CNC Precision Machining PMMA Parts performs good in electrical insulation and machinability. The transparency of CNC machining PMMA parts can be 95% after polishing, and PC is incomparable. There are transparent materials among PC too, but the transparency is not as good as PMMA.
During the machining, the cutter will make the surface of CNC machining PMMA parts become fuzzy. Polishing by sandpaper, it can be transparent. If you want semi-transparent in tawny or grey, the whole PMMA workpiece need to be soaked into the liquid with relevant color. If you need only a small window on the surface of workpiece, and the rest is opaque, then the rest area should be painted with shading coating.
After painting, the surface of CNC machining PMMA parts can be sealed with various pattern or letter by laser. With laser carving machine and shading coating, you can realize the effect that you want to present. The instrument panel, control panel of electronics and electric appliance are all made by this. All you need is providing a file marking the transparent area and opaque area. The back side of the transparent area should be polished until it is transparent too.
