There are some differences between the materials used in the mold of the elastic plastic pepper ball and the mold of the engineering plastic pepper ball. Because the materials used in the elastic plastic pepper ball are very fluid, it is easy to produce criticism and shrinkage, so the quality of the mold materials will also affect the quality of the elastic plastic pepper ball products.

Generally, the material used for the elastic plastic pepper ball mold is S136 stainless steel. The advantage of S136 is that it is corrosion-resistant and can be quenched and hardened. Because some elastic plastic raw materials are acidic and can be corroded by ordinary mold steel, it is necessary to use corrosion-resistant mold steel to manufacture the elastic plastic pepper ball mold. After heat treatment, the hardness of the mold steel is above 53 degrees, which can well reduce the batch of plastic blank balls and provide convenience for the subsequent grinding and polishing of plastic pepper balls.
