Abstract
The invention provides a processing technique of a cellphone shell with metal luster. The processing technique includes the steps of S1, performing compression molding; S2, performing stamping; S3, performing primary CNC (computer numerical control) machining; S4, performing T treatment; S5, performing injection molding in a nano mold; S6, performing secondary CNC machining; S7, performing surface treatment, to be specific, performing a, polishing, b, shot-blasting, c, degreasing, d, washing, e, electrolytic polishing, f, washing, g, silicon removal aiming to decrease silicon content of the polished surface of the cellphone shell, h, neutralizing, i, chemical polishing, and j, electrophoresis or combination of anodic oxidation and coloring, aiming to impart metal luster to the polished surface of the cellphone shell. The compete cellphone shell is made through the steps S1 to S6, the silicon content of the polished surface of the cellphone shell is processed, the cellphone shell never produces compounds of intervals such as Al-Mg-Si-Fe during following anodic oxidation, defects such as oxide film darkening, bluing or milky-whiting are avoided, and the metal-lustered cellphone shell is manufactured through the complete process.
Description
technical field [0001] The invention belongs to the field of mobile phone case processing technology, and in particular relates to a mobile phone case processing technology with metallic luster. Background technique [0002] The mobile phone shell is made of metal materials and combined with anodizing and other treatment processes, which can make a very delicate metal appearance effect. Now the metal processing usually used is aluminum alloy CNC processing, but all of them are processed by CNC, which leads to long CNC processing time and complicated procedures. In turn, the cost is too high. In order to solve the problem of long CNC processing time, the industry adopts die-casting molding process to complete it. However, since the commonly used mobile phone materials for die-casting molding are ADC3-ADC12, etc., the content of Si, Mg, and Fe are usually low. High, when doing anodic oxidation, interval compounds such as AL-Mg-Si-Fe will be formed, which will make the oxide fi...
