The production and processing of PA plastic pepper ball consists of injection molding blank ball, grinding ball machining, polishing and other processes. In the grinding process, PA plastic pepper ball has always been operated with water, while PA plastic pepper ball has a high water absorption rate, so the allowance for increasing the water absorption size of PA plastic pepper ball should be reserved during the processing.

When the PA plastic pepper ball is ground by a plastic pepper ball mill, the processing time is generally more than 20 hours. After long-term water absorption, the size of the PA plastic pepper ball will become larger. After grinding, the size will be larger than the actual size. When the plastic pepper ball is processed and dried, the size of the PA plastic pepper ball will become smaller. Only in this way can the size of the processed plastic pepper ball meet our processing accuracy requirements.
