Mold polishing has two purposes; one is to increase the smoothness of the mold, so that the surface of the product out of the mold is smooth, beautiful and beautiful, and the other is to make the mold easy to demold, so that the plastic is not stuck on the mold and cannot be removed. .
Do not use the finest whetstones, sandpaper, and polishing pastes at the beginning of the mold polishing process, as it is not possible to throw off rough lines. The polished surface that looked so polished looked bright, but as the side shot, the thick lines appeared. Therefore, first grind it from coarse whetstone, sandpaper or polishing paste, then use finer whetstone, sandpaper or polishing paste for polishing, and then polish with the finest polishing paste. This may seem like a lot of trouble and there are many processes. In fact, it is not slow, and the processes that follow one another will be used to polish the rough processing lines before proceeding with the following processes and will not be reworked. Once you walk down, the smoothness of the mold can be achieved. .
