Stamping parts rely on press and die to impose external force on plate, strip, pipe and profile, so as to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece (stamping parts) forming processing method. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot and cold rolled steel plates and strips.
Stamping parts are the production technology of parts with a certain shape, size and performance by means of the power of conventional or special stamping equipment, so that the plate is directly subjected to the deformation force and deformation in the mold. Sheet material, die and equipment are the three elements of stamping processing. Stamping process is a cold deformation process of metal. Therefore, it is called cold stamping or sheet stamping, referred to as stamping. It is one of the main methods of metal plastic processing (or pressure processing), also belongs to the material forming engineering technology.
Die casting is a kind of pressure casting parts. It uses the pressure casting mechanical die casting machine equipped with casting mold to pour the heated liquid copper, zinc, aluminum or aluminum alloy into the feeding port of the die casting machine. Through the die casting machine, copper, zinc, aluminum or aluminum alloy parts with the shape and size limited by the mold are cast. Die casting parts in different places have different names, such as die casting parts, pressure casting, die casting, die casting aluminum, die casting zinc, die casting copper, copper die casting, zinc die casting, aluminum die casting aluminum die casting, aluminum alloy castings, aluminum alloy die casting parts, etc.
