The finished industrial aluminum profiles have a beautiful appearance and are highly resistant to dirt. However, if oil stains are applied, they can be troublesome to clean. When assembling products, we need to use different specifications of industrial aluminum profiles based on different load-bearing capacities, and utilize matching aluminum profile accessories without the need for welding.
1. Provide excellent appearance conditions and enhance the quality of surface finishing
Nowadays, a large number of aluminum profile finished products and household daily necessities are widely used, and a significant portion of them mainly consist of aluminum sand castings and die castings. The surfaces of these castings are rough and uneven, and we need to use machinery to process them, so that they can have a flat and smooth surface, providing excellent conditions for future anodic oxidation and chemical oxidation surface treatments. This can enhance the quality of surface finishing.
II. Improve product grade
Although the extruded industrial aluminum profiles and aluminum plates already have a smooth surface during the manufacturing process, these aluminum finished products usually do not undergo mechanical pretreatment before anodizing. However, with the progress of society, users have raised higher requirements, favoring polished surfaces or "matte" or "satin" surfaces. The use of mechanical polishing or buffing for extruded industrial aluminum profiles can completely eliminate defects such as extrusion marks, and even achieve a mirror-like bright surface. If sanding belts, sandblasting (shot blasting), or brushing are used for treatment, a matte or frosted surface is produced. After other surface finishing treatments, the ultimate quality of the product is greatly improved, and the basic product can be upgraded to a high-end product.
III. Reducing the impact of welding
Aluminum finished welding parts are widely used in industry. Due to the influence of high-compliance solder during welding, the microstructural organization of the welding area often undergoes changes, resulting in varying surface colors. Mechanical pretreatment may help reduce the impact of welding.
4. Achieving decorative effects
When crafting aluminum artworks and household goods, many require elegance and delicacy. Through unique mechanical methods such as sanding and brushing, we achieve decorative effects like linear patterns on the aluminum pieces.
V. Obtain a clean surface
After undergoing mechanical pretreatment, the finished industrial aluminum profiles will be free of oil stains and rust, with a high-quality color and luster, fully showcasing the clean surface of the aluminum substrate.
