PP plastic ball is light in weight and environmentally friendly and safe. It is the only plastic ball that has passed the US FDA quality standards in the food and pharmaceutical fields. There are several methods for manufacturing PP plastic balls:
1. Large-size plastic PP balls, PP plastic balls with a diameter greater than 40mm are generally manufactured by using plastic rough ball machine tools, and then processed by the plastic ball milling machine finishing process, because large-size plastic The ball is produced by injection molding process. The product has severe shrinkage and low yield, so it can only be manufactured by machine tool processing.
2.Small size plastic PP balls, PP balls with a diameter of less than 30mm are manufactured by injection molding process. PP plastic has good fluidity and is processed by injection molding machine. A set of molds can be processed by injection for dozens to hundreds Quantity, high efficiency, and good accuracy. After the plastic ball milling machine is finished in the later stage, the cost advantage of PP balls can be well reflected.
3. Blow molding manufacturing process of plastic PP hollow spheres: Plastic PP hollow spheres are also widely used. Plastic PP hollow spheres are manufactured by the blow molding process. The hollow sphere mold for blow molding is simple and the cost is low. The application is basically limited to use as a liquid surface covering ball in the electroplating industry, and the accuracy is not high. The PP hollow ball manufactured by the blow molding process can completely meet the requirements.
