Abstract

PURPOSE: To manufacture the titled moldings which are excellent in dimension stability and have elastic force and righting moment on the surface portion by a method wherein synthetic resin is injected in a melting shape and applied on a bark forming surface in metal molds for molding a foaming body, and preparatory foaming grains are filled and foamed and molded.
CONSTITUTION: Thermoplastic resin 8, which is the 300% modulus of PE, PP, etc. and is 50kg f/cm2 or less, is injected in a melting shape and applied on a bark forming surface 2 with an uneven pattern of a female mold 1b of metal molds 1 for molding a foaming body so that the resin be made up in approximately uniform thickness, a male mold 1a to which a proper number of exhaust holes 5 are formed is covered, and the metal molds 1 are closed. The preparatory foaming grains 9 of PS are charged and filled into the metal molds 1, steam is sent in from the steam holes 4 of the male mold 1a to heat the grains, the grains 9 are foamed, the grains 9 are mutually bonded, foaming bodies 9' are molded while the resin 8 is attached in a melting shape, bonded and unified on the surfaces of the foaming bodies 9', the metal molds 1 are cooled, the male mold 1a and the female mold 1b are divided, and foaming PS moldings 3 integrally having a bark layer 8' are extracted.
