Pengde 3D curved tempered film adopts etching + cold carving technology, and uses Xuhong high-aluminum glass to etch first and then cold carve. It is a real whole piece of glass. The glass is first etched into a 3D concave surface by chemicals, and then the appearance and inner and outer arcs of the glass are processed by CNC precision engraving machine.

The advantage is that since the 3D concave surface is etched by chemicals, the entire 3D surface will be very flat and not physically damaged. When tempering, there will be no deformation. The exhaust performance of the finished glass film is very stable, and there will be no curling and unstable exhaust. This is also the reason for the high-end brand etching + cold carving technology. 3D combines the curvature of the mobile phone cover to completely wrap the edge of the screen, covering more comprehensively, not easy to get dust, and the surface is electroplated with fingerprint oil. It is wear-resistant for more than 10,000 times, and it can keep the hand feel smooth for a long time. AB glue is anti-static, automatic exhaust, and better fit.
