The conventional manufacturing process of plastic pepper balls is to polish the surface of the ground plastic pepper balls, but some customers with special needs need frosted plastic pepper balls, and it is much more difficult to process frosted plastic pepper balls than polished plastic balls. The specific processing methods are described below.The pre-processing methods of polished plastic pepper balls are almost the same, all of which require injection molding of rough plastic pepper balls, air removal of rough plastic pepper balls, rough grinding and fine grinding. Polishing plastic pepper balls is carried out after fine grinding, while grinding plastic pepper balls after fine grinding is carried out. The difficulty of grinding is that the grinding effect required by customers needs to match the corresponding grinding materials according to the actual situation. There are many kinds of roughness on the surface of frosted materials, and there are also many kinds of materials. When choosing frosted materials, you can only make a rough judgment according to your eyes, and then use the selected frosted materials to grind plastic pepper balls. The processed frosted plastic pepper balls should also confirm the grinding effect to customers. If the effect required by customers cannot be achieved, it is necessary to re-select frosted materials for grinding test. Therefore, the grinding of plastic pepper balls is a very labor-consuming and time-consuming job.
