I will rework your material containing gold, silver and palladium, be it broken jewellery, dental gold, silver items, cutlery and other similar material into a bullion form of the pure metal. I can also process small quantities.
We offer hardening and ashing, refining, annealing, cementing, blackening, straightening and sandblasting. Heat treatment is carried out in chamber, wagon chamber and shaft furnaces.
Our company is engaged in metal surface treatment with a focus on the refinement of steel and cast iron by carbonitrooxidation technology using the arcor method, which our company uses as the only one in the country. The ARCOR technology (nitriding in a salt bath) offers a wide range of surface treatments for components.
We focus on heat and chemical heat treatment of metals. We offer hardening, annealing, tempering, cementing, nitriding and surface hardening. We process formed, cast, structural and tool steel, cast iron and non-ferrous metals in a wide range of processes.
