Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a molding method for using a gas-assisting molding method. SOLUTION: The molding method includes the processes which comprise a process of making a member cavity by closing a die, a process of injecting a resin into the die, a process of making a hollow section in the member by charging a gas into a resin stream, a process of opening the die and a process of taking out a molded member by using a common die taking-out technology. The final process of the method includes the work of trimming the molding member and of exposing the through section of the parts. The parts are molded so as to have a seal structure due to its application to assembling the piping. COPYRIGHT: (C)2004,JPO
