  • 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.

  • 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 roughly divided into: outline size and cavity size.

  • 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.

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

  • The smc mold needs to be heated, not cooled. The temperature of the mold is usually between 140 and 160. In mold design, maintaining mold temperature is very important. The mold is easier to fill, the product is not easily deformed, and the surface is better. Commonly used heating systems are steam, oil, high-pressure water or electricity. When the temperature of the mold design system pays special attention to make the temperature of the mold on the entire surface consistent, a uniform temperature can reduce deformation, improve the size of stability, and the uniformity of the product surface.
