What are the requirements for materials in general Plastic injection design

 

1. Easy to process Plastic injection design mold parts are mostly made of metal materials, and some structural shapes are still very complex. In order to shorten the production cycle and improve efficiency, the mold materials are required to be easy to process into the shape and accuracy required by the drawings.

2. Plastic injection design, good wear resistance. The gloss and accuracy of the surface of the plastic part are directly related to the wear resistance of the mold cavity surface, especially when glass fiber, inorganic fillers and certain pigments are added to some plastics. They and the plastic melt flow at high speed in the runner and mold cavity, and they have great friction on the surface of the cavity. If the material is not wear-resistant, it will wear out quickly, which will damage the quality of the plastic part.

 

3. High corrosion resistance. Many resins and additives have a corrosive effect on the surface of the cavity. This corrosion causes the metal on the surface of the cavity to corrode and peel off, the surface condition becomes worse, and the quality of the plastic parts deteriorates. Therefore, it is best to use corrosion-resistant steel for Plastic injection design, or chromium plating or cymbal nickel treatment on the cavity surface.

 

4. Good dimensional stability. During injection molding, the temperature of the injection mold cavity must reach above 300°C. For this reason, it is best to select tool steel (heat-treated steel) that has been properly tempered. Otherwise it will cause changes in the microstructure of the material, resulting in changes in the size of the mold.

 

5. Plastic injection design is less affected by heat treatment. In order to improve the hardness and wear resistance, the mold is generally heat treated, but this treatment should make the size change small. Therefore, it is best to use pre-hardened steel that can be machined.

 

6. Plastic injection design with good polishing performance. Plastic parts usually require good gloss and surface condition. Therefore, the roughness of the cavity surface is required to be very small. In this way, the surface of the cavity must be surface processed, such as polishing, grinding, etc. Therefore, the selected steel should not contain rough impurities and pores.
