The rapid development of the current automobile industry, motorcycle industry and machine tool industry has provided the driving force for the development of the traditional technology of cold forging. For example, the total national output of motorcycles in China in 1999 was 11.26 million. According to preliminary estimates in 2000, the total demand for automobiles in China will reach 3.3 million by 2005, including 1.3 to 1.4 million cars. The demand for forgings in the automotive industry is above 500,000 to 600,000 tons. Although the cold forging technology started in China is not too late, the development speed is far from the developed countries. So far, the weight of cold forgings on cars produced in China is less than 20kg, which is equivalent to half of developed countries. The potential is great. Strengthening the development and application of cold forging technology is an urgent task for China.
