Abstract

A tensile stress is applied to solidified resin. The tensile stress is so small that the solidified resin formed in the sprue by solidification of molding material does not break and is so large that the solidified resin formed in the sprue is separated from the inner surface of the sprue due to a reduction in the diameter of the cross sectional area thereof. For the application of such a tensile stress, the runner stripper plate holding the solidified resin is moved away from the nozzle and sprue bushing. This state is maintained for a predetermined time to separate the solidified resin from the inner surface of the sprue.
