CNC Machining PMMA Prototype
PMMA is the best choice for transparent prototype. PC is incomparable to PMMA. There are transparent materials among PC too, but they have to be fumigated to be transparent, and the effect is not as good as the PMMA. CNC machining PMMA prototype can be totally transparent after burnishing, and the transparency can be 95%.
PMMA, known as Acrylic, is more transparent than PC. Purple glimmers dimly in PC. In terms of temperature tolerance, PC is superior. It will not deform in 130℃. However, CNC machining PMMA prototype will deform in 90℃, and the working temperature is below 70℃。
CNC machining PMMA prototype can be treated with spraying, electroplate, silk screen, laser carving and so on. Because of the fragile and scratchy of PMMA, Bordersun use doble packing to protect it. The first layer is a ply of special paper, the oily side and the smooth side. The oily side will be used to wrap the prototype. And the second layer is EPE. It can prevent the packing materials stick to the prototype, which will result the respray.
