RUBISAN and SANJO HEAT TREATMENT are our plants for heat treatments. There, we offer the continuous or transfer treatment required for the production of the parts. This gives us the ability to provide the customer with a comprehensive service, which is one of our differential distinguishing elements. We provide greater flexibility and optimise delivery times. Currently, our production capacity stands at 9,000 tones per year, of which 20% is acquired by other companies outside the group.
