What is Cold Stamping and Mold Making?

Cold stamping is the application of pressure to a material by means of a die mounted on a press to cause separation or plastic deformation. Thereby obtaining a pressure method of the required parts (commonly known as stamping parts or punching). Because it is usually processed at room temperature of the press, it is called cold stamping.Get more news about Micro Precision Cold Extrusion Part Exporter,you can vist our website!
The main feature of the cold stamping production process is that it is processed by die and stamping equipment, which is easy to automate, high in productivity and easy to operate. For ordinary presses, each piece can produce several to dozens of stampings per minute, while high-speed punches can produce hundreds or even thousands of stampings per minute. The parts obtained by cold stamping generally do not need to be machined, so it is a method of saving energy and saving raw materials. Since the raw materials used for cold stamping are mostly sheets or strips with good surface quality, the dimensional tolerances of the stampings are guaranteed by the die, so the dimensions are stable and the interchangeability is good. The cold stamping product has a thin wall, light weight and good rigidity, and can be processed into parts with complicated shapes, from the second hand of the clock to the longitudinal beam of the car and the cover.
However, since the die manufacturing is generally a single-piece small-volume production with high precision and high technical requirements, it is a technology-intensive product with high manufacturing cost. Therefore, cold stamping production can only achieve higher economic effects in the case of large quantities.
In summary, cold stamping has unique characteristics compared with other processing methods, so it is widely used in industrial production, especially in mass production. A considerable number of industrial sectors are increasingly using cold stamping products, such as machinery manufacturing, vehicle production, aerospace, electronics, electrical appliances, light industry, instrumentation and daily necessities. In these industrial sectors, the proportion of stamping parts is quite large. Many parts that have been manufactured by casting, forging and cutting methods have been replaced by stamping parts with light weight and good rigidity. Through stamping processing, productivity is greatly improved and costs are reduced. It can be said that if the stamping process is not widely used in production, it is difficult to upgrade the product in many industrial sectors to improve productivity, improve quality, and reduce costs.

1. Cold stamping process aspect
Research and application of important trends in the development of various stamping technologies aimed at increasing productivity and product quality, reducing costs and expanding the range of stamping process applications. At present, domestic and rapid emergence of advanced technology for the production has a precision stamping press, a flexible membrane forming, superplastic forming, multi-point forming, explosion and other high-energy electromagnetic forming, high precision stamping and cold extrusion technology, etc. . These stamping advanced technologies have achieved good technical and economic effects in actual production.
Precision stamping is an effective method to improve the accuracy of stamping parts, and an important way to expand the range of stamping processing. At present, precision precision can reach IT6~IT7, and the thickness of sheet can reach 25mm. The fine punching method can not only be punched, but also can be formed (precision bending, deep drawing, flanging, cold extrusion, embossing and countersinking, etc.).

2. Die design and manufacturing aspects
Stamping is the basic condition for the production of die. At present, there are two trends in die design and manufacturing that should be given enough attention.
(1) mold structure and precision are developing in two aspects
On the one hand, in order to meet the needs of high-volume, automatic, precision, safety and other large-scale automated production. The die is developing in the direction of high efficiency, precision, long life, multi-station and multi-function; On the other hand, in order to adapt to the rapid requirements of product upgrading in the market, the design and manufacturing of various rapid prototyping methods and simple economical dies have been rapidly developed.
