Technological process of precision hardware processing

For the process flow of precision hardware processing, first of all, the metal strip is uncoiled, cut, blanking, blanking (skip if there is no shape material), drawing, pressing and bending. Although there are so many steps, this is only the first step of the stamping process.
The second step (appearing in the subsequent stamping process) includes stamping, forming, turning, turning, stamping, cutting, cutting, stamping, missing, necking, expansion, semi stamping (sometimes seen in knockout holes, punching bosses, non precision stamping), packaging, internal and external edge repair and calibration. This is usually the medium-term process of stamping.
The finishing work is the post-processing of precision hardware processing. The main finishing work of stamping parts includes electroplating, blackening, shot blasting, polishing, spraying and some heat treatment, etc.
The main characteristics of precision hardware processing technology are: high productivity, low mold cost, no need for sheet metal cutting, high production efficiency compared with other metal processing methods, stable quality compared with ordinary cutting methods, low material consumption and tool consumption, and 35% of the cost of progressive die can be saved. In this way, both productivity and safety can be achieved.
