The role of plastic mold polishing not only increases the beauty of the workpiece, but also can improve the wear resistance and corrosion resistance of the material surface. At the same time, it can make the plastic products easy to demould and reduce the production injection cycle. Therefore, the role of plastic mold polishing is a very important process in the mold manufacturing process.
For example: the appearance of a plastic bottle is transparent and has glass texture. After polishing, the transparency can be increased and the surface is smoother. The specific operation steps are as follows: first, remove the surface defects of the plastic tube blank with sandpaper, then grind it with 3M pyramid sandpaper by dry mill, and finally finish polishing with diamond paste, After these processes, the products will be as transparent as glass. These products are usually used for food packaging.
