Title: cold forging technology

Description: Modern cold forging and stamping are closely linked, after nearly zoo years of development, also formed an applied technology science and manufacturing technology. A brief history of its development can be illustrated by the following important examples.

Tracing to a little earlier, modern cold forging technology began in the late eighteenth Century. Since the French Revolution, the French extruded lead from the small hole into bullets, extrusion has become a new term, a new process. In 1830, a French mechanical press was used to squeeze out the lead and tin pipes in France.

In 1886, a hollow bullet shell was formed on the French market. The above examples belong to the hot forming process of hot pot, but they are the basis of cold forging.In 1900, the L. E. Hooker of the United States obtained the positive extrusion of the hollow parts of the nonferrous metal gills, such as lead, zinc, aluminum and brass; the patent of the law and the manufacture of the brass buckle. During the first World War, the United States manufactured brass cartridges by positive extrusion, and Germany developed steel cartridges. In 1935, the Germans adopted the phosphating treatment and new lubricants invented in the previous year, and made t steel bullet shells by extrusion, and became military secrets of World War II. In 1940, the cold extrusion (Newmayer method) of steel shell and cylinder parts appeared.

After 1945, not only the cold extrusion of steel has reached practical conditions, but also the production order of cold forging, such as pier forging, extrusion, thinning drawing, die forging, etc., is formed, such as compound extrusion, some new cold forging technology and equipment. The hydrostatic extrusion process was started in 1893 by J. Robe in 1934 and Bridgman in Harvard University, until the year of 1958~1962.The problem. O. 3.3 modern cold forging In recent decades, cold forging technology has developed more rapidly. National Cold Forging Group). At present, many countries In 1963, the international Cold Forging Association (ICFG) (Inter- This has established corresponding associations and associations for academic exchanges and academic and (including China).The development of cold forging technology in Japan is 2  industrial linkages have played an important role. It started. First, the cold forging of a thousand bicycle parts is applied. Imported from abroad in early 50s zeroth Century Related papers and patents and introduced to Japan Textile machinery and some tools production industry.For example, the shaft of a bicycle. Then cold forged into the motorcycle, Cold forging technology in Japan in 70s By 60s, entering the auto industry In considering the theoretical depth, we also enter And other departments, such as photographic equipment and electrical industry. Die strength analysis and die design are developing to a wide extent. In advance The life of the mould is improved. At the same time, the study of system theory, And make the computer technology through the research and surface treatment of mold materials. Since then, Japan has devoted itself to the high precision of cold forging technology. Operation and laser technology are also used in cold forging Achievements. Machining of complex shape parts The field of work is great. 80 years The application and research of this area has been important for nearly half a century. The cold forging technology of the United States in the fastener industry has been continuously developed. The application is more significant. For example, the United States, 1965 cold forging in the automotive industry, standard France also accounts for 1oy O~80%. For example, before 1980, Total output of annual cold forgings 100 thousand tons, 400 thousand tons in Japan. For example, the steel used for cold forging in the late twentieth Century is 115. Car parts account for 80%, former West Germany and The United States, Germany and other countries are also close to the use of 40kg/ 4 "cold forging". Ten thousand tons, former West Germany At present, the shape of cold forgings, and China's 4~5kg/ station, the average Japanese 42kg/ Taiwan. Four There are more than 1000 types; a small number. In the late 1980s,Foreign cold forging parts

Q:.Do you have your own engineering team?

A:We have structural engineering design team and mold manufacturing team. 

Q: can we visit your company?

A: Yes, but you need to notify us ahead of time before you come. 

Q:Do you have engineering team?

A: We got structural engineering design , mold manufacturing team and we got 15 CNC so we can easier to make any sample to service customer. 

Q:ADC12 be welded with aluminum profiles? Is it strong enough to bear?

A:We have tried that ADC12 can be dumb argon welded with aluminum profiles, but there will be pores at the weld, because of the density of the reason, bearing a large force will also fracture. So you need to do your tension test.

Q: can the goods be returned after shipment?

A: Yes, the defective products can be sent to me. After we receive the defective products, the quality department will check the reasons. That's our reason. We will arrange for the refund.
