In order to easily demold the product, ensure product accuracy, strength and ease of mold processing, the selection of parting surfaces should consider the following principles

The machining accuracy of the new mold mainly has three aspects: dimensional tolerance, geometric tolerance and surface roughness. The processing accuracy requirements we usually put forward for mold manufacturers are mainly dimensional tolerances and surface roughness. Dimensional tolerances are ro......

The temperature of the mold directly affects the molding quality and production efficiency of the product, so a heating system needs to be added to the mold to meet the ideal temperature requirement.

In order to improve the wear resistance and corrosion resistance of the mold surface, it is often subjected to appropriate surface treatment.

The cutting edge of the mold is the part where the upper and lower molds bite each other, and generally requires flame quenching. During the SMC molding process, the product edges are sandwiched between the cut edges.

The main raw materials of SMC are composed of GF (special yarn), UP (unsaturated resin), low shrinkage additives, MD (filler) and various additives. SMC has the advantages of superior corrosion resistance, soft quality, easy engineering design, flexibility, etc. Its mechanical properties are compar......
