Micro-nano structured textured mold

The microstructures with submicron-level profile accuracy and nanometer-level roughness are fabricated on the 3D surface, and the mobile phone backplane with diffractive optical microstructure is mass-produced by precision injection molding. Compared with the traditional lamination process, the textured injection mold can shorten the process, greatly improves the quality, add the logo and anti-counterfeiting information, and eliminate the screen printing or laser carving process.
