Abstract

Methods of making molded polystyrene articles are described. The methods include introducing steam into a mold simultaneous to filling the mold with foam particles, and cooling the mold without the use of cooling water. The method can be performed faster and with a lower temperature differential than conventional molding processes, permitting faster turn-around to the production of subsequent molded articles. The molded articles produced by the method can have thicker side walls, improved foam particle fusion, and improved compression properties as compared to conventional EPS molding processes.
