The manufacturing technology of plastic pepper balls is very different from that of paraffin pepper balls. First, paraffin pepper balls are produced by casting technology, while thermoplastic pepper balls are produced by injection molding technology. Although they are both called pepper balls, they are quite different.The plastic raw material used for paraffin pepper balls is phenolic resin or unsaturated resin. In fact, the production of this kind of paraffin pepper balls is similar to glue. After several chemical raw materials are mixed in a certain proportion, the mixed resin is cast into a paraffin pepper ball mold. After the cast paraffin pepper ball is molded and solidified in the mold, it is a semi-finished paraffin pepper ball. Generally, paraffin pepper balls do not need grinding treatment. Paraffin pepper balls are mainly made of ornaments and handicrafts and do not need precision. Therefore, semi-finished paraffin pepper balls only need polishing.
