Stamping comes under one of the dispensation methods
The various methods present for metal processing are:
Squeeze is a method where a piece of metal is processed into a product. This is done by applying pressure on it. Pinch is a dispensation method where a section of it is taken from the plate which in turn becomes a different product pulled out from a metal plate. The next processing method is known as bend. As the name suggests it is a method where a metal is bent. It includes sharp bend and round bend. The next process is crush where when applied pressure the excess metal is pushed outside automatically. It is known as a forging process.
It is so obvious that when discussed about stamping it would cover the concept of dies. They are much worthy to be said as the 'life' of stamping. The accuracy of die plays a vital role in deciding to the quality of the end product. A die comprises of a number of parts which makes it an intricate component. Manufacturing a die requires a lot of technical skill. There a professionals to produce the die and the manufacturer will purchase die from these die manufacturers.
For instance, when a product is to be manufactured in a particular shape it needs a lot of concentration when preparing a die. If proper attention is not given when designing a die the required shape will not be the end product and it cannot be manufactured. If proper technical skills is not put forth during the making it might even ruin the product in the end. A cheaper die range from 20000 to 30000 yen. A normal die ranges from a few million to tens of millions of yen.
The utmost complexity in designing a die is that it has many subdivisions during manufacturing. It has to be done by a step by process until the desired shape is retrieved. Much number of steps will be required if it is a complicate design because different die will be pressed to produce a single product. This requires a rich knowledge and a strong technical skill.
Each item has its own advantage and its disadvantages. When all the process is running sequentially the operators should be careful and cautious that it should not be interrupted from anything as it creates a disaster in the quality of the product. It can also be affected by the temperature and the humidity. Thus this process is not by setting up or by pressing a button in a cnc machine but by fine tuning the product with high care and accuracy to obtain the great output.
