Title:
METHOD FOR MANUFACTURING INJECTION-MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2023/054097
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for manufacturing an injection-molded body of a resin composition containing a P3HA-based resin, the method enabling stable continuous production to be possible without generating burrs. The purpose is achieved by a method for manufacturing an injection-molded body of a resin composition containing a P3HA-based resin by using a mold device, the method comprising a depressurizing step in which: the maximum width of a parting line in contact with the cavity in a mold in the mold device when the mold is closed is at most 50 μm; and the gauge pressure in the cavity of the mold before the mold is filled with the resin composition through injection is reduced to at most -0.02 MPa.
