PROBLEM TO BE SOLVED: To provide a multilayer molding die for molding a multilayer tube having sure interlaminar strength, and to provide a molding method for multilayer molding, and the multilayer tube. ! SOLUTION: A multilayer tube 100 is formed by laminating a first layer 210 and a second layer 220. When laminating the second layer 220 on the first layer 210, gas between the layers can be removed properly from a degassing part 610. As a result, the adhesion degree between the layers can be heightened, and generation of a void can be prevented. ! COPYRIGHT: (C)2015,JPO&INPIT |
