We offer custom induction hardening services. We do large and small batch orders. We are a supplier to engineering companies.

We deal with heat and chemical-thermal treatment of metals. We carry out hardening, annealing, refining, nitriding, carbonitriding, tenifer, oxidation, cementing, nitrocementing, blackening, blasting, plating, chemofinishing, ceramofinishing, straightening, freezing.

We perform artistic casting of non-ferrous metals, chiselling and patination, welding in protective argon atmosphere, blasting with compressed air.

We deal with heat and chemical-thermal processing of metals. We carry out hardening, annealing, refining, nitriding, carbonitriding, tenifer, oxidation, cementing, nitrocementing, blackening, blasting, plastering, chemofinishing, ceramofinishing, straightening and freezing.

The main heat treatment technology is nitriding in a gaseous atmosphere. As a complementary service to the nitriding process, we offer surface oxidation after nitriding. There is also the possibility of protecting parts of surfaces, threads, holes before nitriding, annealing, tempering and inter-operative stabilization to remove stresses.

We offer heat treating and metal finishing. We provide vacuum and protective atmosphere heat treatment, high frequency surface hardening, annealing without protective atmosphere, plating, blackening and more.

Focus on special and complex piece production to individual customer requirements. We perform vacuum and surface hardening, nitriding or metal refining. We also provide high frequency surface hardening, straightening, freezing, annealing, oxynitriding, cementation, vacuum tempering and more.

We provide heat treatment of metals, preheating and annealing of welded joints. We offer sales and rental of annealing sources. Manufacture, sale and rental of heating elements for electro resistance heating. We provide hardness measurement of steel materials. We provide realization of electro resistance heating of steel materials.

We are involved in heat treating metals, lining drying, electric heating and semi-automatic welding.

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.
