Company technology research and development team has been committed to the hot and cold precision molding technology and composite extrusion process research, independent research and development, design, manufacturing of all kinds of complex shaped forgings has accumulated rich experience, has been developed mainly covering aviation manufacturing, high-speed rail transit, military machinery, engineering machinery, mining machinery, automotive, petroleum, chemical industry, electric power and other fields. It mainly focuses on the design and development of non-ferrous metals and complex special-shaped forgings in the background of automobile, high-speed rail and aircraft lightweight manufacturing.

At present, the cold extrusion of lead, tin, aluminum, copper, zinc and their alloys, low carbon steel, medium carbon steel, tool steel, low alloy steel and stainless steel and even bearing steel, high carbon and high aluminum alloy tool steel, high speed steel and other metals can be carried out. Cold extruded parts are manufactured in a variety of sizes, up to 30 kg and as light as 1 gram. In terms of the use of die materials, in addition to the use of high-speed steel, bearing steel, high carbon and high chromium alloy tool steel, many new die steels such as CG2, 65Nb, LD, etc. In extrusion process parameter selection and die structure design, optimization design and computer aided design and manufacturing (CAD/CAM) are preliminarily used to make the die structure more reasonable and extrusion process parameters more close to the reality. In extrusion equipment, our country has the ability to design and manufacture extrusion presses. In addition to general mechanical press, hydraulic press and cold extrusion press, friction press and high speed high energy equipment have been successfully used for cold extrusion production.

The development of science has a great impact on cold extrusion technology. Specifically, the application of computer in process analysis, mold design, manufacturing and process control has an impact on cold extrusion technology. The new technology will be further developed in our country. The development of cold extrusion technology should mainly start from the following aspects:

1. Expand the application range of cold extrusion technology, and gradually replace casting, forging, deep drawing and cutting within a certain range;

2. Improve the precision and surface quality of cold extrusion parts to produce more complex geometric shapes;

3. Expand the types of raw materials used in cold extrusion, and study more ideal surface treatment and lubrication methods;

4. Further use of CAD/CAM and optimization design, improve and speed up mold design and manufacturing, develop a more reasonable mold structure;

5. To find more suitable for cold extrusion mold materials and heat treatment methods, in order to extend the service life of the mold;

6. Further develop the research and application of new technologies such as warm extrusion, isothermal extrusion, hydrostatic extrusion and high speed extrusion;

7. Develop a multifunctional cold extrusion machine suitable for cold extrusion, so that the blank and parts can be safely and automatically fed and released, in order to further improve productivity.
