Method for manufacturing plastic construction part, involves injecting plastic component into cavity of injection molding tool and injecting another plastic component into cavity

摘要

The method involves injecting plastic component (4) into a cavity (6) of an injection molding tool (8) and injecting another plastic component into the cavity, where the latter plastic component is provided with a blowing agent. The method involves magnifying cavity before solidifying the latter plastic component, where an internal tool pressure is lowered and the latter plastic component expands by the blowing agent driven into the supplementary cavity. Independent claims are also included for the following: (1) a plastic construction part for use in hybrid construction; and (2) an injection molding tool.
