IV. Surface treatment
1. Anodizing after sandblasting or brushing
2. Electrophoretic painting
3. Powder electrostatic spraying after polishing, fluorocarbon spraying
4. Electroplating after mirror polishing
5. Wood grain heat transfer
6. Polymer PVC coating
V. Aluminum profile
Aluminum profile is an aluminum tube material with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods.
The molding process mainly includes 5 processes:
Casting, extrusion, cutting, CNC washing and cutting, surface pretreatment, and coloring.
Titanium plating and electrophoresis processes are the most expensive, followed by wood grain thermal transfer, anodizing, and finally spraying. The specific price is subject to the manufacturer's quotation.
The main uses of aluminum profiles are as follows:
1. Architectural aluminum profiles (doors, windows, curtain walls)
2. Radiator aluminum profiles
3. General industrial aluminum profiles: mainly used in industrial production and manufacturing, such as automated machinery and equipment, skeletons, etc., which can be customized by mold opening.
4. Rail vehicle structural aluminum alloy profiles: mainly used for rail vehicle body manufacturing.
5. Decoration aluminum profiles, made into aluminum alloy face frames, framed various decorative paintings.
6. Appearance aluminum profiles, mainly used in home appliances or communications industries, such as mobile hard drives, mobile power supplies, televisions, monitors, etc. for internal structure and appearance decoration.
