Abstract

PURPOSE: To make the demolding easy as well as to increase smoothness of an inner wall surface of the molded product by forming the inner mold portion for molding an undercut portion of the molded product by a low mp substance.
CONSTITUTION: For example, te inner mold 1 for moldig an FRP pipe joint 10 is consisted of an outer shell mold 2 and a core mold 3 inserted into the outer shell mold 2 in a freely slidable manner. The FRP pipe 10 is molded on an outer periphery of the inner mold by using a resin and a reinforcing material or the like and cured thereon and, thereafter, if the core mold is withdrawn and, moreover, the outer shell mold 2 comprising a paraffin wax or a low mp alloy is melted and removed by heating, the FRP pipe having the inner wall surface with excellent smoothness can be obtained easily.
