(1) the abrasion resistance and hardness of the surface treatment of the product can be up to 4h-9h, easily realizing the test requirements of the mobile phone shell;

(2) the surface of the product is easy to be processed and fingerprint-proof, i.e., oil-repellent and water-repellent. The Angle of water drop can be measured to 107 degrees, which is of the same quality as glass and ceramic cover plate;

(3) composite material (PC+PMMA) : compared with glass material, it is easier to directly add dazzle UV texture decoration products on the material, and it can change the material and apply more colorful appearance effect; Moreover, it overcomes the problem that glass and ceramic materials are easy to fall and break.

(4) composite material (PC+PMMA) : compared with the internal decoration technology of IMD/IML/IMT injection mold, the product is easy to form and can be designed to modify the required thickness flexibly, so that the product can be more ultra-thin; And completely overcome the IMD/IML process in the injection molding easy to produce peeling no adhesion and product deformation warping headache;

(5) composite material (PC+PMMA) : the product development and mold opening cycle is short, the production capacity is high, the cost performance is high, the corresponding product unit price is close to IMD/IML process, is 1/3 of the glass process, 1/8 of the ceramic process, 1/3 of the hardware process.

After comparison, it can be found that, with the development of the market and application, glass, ceramics, metal and traditional plastics can no longer meet the demand of some mobile phone markets. So, this has promoted the rise of composite cell phone covers. In addition, in addition to the cost, processing, performance can also meet the market requirements. Therefore, 3D high-pressure molding process of composite plate is a low-cost alternative to glass coating process!
