Abstract
A molded foam article with an integral skin is produced by blow-molding a parison in a cavity of a metal mold to form a hollow member, filling the hollow member with pre-expanded thermoplastic resin besides before cooling and solidification of the hollow member, and heating the pre-expanded beads to cause the beads to expand further and fuse together. A filler for the pre-expanded thermoplastic resin beads is provided with a cutter for making a hole in the hollow member before introducing the resin beads into the hollow member.
