About us

Our business line Electroplating develops products for electroplating (precious metal) for the highest demands for both technical and decorative applications.

Our decorative processes fulfil the needs and wishes for a (precious) metal surface that is not only visually high-quality. Decide on the colour, gloss and reflection of your product, but also on its haptics and abrasion resistance - and thus on its value and elegance in the view of the end user. Of course, we always keep an eye on current trends and price developments for individual raw materials. In this way, we can offer you modern processes that are as cost-efficient as possible in the following segments, for example.

Give your product the decisive advantage - a perfect surface through electroplating.

Jewellery Tools & Equipment

Are you looking for electrolytes for the surfaces of costume and luxury jewellery? Brilliant sparkling finishing layers are popular worldwide – we serve you with a carefully arranged variety of electrolytes for noble surfaces, by the way, also for timepieces.

Alternatives to rhodium and palladium layers

The prices for rhodium and palladium have exploded over the last few years along with production costs. In order to be able to continue to serve the market, a rethink in surface plating is required. Alloys represent a way out for both decorative and technical applications, with almost no compromise in quality and appearance. On the contrary - through innovative processes, we have succeeded in improving properties such as abrasion resistance or adapting colour composition as required.

AURUNA® 215 Pale Gold Iron Indium Electrolyte

AURUNA® 215 Pale is a colour gold alloy electrolyte for decorative applications, preferably for parts coming into contact with the skin such as jewelry and watches. The essential advantage of the coatings is their freedom from nickel and cobalt, excluding skin allergies caused by these metals.
The process has already been proven for many years. By changing the parameters, we can now also achieve a pale yellow color (1N). It is easy to operate and suitable for rack and barrel.

AURUNA® 502 Rose Gold Electrolyte

AURUNA® 502 is a neutral, cadmium-free gold copper electrolyte working without free cyanide. The red surfaces are bright, very hard and abrasion-resistant. As gold-saving, low-carat layers, the surface exhibits very good corrosion and tarnish resistance. The gold copper electrolyte can be used for rack and barrel plating, it can deposit layers of up to max. 10 μm in thickness.
