Precision metal stamping parts processing: with the characteristics of thinness, uniformity, lightness and strength. Stamping can produce stamping parts with ribs, ribs, undulations or flanging that are difficult to manufacture by other methods, so as to improve its rigidity. Due to the selection of fine molds, the precision of the workpiece can reach the level of 0.01mm, and the repeatability is high, and the standard is consistent, and it is possible to punch out holes, bosses, etc.

The stamping of fine metal stamping parts is mainly classified according to the process, which can be divided into two categories: separation process and forming process. The separation process can also be called punching, and its purpose is to separate the precision stamping parts from the sheet along a certain contour line, while ensuring the quality requirements of the separation section.

The stamping of fine metal stamping parts is an efficient production method. The multi-station progressive die can be used to complete multiple stamping processes on one press, and realize the fully automatic process from strip uncoiling, leveling, punching to forming and finishing. Production. High production efficiency, good working conditions, low production cost, generally can produce thousands of pieces per minute. The purpose of the forming process is to make the sheet plastically deform without breaking the billet to make a workpiece of the required shape and size.

In actual production, multiple processes are often combined and applied to one workpiece. Punching, bending, shearing, deep drawing, bulging, spinning, and straightening are several important stamping processes.
