Chongqing steel stamping / Chongqing stainless steel stamping factory stamping 15025387227 [Goldsmith] Chongqing stamping products processing characteristics: As cold stamping has the advantage of the above-mentioned outstanding, so it has been widely used in mass production, it plays a very important in modern industrial production The position is the defense industry and civilian industrial production essential processing methods. Stamping process must have the appropriate mold, and the mold is a technology-intensive products, the manufacturing is a single piece and small batch production, with difficult processing, high precision, high technology, high production costs (about 10% of the product cost to 30 %) specialty. Therefore, only in the case of stamping parts production volume, advantages stamping process can be fully reflected, to obtain good value for money. Chongqing stamping products: stamping parts vary in shape, size and accuracy, the process used is also different. According to the deformation characteristics of the material can be cold stamping process is divided into two separate step and forming step. Separation process - refers to the blank under the red pressure, stress and deformation portion After reaching the ultimate strength σb, the blank broken to produce separation. There are cut separation step and punching and so on. Molding step - refers blank punch under pressure, stress and deformation portion reaches the yield limit σs, but did not reach ultimate strength σb, the blank is plastically deformed into a certain shape, size and precision parts processing step. Forming process is bending, deep drawing, flanging, spinning like. yyhkcn_cqjjmj_tml Phone: 023-88119759 400 Phone: 4000230034 Mobile: 15025387227 Contact: Mr. Sun Address: Jiulongpo District of Chongqing Hua Yan Xishan Village, a community stamping products / Chongqing stamping / Chongqing Mould http: //www.cqjjmj. com /
