The manufacturing process of solid plastic balls is mainly divided into injection molding process and machining process. The manufacturing process of plastic shell pepper balls is mainly based on blow molding process and welding process. Because the manufacturing process of solid plastic balls is relatively simple, the price of solid plastic balls is lower than that of plastic shell pepper balls

The post-processing technology of solid plastic ball and plastic shell pepper ball is basically the same, and both need to be processed with a ball grinder, but the processing efficiency of solid plastic ball with a ball grinder will be higher, because the solid plastic ball can be grinded with a certain pressure during the grinding process, and the processing of plastic shell pepper ball needs to be grinded slowly to have a certain accuracy. The above is the difference between the manufacturing process of plastic hollow ball and plastic shell pepper ball.
