Plastic mold processing in the polishing

Mold polishing Do not use the finest whetstone, sandpaper, abrasive polishing paste, that can not be thrown away the rough lines. The living surface polished in that way looks very bright, but with the sideways, the rough lines appear. Therefore, first from the coarse whetstone, sand paper or grinding polishing paste, and then for a relatively small whetstone, sandpaper or grinding polishing paste, and finally with the finest grinding polishing paste polishing. This looks like more trouble, more processes. In fact, not slow, a process after another, in front of the rough grinding of the grinding process, and then the following process, will not rework, go down once you can make the mold finish to meet the requirements. Plastic mold

Here are some ways to introduce polishing: 1, magnetic grinding polishing

Is the use of magnetic abrasive in the formation of abrasive brush under the action of the magnetic field on the workpiece grinding. This method of processing efficiency, good quality, easy processing conditions, good working conditions. With a suitable abrasive, the surface roughness can reach Ra0.1μm. 2, the basic method of mechanical polishing

In the plastic mold processing said polishing and surface polishing required in other industries are very different, strictly speaking, the mold polishing should be called mirror processing. Not only does it have high demands on the polishing itself, but it also has high standards for surface smoothness, smoothness and geometric accuracy. Surface finish generally requires only a shiny surface. Mirror processing standard is divided into four: AO = Ra0.008μm, A1 = Ra0.0
