Hard Anodizing and Clear Aluminum Anodizing

We offer free capacity at new automatic line for anodising of Al for following processes:
-> clear anodising of Al parts -5-20um
-> hard anodising of Al parts -10-80 um
-> dyeing of anodised parts - black colour.
-> hard anodising of Al parts + impregnation PTFE(3-5um)
-> chemical conversion coating type II. by MIL5541.
-> chemical etching and pickling of Al parts.

We offer custom services in Hard Anodizing, Clear Anodizing and black anodizing & PTFE(Teflon) penetrated hard anodic coatings.

The services are provided under quality management system according to ISO 9001:2008.

The modern industrial half-automated line with powerful cooling. The anodizing bath is Sulfuric acid and sealing is done in hot demi water.

Maximum dimensions of parts: 1300x1000x500 mm
