Unlike plastic injection, the mold cavities for injection molded foam are designed smaller than the final part size. The parts expand rather than shrink. The amount of expansion is dependent on the material softness you require. The material remains in the heated mold during the cross-linking or cooking process. The cooking time is dependent on the thickness of the part. The mold opens very quickly when the cooking is complete. The part expands and explosively self-ejects from the mold cavity.
