A Brief Discussion on Aluminum Alloy Die Casting Powder Spraying Process

　　Aluminum alloy die-casting parts have the characteristics of thin and fine walls, light weight, corrosion resistance, and are loved by a large number of customers. There are many surface treatment methods for aluminum alloy die-casting, such as powder spraying, baking paint, sandblasting, oxidation, etc. Next, we will introduce the powder spraying process to everyone.

　　Powder spraying is an economical and practical process, which has better effects than spray painting and lower costs than spray painting processes with the same effect. Powder spraying is a kind of powder coating, which has various colors and effects, and can enhance the mechanical strength, adhesion, corrosion resistance, aging resistance and other properties of die castings. The general process of powder coating for aluminum alloy die-casting parts is to first evenly spray the powder coating onto the surface of the die-casting parts through the powder spraying equipment. Under the effect of static electricity, these powders will adsorb on the surface of the die-casting parts, and then the die-casting parts will be baked and cured at high temperature to complete the process.
