Injection molding method of embedded hardened pc sheet and anti-scratch hardened electronic product window

Abstract

The invention discloses an injection molding method for embedding a hardened PC sheet, which comprises the following steps: (1) preparing a hardened PC sheet, wherein one side of the hardened PC sheet is a hardened surface, and the other side is a PC surface, Described hardened surface is provided with color to be distinguished from PC surface; (2) prepares electronic product PC window injection mold, is provided with the groove that places the described hardened PC sheet of step (1) in this mold cavity; (3) The hardened PC sheet described in step (1) is placed in the mold cavity, the hardened surface of the hardened PC sheet is placed downwards, and the hardened surface is attached to the bottom of the mold cavity; (4 ) molded and injected with PC material to form a double-layer structure of anti-scratch and hardened electronic product window, the upper part is an injection-molded transparent PC layer, and the lower part is a hardened PC sheet, which completely covers the transparent PC layer. surface, the hardness of the hardened surface is the surface hardness of the electronic product window. The invention also discloses an anti-scratch and hardened electronic product window.

Description

technical field [0001] The invention relates to the technical field of plastic electronic product manufacturing, in particular to an injection molding method for embedding hardened PC sheets and an anti-scratch hardened electronic product window. Background technique [0002] In the past, PC injection molded materials with a surface hardness lower than 1HB were used as high-gloss or glossy surfaces for electronic product windows, which were easily scratched and difficult to protect. [0003] In addition, a better method is to make surface coating UV protective oil, but this method has high defective products and high cost. [0004] At present, sapphire glass is often used for transparent windows or colored windows. The hardness of sapphire glass is 9. Although it can resist abrasion, it cannot withstand strong impact. At the same time, some substances with the same or higher hardness, such as: grinding stone , sandpaper, nail files, granite surfaces, concrete walls and floo...

Problems solved by technology

[0002] In the past, PC injection molding with a surface hardness lower than 1HB was used as the high-gloss or glossy surface of the window of electronic products, which is easy to scratch and difficult to protect.

[0003] In addition, a better method is to make surface coating UV protective oil, but this method has high defective products and high cost

[0004] At present, sapphire glass is often used for transparent windows or colored windows. The hardness of sapphire glass is 9. Although it can resist abrasion, it cannot withstand strong impact. At the same time, some substances with the same or higher hardness, such as: grinding stone , sandpaper, nail files, granite surfaces, concrete walls and floors, etc. may scratch the surface, and the cost and production cost of sapphire glass is relatively high, so it is mainly used to make high-end watch mirrors and cannot Popularized into the products of smart wristbands or smart bracelets commonly used by ordinary consumers
