The material used in the biodegradable plastic ball is PLA, which can be decomposed by bacteria in the soil or in a humid environment and will not pollute the environment, but the manufacturing method of the biodegradable plastic ball is completely different from that of the POM plastic ball. The sh... read more
The manufacturing of POM plastic ball mold must calculate the shrinkage rate of POM material, but POM plastic ball mold is different from other POM products. POM plastic ball is a solid sphere. The larger the size, the shrinking rate will be doubled, so POM plastic The manufacturing of the ball mold... read more
The density of solid plastic balls cannot be exactly the same due to material reasons and differences in injection molding processing technology. For customers who are not demanding, such differences will not have much impact, but some demanding customers , The density of the plastic solid balls mus... read more
PVC plastic ball is manufactured by injection molding process, but because PVC material is corrosive, PVC plastic ball mold material should be made of corrosion-resistant mold steel. Generally, the commonly used mold steel is made of S136, which has high hardness. The advantages of corrosion resist... read more
