A punch press is a stamping press. In national production, stamping technology has become increasingly widely used due to its advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be achieved by mechanical processing through various mold applications compared to traditional mechanical processing.

In the die-casting process of products in the casting industry, the occurrence of product defects such as shrinkage marks, sand holes, cracks, and bubbles is often caused by mold temperature control.

A combined plastic mold used for compression molding, extrusion molding, injection molding, blow molding, and low foaming molding, mainly comprising a concave mold with a variable cavity composed of a concave mold composite substrate,

In order to improve the performance of molds, many manufacturers will perform appropriate processing on their molds. Mold processing refers to the processing of forming and blank making tools, as well as shear molds and die-cutting molds.
