Abstract
In charging a fluid molding material in an elastic molding die composed of a die body having an opening and a die support portion extending from the opening to the outside by pouring the molding material from the opening into time die body, the molding material in an amount of 1/5 to 3/5 of a volume of the die body is first charged, a molding material-charged portion of the die body is then crumpled or pinched, and then the entire die body is filled up with the molding material. The crumpling or pinching operation is achieved by such means as a blade shutter, pressing plates, air bags, or passing between two plates or conveyor belts, thereby charging the fluid molding material in the die body of the elastic-molding die without occurrence of air voids.
