Benefits of technology

This technology allows for creation of highly durably sized plastic parts that fit together well when used in electronics devices like smartphones or tablets. These plates consist mainly of solid gold crystal grains surrounded by liquid metal around them. They expand slightly during formation without losing their original shape after they cool down from room temperature. Additionally, this design makes the manufacturing process faster while maintaining good appearance characteristics such as transparency, reflectivity, color clarity, abrasiveness, impact resistence, weldability, etc., compared to other materials commonly found in previous designs. Overall, these technical features enhance the overall functionality and lifespan of electronic components.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the durability and performance of sintered ceramics (SCA) materials for various applications such as display devices or touch panels on electronics equipment.

example

[0051] 1. Sapphire sheets can be processed by blanking, grinding, polishing, cleaning and other processes.

[0052] Oriented slicing is used when cutting the processed product, and cutting along a certain crystal direction can significantly reduce the phenomenon of large chipped corners when the product is cylindrically ground; the polishing pressure is 0.05Mpa to 0.21Mpa, and the surface of the product is polished with this range of pressure No defects, less scratches, increase product yield.

[0053] The uniform force applied during grinding can reduce the incidence of small chipped corners of the sapphire sheet; the grinding of the sapphire sheet is preferably carried out at a constant temperature. When grinding, the sapphire sheet 1 is first ground so that the outer side is higher and the inner side is lower, so that the product after grinding tends to be flat, and the yield rate of product grinding is increased. The thickness of the sapphire sheet 1 is 0.6mm-1.5mm.

Abstract

The invention discloses a method for making a liquid metal waterproof shell, comprising the following steps: a, providing a sapphire sheet, and machining the side of the sapphire sheet into a shape suitable for being combined with an injection molding material; b, putting the sapphire sheet in the cavity of a mold, injecting liquid metal into the cavity of the mold, and making the liquid metal filling the cavity surround the side of the sapphire sheet, wherein the filling shape of the liquid metal is the shape of the peripheral part of a waterproof shell to be formed; and c, shrinking, solidifying and shaping the liquid metal at a predetermined rate to make the liquid metal combined with the side of the sapphire sheet. The sapphire material and the liquid metal are integrally molded, so that the product has no gap and has high waterproof, dustproof and shockproof performance, and a narrow-bezel screen can be realized.
