The contact shrapnel belongs to the category of hardware shrapnel and electronic hardware materials. It is an important part of various electronic products (mobile phones, connectors, car batteries). It is made of metal materials. When the contact shrapnel installed on the conductive film is pressed, the center point of the shrapnel contacts the PCB board to form a loop, and the current passing through it has the characteristics of strong conductivity and good hand feeling.

Contact shrapnel production process: in cold stamping processing by stamping dies, a special process of processing metal materials into parts. Stamping is at room temperature, using a mold installed on a press to apply pressure to the material to cause separation or plastic deformation , So as to obtain a stamping processing method for the required hardware.

As an important hardware component in the electronic system, contact shrapnel has a large amount of use, and there are many types. The production of metal shrapnel is original hand-made, and it is gradually moving towards mechanical automation. At the same time, the process performance of metal shrapnel is also on the rise. .
