Everything you need to know about extruded aluminum profile

This article mainly introduces how to extrude aluminum profiles and the solutions for scratches on the surface of extruded aluminum profiles.
Surface pretreatment
Use chemical or physical methods to clean the surface of the profile to expose the pure matrix to facilitate obtaining a complete and dense artificial oxide film. It is also possible to obtain a mirror or matte surface by mechanical means.
Sealing
The pores of the porous oxide film formed after oxidation are closed to enhance the anti-pollution, corrosion resistance and wear resistance of the oxide film. The oxide film is colorless and transparent. Using the strong adsorption of the oxide film before sealing, some metal salts can be adsorbed and deposited in the film pores to make the appearance of the profile appear natural.
Frosted aluminum profile avoids the shortcomings of bright aluminum profile that will cause light interference in certain environments and conditions in architectural decoration. Its surface is as delicate and soft as brocade, which is very popular in the market, but the existing matte The material must overcome the uneven sand on the surface, and the lack of pattern patterns can be seen.
In addition, the monotonous silvery white and brown color can no longer satisfy the good coordination of architects with exterior wall decorative tiles and exterior wall latex. The new stainless steel color, champagne color, golden yellow, titanium gold, red series, etc., plus colored glass can make the decorative effect with the icing on the cake. These profiles must be chemically or mechanically polished and then oxidized for the best results.

How to deal with scratches in extruded aluminum profiles
Most of the scratches on the surface are caused by foreign matter stuck in the mold or rough machining at the empty knife. There is also a raised scratch on the corner of the product, which is caused by cracks in the extrusion mold. Scratches or scratches are mainly due to the fact that there are hard objects on the cooling bed when the product is transported from the slide out to the finished sawing table and scratched the product, and some are scratches generated during loading and handling. The scratches are aluminum extrusions. Common surface defects in the pressing process.
Elimination method of extruded aluminum profile
1. The working belt of the extrusion die should be processed smoothly, and the empty cutter of the extrusion die should also be processed smoothly.
2. When installing the mold, check carefully to prevent the mold with small cracks from being used. Pay attention to the fillet radius when designing the mold.
3. Frequently check the cooling bed and finished product storage table to prevent hard protrusions from scratching the product.
