NEW TECHNOLOGY

● increase in the utilization rate of electricity due to a decrease in electricity consumption by
1.5 - 3 times;
● the possibility of high-quality processing of blind and through holes;
● simplicity and reliability of screen protection against nitriding of non-hardened surfaces;
● insignificant deformations of products during processing and changes in roughness parameters,
lower temperatures;
● obtaining a nitrided layer uniform in thickness on all surfaces of products;
● improvement of sanitary and hygienic conditions of production.
