Mold processing refers to the processing of forming and blanking tools, in addition to shearing dies and die-cutting dies. Under normal circumstances, the mold consists of two parts, an upper mold and a lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the mold will be obtained or the corresponding waste will be removed. Parts as small as electronic connectors and as large as automotive dashboards can be molded. Progressive die refers to a set of molds that can automatically move the processed workpiece from one station to another, and get the molded part at the last station. Mold processing technology includes: cutting die, blanking die, compound die, extrusion die, four slide rail die, progressive die, stamping die, die cutting die, etc.
