摘要： A method for producing a foamed particle molded article provided with a skin, includes: forming a hollow molded article; filling a hollow part of the hollow molded article with polypropylene-based resin foamed particles; and heating and fusing the particles to each other. A melt elongation at 190° C. of the polypropylene-based resin forming the hollow molded article is 100 m/min or more. A half-crystallization time at 100° C. of the polypropylene-based resin is between 25 to 80 seconds. In heat flux differential scanning calorimetry, a melting peak temperature of the polypropylene-based resin is between 130 to 155° C., a partial heat of fusion at 140° C. or more of the polypropylene-based resin is between 20 to 50 J/g, and a ratio of the partial heat of fusion of the polypropylene-based resin to the total (partial heat of fusion/total heat of fusion) is between 0.2 to 0.8.

摘要： A method for producing a skin-covered foamed molded article including blow-molding a parison in a mold cavity to form a skin consisting of a hollow molded body, in which the parison is in a softened state by extruding a molten thermoplastic resin, filling expanded beads in the hollow molded body, and heating and fusion bonding the beads by supplying steam via a steam supply pipe inserted into the hollow molded body. The parison is in contact with a protruding portion, formed by protrusion from an inner surface of the mold cavity to an inside of the cavity, forming a recessed portion having a shape corresponding to the protruding portion in the inward direction of the hollow molded body. A steam hole is formed in the recessed portion, a steam supply pipe is inserted into the body, and the expanded beads are heated and fusion bonded by supplying steam.
