A method for degating an injection molded article comprising the steps of filling a mold cavity with a molten resin and cooling the mold to effect gate seal. A gate cut shaft member is oscillated after gate seal is completed to soften the hardened resin in the gate. The gate cut shaft member is then displaced with respect to the mold cavity when the resin is softened to effect degating. A second method comprises the steps of cutting the gate in the molded article by sliding the gate cut shaft member during the dwell process with respect to the mold cavity after filling the mold with molten resin and before gate seal is effected. While said gate cut shaft member is subject to minute oscillation or a slow reciprocating motion, the shaft surface is abutted against the degated surface to obtain a good cut surface on the molded article.
