The development of science has a great influence on cold extrusion technology.

At present, China has been able to lead, tin, aluminum, copper, zinc and its alloy, low carbon steel, medium carbon steel, tool steel, low alloy steel and stainless steel and other metal for cold extrusion, and even for bearing steel, high carbon steel, high speed steel, etc. can also be a certain amount of deformation of cold extrusion. Cold extrusion parts are all kinds, the most weight of up to 30 kg, the lightest only 1 grams. In the use of mold material, in addition to the use of high speed steel, bearing steel, Gao Tangao chromium alloy tool steel, but also the use of a number of new die steel CG2, LD, 65Nb, etc.. In extrusion process parameters selection and die structure design, the initial use of the optimization design and computer aided design and manufacturing (ie, CAD/CAM), so that the mold structure is more reasonable, extrusion process parameters more close to the actual. In the extrusion equipment, China has the ability to design and manufacture all levels of tonnage extrusion press. In addition to the use of universal mechanical pressure machine, hydraulic machine, cold extrusion press, but also successfully used friction press and high-speed high-energy equipment for cold extrusion production.

The development of science has a great impact on the cold extrusion technology, specifically, the impact of the computer in the process analysis, mold design, manufacturing and process control in the application of cold extrusion technology. China will further develop this new technology. Development of cold extrusion technology is mainly from the following aspects:

1 expanding the application range of cold extrusion technology in a certain range, and gradually replaced by casting, forging, deep drawing and cutting;

2 to improve the accuracy and surface quality of cold extrusion parts, and to produce more complex products;

3 kinds of raw materials used for cold extrusion, the more ideal surface treatment and lubrication method;

4 further use of CAD/CAM and optimize the design, improve and speed up the mold design and manufacturing, the development of a more reasonable mold structure;

5 to find more suitable for cold extrusion die material and heat treatment method, in order to extend the service life of the mold;

6 further development of new technology, such as warm extrusion, isothermal extrusion, hydrostatic extrusion and high speed extrusion, is studied and applied;

7 to develop a cold extrusion machine for cold extrusion, so that the blank and the workpiece can be safely and automatically feed and out parts, in order to further improve the productivity.
