, the advantages of using CNC machinery are clear. If youre looking for a manufacturing method that can deliver top quality products quickly with a high degree of accuracy and precision, CNC machinery is the obvious choice. Its efficient, reliable, and cost-effective.

Its also the ideal choice for industries that demand consistent parts or products that must be completed by a strict deadline. For example, some industries that almost exclusively use CNC machinery for manufacturing are:

However, while there are many advantages of using CNC machinery, it isnt necessarily the right choice for every project. This method can be more expensive than other manufacturing options, depending on how complex your product is or how many parts you need to build. For instance, if you only need to manufacture a dozen simple universal parts, then advanced CNC machinery may be excessive. Rapid casting, 3D printing, and other small scale manufacturing methods are often better alternatives in this case.

To decide whether CNC machinery is right for your project, you should get in touch with an experienced team of manufacturing engineers who will walk you through the pros and cons of this system. They will take into consideration your manufacturing budget, the complexity of the part or product you want to make, how many units you need, and how fast youd like them built. With this custom, holistic approach, youll get the most out of the manufacturing process.

PRLs engineers have dozens of manufacturing options available to help you solve any challenge facing your product: CNC machining, custom tooling, 3D printing, thermoplastic molding, reverse engineering, and more. No matter what stage your product is currently at, we can create it and optimize it for manufacturing.

advantages and disadvantages of compression moulding - process industry forum

Articles Advantages and Disadvantages of Compression Moulding Advantages and Disadvantages of Compression Moulding Within this article, Martins Rubber explains what Compression moulding is and demonstrates some of the main advantages and disadvantages of producing a Compression mould and the overall Compression moulding process. Developed in the 1850s, Compression moulding was the original method for moulding rubber and is still ideal for manufacturing low to medium volumes of rubber products. It remains a useful moulding process for forming bulky parts. Martins Rubber has a wide range of Compression moulding machines, from 5 tonnes up to a 500 tonne press, with a maximum of a 1 square metre press area. Compression Moulding is a traditional technique that involves taking a rubber compound and making a pre-form that is in the shape of the end product, but is larger than the final shape. A combination of heat and pressure is then used to mould thermoset rubber or plastic resin into the desired shape. The rubber or resin material is shaped using a heated mould tool, and the clamping pressure of a press is used to force the flow of the material inside the tool. The thermoset characteristic of the material is instigated by this process and permanent chemical change referred to as Vulcanisationforrubber takes place, fixing the shape of the product. Once this vulcanisation process is complete, the mould is then opened and the part extracted and allowed to cool, maintaining the shape of the mould that produced it. It is important to note that the part has a tendency to shrink during cooling to arrive at its final size. When the press is opened, the tool can be split and the part de-moulded. This technique can be used to make a wide range of products, such as: wellington boots, machinery parts, seals, gaskets or even door stops and chair feet. This manufacturing process is capable of reproducing the same product a large number of times, but it is not necessarily suitable in all situations. Here are some of the advantages and disadvantages that relate to Compression moulding as a process, to help you decide if its right for you and your product. Advantages: Lower cost Tooling Given that the process does not involve an Injection or Transfer cycle, the tooling has less infrastructure requirements than tools designed for other moulding methods. There is little else needed in the way of additional features, other than the particular features of the cavity itself that will produce the moulded parts, which clearly have to replicate the detail required of the product. Tools can be made of aluminium or lower cost grades of steel which can reduce costs, although any tool must be capable of withstanding the considerable moulding pressures required. Good for small production runs The lower capital cost of manufacturing a mould tool, setting up a press and beginning to run production parts means that Compression moulding is the most cost effective method of making smaller runs of parts. There is of course a breakeven point at which the higher capital cost of an injection mould tool becomes viable due to the lower cost of the parts that it makes. Correct assessment of the cost / benefitpoint is a key consideration when developing the best production solution for a new product. No gates, sprues or runners This form of moulding does not use gates, sprues or runners which are tooling features that materials have to pass through in other methods of production before entering the mould cavity. These can consume extra material and therefore cost and can also detract from the cosmetic requirements of a part. Good for large parts This form of moulding is best suited to producing large parts that require a significant bulk of material to manufacture. Given that the material is directly loaded into the mould cavity, there is no limitation on the weight of part that can be made, other than the size of press and tonnage required, whereas Injection moulding presses are limited in the weight of part they can produce by the volume of the injection barrel that fills the mould. Disadvantages: Greater waste Compression moulding is not as precise a method of making a product as injection moulding, due to the fact that the mould cavity has to be overfilled to some degree to achieve the correct pressure to cure the part. It is also often necessary to push air out of the cavity using excess material in order to create a void-free part, which again increases wastage, whereas an injection mould is more precisely filled and the material inherently drives out the air as the cavityis filled. Waste thermoset rubber or plastic generally cannot be melted down and reused so the cost of the part must reflect this. Higher labour cost This production technique is fairly simple, however it requires more man power than a semi-automatic injection moulding process to run. The skill level is often proportionately higher, and for larger parts or tools, manual handling may become an issue. Slower process times Because the thermal conductivity of rubber and resin is relatively poor, bringing a blank of material up to curing temperature by contact with the hot surfaces of the mould takes time for larger parts, which limits the speed at which parts can be cured and de-moulded. On the other hand, Injection moulding shoots material into the mould that is already at a temperature just below curing, therefore the extra time required to begin cure once the press closes is drastically shorter. Depending on the size of a part, a typical cycle can take around ten minutes, whereas the equivalent cycle of injection moulding would take approximately five minutes to complete. This can make a significant difference when producing parts in higher volume, when production rate and part cost become the priority. Not suitable for complex moulds While complex parts can be made using Compression moulding, depending on the material required and the design of the product, it is generally better suited to the production of larger, simpler objects. This is because the limited flow of material within the cavity often makes the elimination of voids, air traps and knit lines difficult when trying to produce more intricate parts. Contamination It is much easier to produce clean, consistently coloured rubber parts by Injection or transfer moulding. However, the uncured blank of compound used in Compression moulding can pick up specks of dirt which then simply get pressed and cured into the surface of the part, which the results in poor cosmetic appearance. Despite the part being dimensionally and physically acceptable, this often leads to an increase in reject rates and waste. Difficult to control flash Flash is a necessary by-product of Compression moulding due to the need to expel air during the moulding process by overfilling the mould cavity. This flash can also vary in thickness depending on the exact fill of each particular shot, leading to issues with variable dimensions of the part over across the split line. The flash has to be mechanically cut off and, again, is a thermoset material that cannot be recycled easily. The resulting split line witness mark is often more evident than on an Injection moulded part. This may create an aesthetic problem forthe customer. Generally, Compression moulded parts require more labour effort to trim and finish them, which can also increase the cost. Moulds can be damaged The repetitive nature of this process means that the moulds themselves can become victims of general wear and tear due to manually loaded blanks of material. Quite often, the mould is made to be run loose and is not bolted into a press. This can lead to deterioration of trim grooves and fine details, or in extreme cases, impact damage on mould faces caused by poor handling. Overall, the process of compression moulding is ideal when used appropriately and can help to keep overall project costs to a minimum, although individual part costs can be higher when compared to other techniques. It is critical to consider all the required aspects of a product, its performance and its life cycle when designing the most appropriate production solution, as each process technique has a different combination of costs, benefits and drawbacks. The proper solution may not require an expensive Injection mould tool and thus even if the part cost is higher, overall, Compression moulded solutions remain as relevant as ever.

pcb manufacturers: advantages and disadvantages of using a local cm - vse

Have you ever dove into something for which you were completely unprepared and immediately regretted it? I can tell you about one such instance. I and two others had been invited on a river rafting trip by a co-worker, who claimed to be an expert river guide. We soon discovered, however, that this nature adventure had more in store for us than we were ready for when we briefly lost control of our raft. Thankfully, we quickly returned to safety, but for a moment, I thought we might end up on the rocky bottom of the river bed.

Relying on an unknown contract manufacturer on the other side of the planet to build your new PCBAs is another type of risky, high-stakes adventure for which your company is likely unprepared. When it comes to maintaining maximum control over production, quality, and cost with a timely rollout, a local CM is a much better choice. This is especially true when youre innovating in Silicon Valley and need a reliable CM to manage your NPI runs. Heres a closer look at the potential PCB manufacturer advantages and disadvantages that come with partnering with a local CM.

On my rafting trip, I had unconsciously transferred feelings of trust and safety to someone whose skills on a river were unknown to me, and the results were disastrous. Likewise, it is short-sighted to commence production with any CM without having obtained unbiased information about the CMs integrity and performance record. You do not want to discover too late that your proprietary design has been stolen, or that your product reflects your CMs lack of quality processes.

This research is easily accomplished within the PCB manufacturing community in Silicon Valley, but its much more difficult to do when a CM is overseas. In these instances, you often must rely on the information provided by the CM, along with the limited historical and financial documentation available in the public domain.

Theres something invaluable about having the time and proximity to discuss your production needs in person. Its a significant benefit anytime youre deciding to work with a CM, but especially so when youre introducing a new product.

When overseas production stops due to design obstacles, or when the PCBAs fail electrical tests, a speedy response is needed from you. However, due to geographical distance, a prompt resolution is blocked. Instead, your engineers must rush to board flights, while your managers attempt to troubleshoot long-distance via conference calls and email, sometimes requiring the services of language interpreters. One day is lost due to time zones, and a second day is lost obtaining overseas management approval on the design and process changes.

By the time your company delivers updated schematics to the factory, how much production time has been lost? How much stress have your employees experienced? How much overtime has been used to respond to an overseas situation that could have been addressed in one day with a local CM?

New product launches are beset with complexity by the sheer number of phases involved. Design engineering, component engineering, compliance, sourcing, manufacturing and testing, quality control teams, and suppliers must all be closely coordinated. The ability to synchronize production faster and easier is one of the biggest advantages of choosing to partner with a local CM.

Of course, when faced with the decision of choosing a CM, it is important to have as much data in front of you as possible. Just as I now have a very solid list of pros and cons should I ever consider river rafting again, working through a robust list of advantages and disadvantages can aid in the decision-making process when choosing a CM. Consider the following points:

Careful examination of the pros and cons listed above is an excellent strategy to weigh the advantages and disadvantages of working with a local contract manufacturer. Sure, lower labor costs overseas are enticing, but that only becomes worth it once youre doing larger production runs using a vetted process. For your NPIs and low-volume runs especially, the optimum manufacturing scenario means having real-time oversight of PCB production, quality, and costs. Aligning with a reputable manufacturing partner, such as VSE, who has industry experience and engineering expertise will ensure a smooth product rollout.

french press vs keurig: which one is better? the coffee wave

The Best Answer:The French Press and the Keurig have their pros and cons. its really a matter of preference which one you like better. The French Press is more traditional, while the Keurig is a newer invention that lets you make coffee very easy. They both have their own advantages and disadvantages, but at the end of the day its totally up to your personal taste preference.

The French Press and the Keurig have their pros and cons. its really a matter of preference which one you like better. The French Press is more traditional, while the Keurig is a newer invention that lets you make coffee very easy. They both have their own advantages and disadvantages, but at the end of the day its totally up to your personal taste preference.

The French Press and the Keurig are both coffee makers but they are very different in some ways. If you brew the same amount of coffee using each coffee maker you will notice that the French Press makes more concentrated coffee than the Keurig.

The French Press uses the grounds in a way that extracts the most flavor and strength from your coffee beans without overstepping their brewing time limit. Because of that, it is a great remedy for many people who are looking for an intense raw caffeine punch with their morning beverage.

On the other hand, the Keurig is easier and faster than the French Press. The Keurig is very simple to use and uses electricity for its power source. With the Keurig you get a cup of fresh brewed coffee within seconds without having to leave the comfort of your home. Also, the Keurig has a lot more variety in terms of flavors and brands youcan use.

In this article, we will summarize the differences between these two coffee makers. We will talk about the many advantages and disadvantages of each one. By the end of this article you should have a clear picture of which coffee maker is a better fit for you.

The Keurig is an coffee machine that can make a cup of coffee extremely fast. It has been designed to work with instant and pre-ground coffee. It filters the water, brews the coffee grounds, and then uses hot water for extraction.

There is an easy way to do this that involves pressing down on one of the three buttons on the top while you add water, then turning it back up when done filling up with water which should be about half way or a little less than halfway full depending on how much water you want.

The Keurig Machine has some major advantages. The one that stands out the most is how fast it produces a cup of coffee. It only takes 1 minute and all you have to do is push a button. It also comes with an option for cold coffee, which is great for people who drink their coffee cold in the summertime.

It has some disadvantages as well though. One of its main drawbacks would be that you must stick with brands from Keurigs store because they use a particular type of filter mechanism (which they sell).

The French Press coffee maker is a traditional and simple way to brew coffee. It consists of a carafe with a plunger that pushes down the grounds, so it is completely immersed in hot water. The filters at the bottom of plunger will extract all of the coarse grounds and sediment from your coffee grinds, but still leave behind plenty of flavor.

French Press coffee uses strong coffee. Therefore, you need to make sure that you allow the hot water to cool. Too much heat causes the taste to change because of the chemical reaction between your coffee and the hot water. The ideal time is two minutes, but longer is acceptable (around 4).

The French Press requires no electricity so you can have a cup of fresh brewed coffee almost anywhere for any time. For some people the biggest con would be that they have to be sure when the coffee is ready because it isnt automatic as the Keurig.
