MOLDING METHOD AND MOLDING SYSTEM FOR RESIN MOLDED MEMBER

Provided are a molding method and a molding system for improving a molding speed of a resin molded member. In the method, firstly a thermoplastic resin composite material is filled in a metal mold (i.e., at time TO), and subsequently a mold-clamping process gets started. As the mold-clamping process...

Zusammenfassung:	Provided are a molding method and a molding system for improving a molding speed of a resin molded member. In the method, firstly a thermoplastic resin composite material is filled in a metal mold (i.e., at time TO), and subsequently a mold-clamping process gets started. As the mold-clamping process progresses, a first decompression circuit (20a) starts to decompress an inside of a cavity when the cavity is closed by a sealing member (28) provided on the metal mold. Then, as the mold-clamping process further progresses, the thermoplastic resin composite material thus filled in the metal mold contacts an upper mold (12a) of the metal mold (i.e., at time T2). After that, a second decompression circuit (20b) starts to decompress the inside of the cavity, thereby to complete the mold-clamping process (i.e., at time T3).
