Heat treatment of metals in our furnaces and at the customer's site.

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

We are a heat treatment company and use our extensive experience in the industry from the past years. Quenching in conjunction with tempering produces the final properties of the tool, making this process the most important operation in production and recovering the value of the material used.

Offering services in heat and chemical treatment of metals.

We are in the business of metallurgical technology, material analysis, mechanical testing and thermophysical measurements, computer modeling. Due to the support of scientific capabilities and international experience of our staff, we handle orders at the highest professional level and in the shortest possible time.
