The main potential for coating with the SELGA-COAT® process is in the automotive industry and in mechanical engineering because, on the one hand, components are manufactured in large numbers and, on the other hand, the requirements for the coatings are very demanding.
SELGA-COAT® (selective hard anodising) has already proven itself excellently in the partial coating of vehicle parts, amongst other things, with brake system components, clutch components, engine pistons (diesel, petrol), pump housings (power steering), wheel hubs and bearings, valves (eg. injection pumps), valve piston (automatic transmission), intermediate plates (automatic transmission).
Rotationally symmetrical, preferably elongated components such as axes, spindles, shafts or tubes are suitable for hard chrome plating using the SELGA-COAT® CHROM process. Of course, any other component made from unalloyed or hardened steel can be hard chromium plated, if selective coating makes sense.
SELGA-COAT® GOLD coatings are primarily intended for electrical contact components. Very high demands are placed on the reliability of the connections of contact points in electronic devices, which can usually only be achieved with a gold coating. A precise partial coating also helps to minimise gold consumption and thus reduce costs.
AHC also specialises in designing SELGA-COAT® systems for installation in existing production lines of their customers.
