PVC plastic pepper balls are manufactured by injection molding technology. However, due to the corrosiveness of PVC materials, the mold materials of PVC plastic pepper balls should be made of corrosion-resistant mold steel. The commonly used mold steel is S136, which has the advantages of high hardness and corrosion resistance.

How to make the PVC plastic pepper ball mold with ordinary mold steel? PVC will corrode the mold during injection molding, and the mold surface will be corroded into a frosted surface, which has a great influence on the surface appearance of the plastic pepper ball. Moreover, due to the corrosion of the mold surface, the plastic pepper ball will easily stick to the mold, which makes it difficult to hold the mold. In addition, the PVC plastic pepper ball mold should be made of heat-treated S136 material, so that the plastic pepper ball blank ball manufactured in this way will not be criticized, and the precision of the plastic ball is high, which will be used for subsequent processing.
