Stamping dies are cold pressing process, material (ferrous or non-ferrous), machined parts (or semi-finished products) in a special technical equipment, called the cold stamping die (commonly known as die). RAM was installed on a press mold at room temperature on the material pressure to produce separate or plastic deformation, thus achieving the required parts of a pressure process method. Manufacturing stamping die materials are steel, carbide, steel-bonded hard alloy, zinc alloy, low melting point alloys, aluminum bronze, polymer materials, and so on.
