Founded in 1949, Coloral SA is a family business active in subcontracting.

Coloral comes from Coloration de l'aluminium, the company's historic activity with over 65 years of experience in the field. The technique used to color aluminum is called Anodizing, Eloxing or Anodic Oxidation. It involves the surface transformation of aluminum into aluminum oxide. The aluminum oxide layer is porous, and by immersing the oxidized parts in a dye bath, the layer absorbs the dye by capillary action. As aluminum oxide is a ceramic, it gives treated parts greater hardness as well as improved corrosion resistance.

Wishing to provide its customers with ever more comprehensive solutions, Coloral SA has diversified into machining since the 1980s. Substantial investments have been made in this field over the last ten years, and the company now boasts a machine park of around ten CNC lathes, two CNC milling centers and two CNC machining (turning-milling) centers.

Coloral SA is a leading manufacturer of CNC lathes and CNC milling centers.

Mainly active in the watchmaking sector, Coloral SA is proud to be able to offer its services also to the medical, machine tool, mechanical and electronics industries.
