Aluminum profile surface defects brushing and cleaning machine is an effective tool for burrs, granules, marks and scratches removal of aluminum profile before anodizing, powder coating and wood grain effect sublimation process.
During the extrusion production process, the fine granules adsorbed on the surface of aluminum profile belong to a kind of surface defect.
It only has a slight hand feeling, and it is difficult to find it without careful observation or hand touch before anodizing and powder coating process.
However, it seriously affects the surface appearance of anodized and powder-coated aluminum profiles, reduces production efficiency and yield, and is one of the defects that are not allowed to exist in high-grade decorative aluminum profiles.
The burrs of the aluminum profile is caused by local tearing due to the low strength at the exit of extrusion and the friction between the surface of the aluminum profile and the die land of mold.
The main reasons for the formation of these burrs are:
The quality of the aluminum billets, the extrusion process, the influence of the aluminum profile mold, and the dust, water, oil, etc. in the air are strongly attached to the surface of aluminum profile.
Some extruded aluminum profiles have granular burrs on the surface, which cannot be found before the anodizing and powder coating.
Analysis of the causes of granular burrs adsorption
There are four types of granular burrs on the surface of extruded aluminum profiles:
1. Air dust adsorption, dust, aluminum scraps, oil and water produced by aluminum billet heating furnace condense into particles and adhere to the surface of the extrusion aluminum profiles.
2. Impurities in aluminum billets, such as metal inclusions and non-metallic inclusions left by insufficient refining.
3. Dust adhesion in the aging furnace.
4. The defects in aluminum billet and the β-phase AlFeSi in the composition precipitate at high temperature, which reduces the plasticity of the metal and the tensile strength, resulting in granular burrs.

Besides of Measures to reduce granular burrs from the extrusion processes and factory management, aluminum profile surface defects brushing machine can be applied for granular burrs removal
It can be applied before anodizing, powder coating and wood grain effect sublimation process
It can remove the granular burrs effectively and brighten aluminum profile in high efficiency. 
Minimize or avoid the quality problem and reduce NG rate and increase your profit.
In order to reduce the granular burrs on the surface of aluminum profiles, it is necessary to strictly control the production process and analyze its formation mechanism.
At the same time, continuous observation and analysis in extrusion production practice, summarizing its causes, and taking timely measures are effective means to reduce or eliminate the occurrence of such defects.
