摘要:
An injection compression molding method is characterized in that a resin is injected from a resin gate provided near a recess portion of a mold corresponding to a thick rib portion, gas is injected from the thick rib portion before the mold is closed and compressed, and thereafter the resin is made to flow back from the resin gate to an injection nozzle while the mold is closed and compressed.
