In order to improve the performance of injection molds, many manufacturers will process their injection molds appropriately. Injection mold processing refers to the processing of molding and blank making tools, as well as shear molds and die-cutting molds. However, in many cases, the completion of mold processing will also reflect processing defects, leading to a decrease in mold performance. How can we build mold processing defects? The following measures can be taken to address mold processing defects. 1. Reasonable selection and dressing of grinding wheels The use of white corundum grinding wheel is better, as its performance is hard and brittle, and it is easy to generate new cutting edges, so the cutting force is small and the grinding heat is small. Use medium grain size in terms of grain size, and use medium soft and soft grinding wheels with coarse grain size and low hardness in terms of grinding wheel hardness. Good self excitation can reduce cutting heat.
