We are glad to share with you about the results of our work, company news, and give you timely developments and personnel appointment and removal conditions.
  • 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 comparable to some metal materials, and the products it manufactures have the advantages of good rigidity, deformation resistance, and wide operating temperature range. At the same time, the size of SMC products is not easy to deform and has excellent heat resistance; it can maintain its performance well in cold and hot environments, and is suitable for outdoor anti-ultraviolet and waterproof functions.


  • 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 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.


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


  • 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
