The manufacturing method of plastic pepper balls is quite different from that of ordinary plastic balls. To manufacture plastic pepper balls, the plastic raw materials must be drawn into very fine filaments first, and then cut with a special cutting tool. After the plastic filaments are cut into filaments, the corresponding abrasive is added to grind them in the machine. This grinding process is complicated and requires special grinding equipment, because water cannot be added to cool them during the grinding process. Only the circulating cooling water built in the machine can be used to cool the machine, so the process is difficult. At present, there are not many manufacturers who master this process. Dongguan Jiaji Plastic Products Co., Ltd. has completely produced qualified plastic pepper balls through years of research and development.
