Abstract

PURPOSE:To prevent the generation of both internal and external strains due to integral molding by first extruding the reinforcement in the inside and then, after cooling, continuously introducing the resin into an extruder for external wall molding while forming the periphery with another resin. CONSTITUTION:Molten resin is supplied from a first extruder 5 into a core-forming die 6 to form the core 2 alone and then it is passed through a first sizing die 7 into a first cooling tank to effect quick cooling and hardening. Then the resin is introduced into an external wall forming die 11 where the resin is melt-sticked to the core 2 continuously along each line directing to the longitudinal direction while forming the external wall on the core 2. During this operation, the molten resin of the external wall 1 is bonded to the corresponding ends of the respective supporting walls 2a of the cooled core. The bonding effect is improved by the cooling shrinkage of the resin. Thus, since the wall faces of the core are formed by the core alone, it is solidified without deformation, so that it can withstand the pressure at the time of bonding to the external wall 1 and also deformation of the product is prevented.
