The apparition of new materials such as rubber, carbon fiber and their combination with special polymers and plastics, and the subsequent industrial treatments, has caused a revolution in industry. Special curing treatment done in OLMAR autoclaves, makes possible the consolidation of these components, obtaining small pieces for the automobile industry, airplane parts for the aircraft industry, parts and components used in sports, large rubber rolls,... All these is possible, when air is heated in the interior either by resistances or steam with the help of an interchanger. In other cases the curing process is done by using direct steam on the product. OLMAR autoclaves are able to develop both processes.
