Coating & Marking

Whether functional or decorative – we refine and mark each heat sink individually according to your requirements. The result: durable, protected, and clearly identifiable products for maximum transparency at every stage of production.

Surface finishing and marking – quality down to the last detail

Our surface and marking technologies ensure not only a perfect appearance but also functionality and traceability. High-quality coatings protect surfaces from corrosion and wear, while precise markings guarantee complete identification of every single heat sink.

Surface finishing

From decorative anodized finishes to functional coatings such as nickel or gold plating, we offer a wide range of finishing options for air and liquid coolers. In addition, protective passivations are available that meet specific corrosion and wear protection requirements, ensuring long-lasting durability.
