CNC Machining service PMMA is the abbreviation of Polymethyl Methacrylate. It is also named as Acrylic.PMMA is also a frequently used plastic material in prototype manufacturing because of its excellent transparency. If your prototype need very transparent effect, PMMA material is the only choice. Because the transparent effect of PC material is much inferior to PMMA material. The only weakness of PMMA material is bad tenacity. It is easy to break apart if you have any structure with button placement. highly transparent PMMA prototypetexture finishing transparent PMMA prototype The natural color of PMMA material is transparent, but PMMA surface would become indistinct and untransparent after CNC machining. It need to be polished with abrasive paper and abrasive compound to become transparent effect again, which is related with time cost of prototype manufacturing. Therefore, in order to help you to save manufacturing cost, Leecheer suggests you to make documentation with image and text to explain high transparent area, which can save unnecessary manufacturing time. After PMMA machining, PMMA prototype would become high transparent effect again after polishing. If the surface of PMMA prototype is sprayed with tinted but transparent paints or the whole PMMA prototype is soaked in liquid with different colors, you can get the transparent effect with colors. For example, all kinds of different red colors of automotive lightings are made by this method. Another surface effect of PMMA can be shown is that spraying lightproof paints on PMMA surface, then carving out lightproof paints with laser engraving according to different patterns or texts to reach the light transmitting effect you want. The control panels of many household appliances are made by this method. art text pervious to lighttransparent effect with colors The reasons to choose Leecheer Prototype Company The Video of quantity evaluation given by England customers About delivery time,our company choose FedEx intl.
