Industrial aluminum profiles are widely used and can be divided into general industrial aluminum profiles and precision-machined industrial aluminum profiles.
1. General Industrial Aluminum Profiles – Aluminum templates, solar frames, battery trays, etc.
2. Precision-Machined Industrial Aluminum Profiles – Materials for aerospace, automotive decorative parts, automotive components, and 3C aluminum materials.
1. Solar Frames: In 2023, solar profiles increased by 30.8%, and the common surface treatmentsinclude matte electrophoresis and anodizing.
2. Aluminum Formwork: They are construction molds made of aluminum profiles, consisting of a system with three parts: aluminum panels, supports, and connectors.
3. Battery Trays: Battery system housing is a key component of electric vehicles. It can be made from extruded aluminum profiles or sheet metal. The surface treatment include cathodic electrophoresis and PVC coating.
4. Battery Enclosures – Insulating Powder Coating: Insulating powder coating layers are widely used in the battery field of new energy vehicles, offering optimal protection and support, making them an ideal companion for electric vehicles.
a. Electronics
Computer Casings and Aluminum Alloy Phone Frames: Computer casings and phone mid-frames (or back covers) undergo surface treatments such as anodizing, powder coating, painting, and micro-arc oxidation.
b. Automotive Lightweighting
● Passenger Car Aluminum – Sunroof Rails:
Sunroof rails typically undergo anodizing with hot water sealing treatment. Decorative surfaces may also use anodizing combined with matte electrophoresis.
● Passenger Car Aluminum – Roof Racks:
Roof racks require properties such as wear resistance, weather resistance, and self-cleaning functionality. Therefore, they are usually treated with anodizing and hot water sealing or anodizing with matte electrophoresis. Some are also treated with painting.
● Passenger Car Aluminum – Automotive Bumper Beams:
To align with the passenger car's exterior design, the surface treatment of bumper beams matches the car body finish.
