There are several methods of stamping mold processing:
1, hand grinding polishing. This is a more traditional surface mold processing methods, mainly rely on the operator’s experience and technology to process, but manual polishing comparison time-consuming, inefficient, some more complex surfaces or stitch grinding polishing will be more difficult to deal with.
2, mechanical grinding processing. Commonly used grinding equipment has flat grinders, inner and outer round grinders, tool grinders and so on. In order to ensure accuracy, the general use of numerical control methods for mold processing. According to the different part shape to choose the appropriate type of grinder, plate type parts choose flat grinder, arc and swing surface parts using internal and external round grinder or tool grinder.
3, mechanical CNC milling machine. This stamping tensile mold processing method is not only fast processing efficiency, but also good processing quality, in addition to the inner sharp angle of the cavity and very narrow and deep cavity, other aspects can be competent. In foreign countries has become the mainstream process of stamping mold processing, China is also actively developing.
Stamped stretch mold processing can ensure the accuracy of each relevant parts in the mold, increase its ability to resist bending, anti-bias, to avoid uneven wear of the mold.
