For aluminum alloy die-casting products, the surface treatments generally include: powder spraying (powder spraying), paint spraying, oil spraying, oxidation, sandblasting, electroplating, etc. According to the thickness of the product surface treatment, the finish is different.
After the powder coating is baked, leveled and cured at high temperature, it enters the final coating with different effects (different types of powder coating effects); the effect of powder spraying in mechanical strength, adhesion, corrosion resistance, and aging resistance is better than the coating process. The cost is also the same as the painting effect.
Powder coating is roughly divided into outdoor powder and indoor powder. The texture can be adjusted to various effects, such as smooth, fine sand, foam, etc.
The real baking paint process is to use aluminum alloy phosphating spraying and spraying after baking. Such a coating is not only corrosion-resistant, bright and wear-resistant, but also not easy to fall offv
Aluminum alloy die-casting surface treatment
(1) Degreasing; 2 Water; 3 Derusting; 4 Washing; 5 Watching; 6 Washing; 7 Phosphating; 8 Washing; 9 Washing; 10 Drying;
(2) The purpose and importance of pretreatment:
The purpose of pretreatment is to get a good coating, because the above stamping parts will have oily grease, oxides, rust spots, dust, rust spots and rust during the manufacturing, processing, handling, and storage. The impact on the surface will be directly affected if it is not removed. The performance and appearance of the coating occupies a very important position in the painting process.The purpose of pretreatment is to get a good coating, because the above stamping parts will have oily grease, oxides, rust spots, dust, rust spots and rust during the manufacturing, processing, handling, and storage.

(3) Pretreatment significance:
Coating pretreatment, coating and drying are the three main processes of the coating process, of which pretreatment is the basic process, covering the entire coating
The quality, service life and appearance of the coating have an important influence
After degreasing, derusting, phosphating and other processes, the surface of the workpiece is clean, uniform and free of oil
Aluminum alloy die-casting oxidation
Aluminum alloy surface oxidation, suitable for conductive oxidation, aluminum or aluminum profile, suitable for anodic oxidation.
Aluminum alloy oxidation color is generally natural color, sky blue
