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.
