Manufacturing process for aluminum-containing die-casting shell capable of anodic oxidation

Abstract

The invention provides a manufacturing process for an aluminum-containing die-casting shell capable of anodic oxidation. The die-casting shell is designed into two portions, one is an internal structural component, and the other is an exterior component which encircles the outer periphery of the internal component. Firstly, machine shaping is conducted on the exterior component, the exterior component is arranged in a die-casting mold, metal liquid is poured so that the exterior component and the internal component are casted into a whole to be the shell, and the anodic oxidation process is conducted on the die-casting shell. The manufacturing process for the aluminum-containing die-casting shell capable of anodic oxidation has the advantages of applying the technology of the anodic oxidation to the aluminum-containing die-casting shell, reducing the manufacturing procedures of CNC, saving the production cost, improving the product yield and the dimensional precision, and reducing the waste of aluminum alloy material, the equipment of CNC and the investment of human resources.
