Abstract

A method of making molded foam articles and the articles produced. A molded foam article is produced by heating or preheating the mold to a temperature at or above the glass transition or melt temperature of the particles to be molded. Foamed particles are then introduced into the mold. The particle filled mold is then subjected to a vacuum to stabilize the molded article, without application of any additional heating or cooling. The molded article is then removed from the mold at a temperature at or below the glass transition temperature of the particles, and the cycle repeated to form multiple molded articles.
