Three-injury repair process of high-brightness oxygen-polished metal mobile phone back cover

Abstract

The three-injury repair process of the metal mobile phone back cover of the high-brightness oxygen polishing surface of the present invention is processed through the following steps: 1. Allocate repair agent, get 20ml of surfactant, 15ml of alkane solvent, 30ml of grinding agent, 10ml It is obtained by mixing aliphatic hydrocarbon solvent and 25ml metal polish; 2. Use sandpaper to polish the three-damage area on the surface of the metal mobile phone back cover with high-brightness oxygen polishing. Spread the surface evenly; 4. Polish the repair piece with wool until it meets the standard high-gloss gloss effect. Adopting the three-injury repair process of the present invention can effectively remove and repair 90% of three-injury defective products, reduce the three-injury defect rate of high-brightness oxygen-polished metal mobile phones, and greatly improve the shipment of high-brightness oxygen-polished metal mobile phones Quantity, to avoid the problem of matte surface when the three-injury repair of the high-brightness oxygen polished metal mobile phone back cover is carried out by the traditional metal repair process. At the same time, it has the advantages of simple process steps, low repair cost and fast repair speed.

Problems solved by technology

However, the existing high-gloss metal mobile phone back cover needs to be transported in different workshops or different processing equipment during the production process, or due to improper operation, etc., the surface of the high-brightness mobile phone back cover may be easily scratched, scratched or bruised. Minor injuries, the so-called three injuries, that is, there are dents on the surface of the back cover of the mobile phone

The three-injury defect rate of the existing high-brightness oxygen-polished metal mobile phone back cover reaches 33.75%, and the manufacturers of the mobile phone back cover do not have the technology to repair the three-injury, thus resulting in high-brightness oxygen-polished metal The shipment rate of the back cover of the mobile phone is very low, which undoubtedly makes the selling price of the high-brightness oxygen-polished metal mobile phone high.
