15-year precision mould making

   Along with the extensive application of plastic mold parts, plastic mold parts are processed into molding of various kinds, such as injection molding, compression molding, extrusion molding, blow molding, vacuum molding etc.. Because China mould parts industry grows, continuous improvement and development of domestic and international market, and the customer's understanding of the changing, more and more mature, the purchaser will also go into professional field. Today, Yi Ze mold teach you how to choose the quality of plastic mold parts.The next,we will know the advantages of plastic mold parts.
   The main advantages of plastic mold parts are six: wear resistance, strong toughness, fatigue fracture properties, high temperature performance, thermal fatigue resistance and corrosion resistance.
   The advantage of plastic mold parts is specific, the wear resistance of plastic mold parts and mold material of carbide type, quantity, shape, size, distribution of contact. In addition the hardness is the main factor affecting the wear resistance. Under normal circumstances, the higher the hardness of the mold parts, the smaller the wear. The toughness of plastic mold parts is mainly and the carbon content, grain size and microstructure of die and mold parts. The fatigue fracture behavior of plastic parts is mainly determined by the strength, toughness, hardness, and the content of the inclusions in the material. The plastic mold material should have high resistance to tempering stability, in order to ensure that the mold at the working temperature, with high hardness and strength. Cold and hot fatigue is one of the main forms of failure of hot die, which should have high resistance to cold and hot fatigue. Plastic mold at work, due to the presence of chlorine, fluorine plastic, after heat decomposition precipitation of HCI and HF strong corrosive gases, erosion of the mold cavity surface, increase the surface roughness, increased wear failure, therefore, it is important to plastic mold components corrosion resistance.
