  • Method and device for producing a pipe member
    Patent number: 9321195
    Abstract: An object of the present invention is to provide a method for producing a pipe, which is capable of reducing the amount of thermoplastic material, without complicating an device for producing a pipe. The present invention provides a method for producing a pipe, comprising a thermoplastic material filling process for filling a die with a thermoplastic material, and a thermoplastic material discharging process for pushing out an unsolidified part of the thermoplastic material in the molding die using pressurized fluid, wherein the thermoplastic material is mixed with a foaming agent, the method further comprises a process for foaming the thermoplastic material filling the molding die, and the thermoplastic material discharging process is a process for pushing out a inner part of the thermoplastic material foamed in the molding die, by using the pressurized fluid prior to solidification of the inner part.
