Stamping is a processing method using cold stamping. This process uses equipment to cut, bend, or shape the material to the size and shape specified by the mold. Stamping can be roughly divided into multiple processing methods such as shearing, bending, forming, and drawing. Normally, stamping is the processing of cold metal plates, as opposed to forging, which is the forming of hot metal. The characteristics of general stamping products are high strength, structural integration, and stability. Technical application fields are various, such as heavy industry, mechanical and electrical industry related parts, auto parts and motorcycle parts, and other hardware parts.
