Process of matt finish

2022-03-09

Sandblasting is a common process before the surface treatment of aluminium profiles. The aim is to make the surface of aluminium profiles to be rough and matt finish. Normally , sandblasting processing will not affect the appearance of aluminium.

Basis on compressed air as the power and becoming a high speed inject beam, and inject the emery to the surface of the profiles in different angles.Then physical changes occurring on the surface to meet the quality.


1.Mill finish like below,and was put at the right side.




2.After the physical changes ,they come out at the left side


3.There are some sands on the surface, then they would be taken out into the ash-bin.




4)The surface is now smooth and good.



5)Anodized Process.





Advantage:

1.It’s easy to clear the dirt one surface.

2.It can cover the grain on surface,to make it smooth and flat.

3.The mechanical properties of aluminum profiles’ surface are improved, so that the wear resistance is also improved.

4.Improve the adhesion,prolong the durability of the coating, and also good for decoration.

5.It’s not obviously when scratched.
