With the large-scale penetration of OLED screens in 2018, the 3D glass industry has seen overall high growth. Especially after the OLED production capacity is completely released, the demand in the mobile phone field alone can make the overall industry growth rate exceed 30%. Since 2019, more and more smart phones have begun to use curved glass as screen covers. At present, 3D curved glass has become an important choice for many mobile phone manufacturers to pursue product differentiation.
Nowadays, the domestic mobile phone manufacturing technology is constantly upgraded, and manufacturers' pursuit of product aesthetics is increasing. 3D curved glass is gradually popularizing and covering all kinds of product screens. 3D curved glass, as a new material for mobile phone casings, will solve the technical problems of signal shielding and poor heat dissipation that have always existed in mobile phone backplanes, and will become the optimal choice for backplanes.

Tool performance
Indirectly affect 3D curved glass processing
Hot bending graphite mold is widely used in 3D curved glass processing, which has the advantages of improving the surface finish of glass, reducing glass stress, and reducing overheating and other phenomena. However, the graphite mold processing yield is low and the cost is high. According to data, the graphite mold processing product yield in the industry is only 55% to 65%, and the tool wear is serious. How to improve the mold yield depends largely on Tool performance.
3D curved glass mold
In the processing of graphite molds, CVD diamond-coated cutting tools have become the best choice for graphite processing due to their light weight, high strength, fatigue resistance, corrosion resistance and strong designability. Their service life is hard alloy. 8 ~ 10 times of CVD, the allowable cutting speed of CVD diamond coated tools is 2 ~ 3 times higher than that of cemented carbide tools. The cutting edge is sharp and consistent, and the friction factor is low. High-speed and high-precision machining of graphite molds.

Makes metal frame processing difficult
With the popularization of 3D curved glass, another part of the mobile phone has changed, that is, the metal middle frame. Under the "extrusion" of 3D curved glass and the back plate, the metal middle frame needs to bear more external pressure with less material, while the previous aluminum alloy materials have gradually failed to meet the needs of manufacturers.
Whether the iPhone XR last year used Apple's special alloy material, or Xiaomi's concept machine MIAα this year uses aerospace-grade titanium alloy materials, the application of these materials has also raised the complexity of the tool's complex metal processing capabilities and accuracy Requirements.

Whether it is low-yield and high-cost graphite mold processing or alloy middle frames with higher material requirements, tool companies need to continuously improve product quality, enrich product types, and respond to the changing needs of 3C industry processing in a timely manner. Tool companies are ready ?
