Longevity of hardware shrapnel

The hardware shrapnel is classified into the hardware stamping parts and electronic hardware materials category. It is made of stainless steel or manganese material after heat treatment. It is an important part of the switch. With the help of the conductivity of the metal shrapnel, it plays an excellent role as a switch between the operator and the product. At the same time, using the stable resilience of the guozi (automatically return to position after pressing), and the long life span, provide the operator with excellent tactile response.　　The production of metal shrapnel is an exceptional skill in processing materials (metal or non-metal) into parts (or semi-finished products) through cold stamping processing by stamping dies. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the data at room temperature to cause separation or plastic deformation, and then obtain the required parts.
