Improvement of conditions in foundry workplaces, using new ceramic mold materials for full mold casting
Abstract
Castable calcium silicate hydrate (CSH) mold materials were developed for the manufacture of lost (combustible) polystyrene molds. General introduction of full mold casting is in the interest of the humanization of conditions in foundry workplaces since it reduces the work involved in fettling and deburring the cast parts. The development was achieved by incorporating thermally conductive SiC components into the CSH materials. Parts of molds relevant to foundry technology were then made from polystyrene in thin walled SiC-filled molds. These results, achieved in the laboratory, can now be applied on an industrial scale in the production of molds.
