What Are the Post-processing Procedures for Aluminum Die Castings?

The post-processing procedures of aluminum die-castings are crucial to improving product quality and performance, mainly including CNC machining, surface treatment and assembly.

CNC machining: Aluminum die castings are precisely processed through cutting, drilling, milling, grinding and other processes.

Drilling, tapping: Use special tools to complete drilling, tapping and other operations on aluminum die castings to meet specific connection requirements.

Milling: Use a milling cutter to remove part of the material on the surface or other positions of the aluminum die casting to achieve the processing and precision improvement of the part shape.

Cutting: With the help of CNC machining equipment, the aluminum die casting is precisely cut into the specified geometric shape.

Grinding: Use grinding machines, grinders and other equipment to polish and grind the surface of the aluminum die casting to achieve the finish and texture required by the design.

Surface treatment: It can significantly improve the surface color and corrosion resistance of the parts, enhance the structural stability and mechanical properties.

Anti-corrosion treatment: Die-castings are immersed in acid solution to form an anti-rust film, which effectively prevents oxidation and improves corrosion resistance.

Painting: Spraying a layer of paint on aluminum die castings through painting equipment not only enhances the decorativeness and aesthetics, but also makes the surface of the castings less susceptible to contamination.

Coating film: Through chemical reactions, a metal film is generated on the surface of die castings, which plays an anti-corrosion, wear-resistant and protective role.

Assembly: Assemble aluminum die castings in order to make products with specific functions.

Cold assembly: Assembly is completed by simply tightening components such as bolts or nuts.

Hot assembly: Assembly is achieved with the help of hot processing processes such as high-temperature fusion or welding.

Laser welding: Multiple aluminum die castings are welded into a whole using laser welding technology.
