Plastic products are more and more widely used, so the surface quality requirements of plastic molds are also higher, and mirror polishing is often required. The role of plastic mold polishing not only increases the beauty of the workpiece, but also changes 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 the plastic bottle is transparent and has a glass texture. After using the polishing process, it can increase the transparency and make the surface more smooth and delicate. The specific operation steps are to use sandpaper to remove the surface defects of the plastic tube blank, and then use 3M pyramid sandpaper. Grinding with a dry mill and polishing with diamond paste, the products after these processes will be as shiny and transparent as glass, and these products are usually used for food packaging.
