Processing means: cold / hot stamping, extrusion, rolling, welding, cutting, etc. also include other processes, and the definition is relatively broad; Stamping parts: the most used in hardware processing, referring to the forming of specified shapes from steel / non-ferrous metal sheets and other sheets by a mold under room temperature conditions with the pressure provided by a press. It includes some electronic devices, auto parts, decorative materials, etc. The stamping parts we usually refer to generally mean cold stamping parts. For example, if you want to turn an iron plate into a fast food tray, you have to design a set of molds first. The working surface of the mold is the shape of the tray. Press the iron plate with the mold, and it will become the tray you want. This is cold stamping, which is directly stamping the hardware material with the mold.

[0003] However, when the existing stamping device produces hardware stamping parts, some iron filings will fall off the outside of the material during stamping.
