What are the common hardware shrapnel?
The production of metal shrapnel is a special process of cold stamping materials (metal or nonmetal) into parts (or semi-finished products) through stamping dies. Stamping is a kind of pressure processing method at room temperature, which uses the die installed on the press to exert pressure on the material to make it separate or deform plastically, so as to obtain the required parts. There are many kinds of metal shrapnel, which are widely used in machines and instruments, and there are many shapes, such as spiral, vortex and plate metal shrapnel. The development of metal shrapnel has a long history. Since ancient times, all kinds of metal shrapnel have been filled with precision mechanical instruments. Generally made of metal spring steel, it is used to control various movements of machine parts, such as reducing impact and vibration, storing energy, measuring force, etc.
