What surface treatments do aluminum alloy die-casting have?

Anodizing: The surface of extruded aluminum alloy profiles is not very corrosion-resistant. It must be surface treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum.
Electrophoretic painting: The surface of electrophoretic painted profiles has a soft luster and can resist the erosion of cement and mortar acid rain.
Powder electrostatic spraying: Powder electrostatic spraying profiles are characterized by excellent corrosion resistance, and their resistance to acid, alkali and salt spray is much better than oxidation colored profiles.
Titanium plating and titanium gold plating process: The titanium gold plating process for aluminum profiles is a coating technology. It adds pre-plating and electroplating process steps on the basis of the conventional titanium plating process. The pre-plating process is to place the activated plated parts in salt and Chemical treatment in an aqueous solution of hydrochloric acid to create colorful effects.
Wood grain transfer: Vacuum wood grain coating technology is to transfer the wood grain to the surface of the workpiece through thermal transfer after the metal product is electrostatically sprayed. Not easy to fade, the wood grain is realistic, which improves the quality of the product.
Note: Since aluminum is all made of electrolytic aluminum, the surface treatment method is basically the same as the previous two articles, with minor differences. However, it should be noted that the molding methods of these three processes result in different surface effects of the initial products obtained, and the selected surface treatment effects are also different.
