This invention relates to an injection molding process for synthetic resin and its apparatus which enable to produce highly precise molded articles and shorten the molding time. More particularly, by actuating a forcible cooling means disposed in a runner and extended into a gate, the fused resin in the gate is cooled and solidified locally, thereby the gate is closed. On the other hand, by stopping the forcible cooling means, the solidified resin in the gate is heated and fused by a heater mounted either inwardly of a runner or outwardly thereof.
