Anodising is usually referred to as hydrochloric acid anodising if it is not pointed out in particular. Then, you understand a good number of aluminum profile anodizing production and processing common problems?
1, aluminum profile selection, hard aluminum bar
Before solving the whole process of aluminum alloy profile, raw materials should be taken with hard aluminum alloy profile aluminum bar, and robotic aluminum profile in the production and manufacturing processing method used in the mounting fixture needs to maintain smooth and excellent electrical conductivity.
2、Before air oxidation, jig removal
Before the anodising of the aluminium alloy profile, the jigs previously used are cleared. The residual air oxidation film on the surface of the jig is eliminated to ensure better contact characteristics with the aluminium bar when it is in use.
3. Total conductive area during the production process
During the production of anodised aluminium alloy profiles, the total conductive touching area of the fixture should be ensured and the scratches on the fixture should be as small as possible.
4、Air oxidation aqueous solution, temperature range
The temperature range of the aqueous hydrochloric acid anodising solution used for anodising aluminium is 15 to 25°C.
5、Cooling equipment, air compression and mixing
The production process of anodised aluminium should be equipped with cooling equipment, and the disposal method of air compression mixing should be chosen.
