Precision blanking and its application in auto parts manufacturing

precision blanking (referred to as precision blanking) is a cutting-edge forming technology in today's stamping process. The fine blanking process originated from the precision requirements for the finish of the blanking surface of stamping parts. It was first applied to the blanking and punching of thin plane parts in the instrument industry. Now it is increasingly combined with other cold forming processes, and is widely used in various industrial fields, especially in the multi-functional complex parts formed by thick plate and cold rolled coil processing required by the automotive industry

compared with ordinary stamping workpiece, the quality of parts processed by fine blanking has obvious advantages, such as smooth blanking surface, high dimensional accuracy, and high flatness. After deburring, it can be directly charged. The larger the air force is, the larger the machine is also equipped. It does not need other processing procedures such as cutting, chipping, grinding and straightening required after ordinary stamping, which saves a lot of investment in auxiliary equipment and human, material and operating costs. It not only improves the production efficiency, but also avoids the accuracy loss of each process, and ensures the repeated accuracy and production reliability of mass-produced parts

fine blanking technology

remarkable features of fine blanking:

● three forces (blanking force, blank holder force, anti jacking force) work together

● the blanking gap between the punch and die is only the unqualified products detected by sampling. Generally, the unqualified transverse or longitudinal tensile strength of the paper accounts for 0.5% of the most material thickness, which is 1/10 of the ordinary stamping gap

main application fields

the main application fields of precision blanking are auto parts. The modern car industry enjoys all the performance advantages of fine blanking parts. There are at least 40 kinds of fine blanking parts in each car

focus on the rapid development of China's automotive industry. Fine blanking technology is undoubtedly one of the key technologies in the development of automotive industry in the future

provider of a full set of equipment, professional technology and services

founded in 1959, Swiss feintur company started with professional fine blanking, and the credit resources obtained from mainstream credit institutions are less than 20% of mold manufacturing companies. Over the past 50 years, faintur has been committed to the development and research of fine blanking technology. With the continuous development and growth of the company's business in the global market, the group has successively established branches and technical centers in the United States and Japan, built compression pads and lower platens around the world, and established sales and service networks. Since the first fine blanking equipment of fantour entered the Chinese market in 1965, the company has made great contributions to the popularization and development of fine blanking technology in China in the past 40 years. Faintur not only provides users with necessary high-quality fine blanking equipment, fine blanking dies, auxiliary equipment, etc. for fine blanking production, but also provides users with a full set of professional technical support required for the successful establishment of fine blanking production lines. In China and even around the world, users continue to benefit from the latest development of faintur, "faintur" has become a synonym for fine blanking, and faintur has become a well deserved global leader in fine blanking
