2019-12-29 1563

  Mold making refers to the processing of forming and blank making tools, in addition to shear mold and die-cutting mold. Generally, the mold has two parts: upper mold and lower mold. The steel plate is placed between the upper and lower dies to realize the material forming under the action of the press. When the press is opened, the workpiece determined by the die shape will be obtained or the corresponding waste materials will be removed. As small as electronic connector, as large as the automobile dashboard, the workpiece can be molded with mold. Progressive die refers to a set of die which can automatically move the workpiece from one station to another and get the forming parts at the last station. Die processing technology includes: cutting die, blanking die, compound die, extrusion die, four slide die, progressive die, stamping die, die cutting die, etc.
