The processing method of plastic pepper ball grinding process is very different from other plastic products. The surface grinding effect of other plastic products is achieved by using molds, while plastic pepper ball products need precise grinding. How to grind the ground surface after the mold is released will also be ground off by the ball grinder.

The frosting process of plastic pepper balls is made by physical processing. After the plastic pepper balls are finely ground by a ball grinder, they are polished in a special machine for about 1 hour. Then, the plastic pepper balls are put into a special drum-shaped grinding wheel for rotary sanding. After about 2 hours, the plastic pepper balls are cleaned and dried, which is the finished frosted plastic pepper balls.
