SUPERFINISHING WITH PHYSICAL VAPOUR DEPOSITION
Vacuum metallisation (PVD) is an extremely high-technology treatment habitually employed for the tools used in high-velocity steel machining. It is applied to products that have already been chromed, in order to obtain maximum resistance to wear and tear. In fact, PVD increases the surface hardness to three times that of chromium plating. Since 2004 HeleH has been using this technology, which has the additional benefit of offering metallic colours that cannot be produced with traditional galvanisation. PVD coating has exceptional performance in stability and longevity of the colour, making the products last and last. If used in accordance with the instructions and maintenance guidelines, HeleH Superfinishing in Gold, Nickel and Stainless Steel have a 30-year guarantee. Superfinishing in Anthracite, Copper and Bronze have a 10-year guarantee.
