Abstract

A method of molding a composite foam molding element comprising attaching a top side member to a first die side of a cavity between a pair of dies and a back side member to a second die side of the cavity; supplying raw material beads made of a foam resin to an intervening charging space; discharging air from a plurality of work piece nozzles located at the side of the die wherein the back side member is located; starting air discharging from a work piece nozzle located at a most distant position from a charger for supplying raw material beads when the raw material beads are supplied; charging raw material beads during the starting air discharging step and sequentially discharging air from work piece nozzles located successively closer to a work piece nozzle located at the most proximal position from the charger as raw material beads are charged; and heating charged raw material beads to cause foaming and fusion to integrate a top side member and a back side member with each other via a foam member.
