The invention discloses a high-strength wear-resistant aluminum mobile phone middle frame and a processing technology thereof. Including the following steps: step 1: melting and die casting the aluminum alloy raw material, forging, CNC rough milling and grinding, to obtain the middle frame A of the aluminum mobile phone; step 2: subjecting the middle frame A of the aluminum mobile phone to alkali washing, pickling, and ultrasonic hot water in sequence The processing steps are surface treatment; nano-injection, annealing; CNC fine milling; obtaining aluminum mobile phone middle frame B; step 3: placing the aluminum mobile phone middle frame B in an electrolyte for hard anodizing; surface sealing; Strength and wear-resistant aluminum mobile phone middle frame. Beneficial effects: In this technical solution, the combined treatment of alkali washing, acid washing and ultrasonic hot water treatment enhances the bonding strength of the polymer after injection molding and increases the yield. The uniformity of the surface reaction is increased by adding titanium sol to the electrolyte during the hard anodizing process, and the surface hardness and wear resistance are enhanced in synergy with other components and the ozone pre-dissolution step. |
