Electroplating El ec tr op la ti ng

• Our electroplating facility is one of the biggest and most sophisticated in the area. With more than a hundred programs, we have the possibility, to electroplate almost every aluminium part with it's optimal program.

Anodising

Decorative and Hard Surface in Different Colours: • Clear • Deep black (MLW) • Turquoise blue (PLW) • Brand red (ML) • Gold-Yellow (L) • Blue (G) • Turquoise green • All colours RoHS compliant Process: With the anodic oxidation hard and wear-resistant aluminium surfaces are produced with sulfuric acid electrolytes. These oxide coatings improve not only the corrosion resistance, but can also give a decorative finish to components if a coloured dye is used. The layer thick- nesses can be from 5 to 30 µm. Anodic oxide coatings are not electrically conductive.

Passivation

Corrosion Protection, Electrically Conductive: • Clear (RoHS compliant) • Yellow Process: With the passivation procedures by chemical action, thin layers (approx. 0.1 to 0.5 µm) result. These are yellow during the yellow chromate finishing and with the clear passiva-tion finishing transparent. These layers are corrosion resistant and offer an outstanding adhesion for lacquer and powder coatings. Due to the small layer thicknesses the sur-faces remain electrically conductive. Use Elma’s front panel service not only for electroplating, but also for machining, silk screen printing, painting and assembling.
