If the mould of PVC plastic pepper ball is not well made, it will have a great impact on the quality of PVC plastic pepper ball. The appearance of PVC plastic pepper ball requires bright and beautiful, and the closing line must be small. To achieve these quality requirements, the mould of PVC plastic pepper ball must be well made, otherwise it will be difficult to ensure the quality of PVC plastic pepper ball.

PVC plastic pepper ball mold must be made into mirror effect to make high-gloss plastic pepper ball products, and high-gloss mold manufacturing must use quenched mold steel to polish into mirror effect. Another factor is that PVC plastic is corrosive, and ordinary mold steel will be corroded by acid gas generated by PVC melting, so the mold steel used in PVC plastic pepper ball mold must be corrosion-resistant materials. For example, the die steel like S136 is the ideal die steel for manufacturing PVC plastic products. The PVC plastic pepper ball die must be well designed for exhaust. If the exhaust is not well designed, it is easy to produce irregular bubbles inside the plastic pepper ball when manufacturing the plastic pepper ball.
