An edge gated injection molding apparatus includes a manifold having a manifold channel for receiving a melt stream of moldable material under pressure. A nozzle is coupled to the manifold and a nozzle melt channel of the nozzle receives the melt stream from the manifold channel. A mold cavity communicates with the nozzle melt channel of the nozzle and receives melt through a mold gate. The mold gate is located at an edge of the mold cavity. A chamber receives melt from the nozzle channel and communicates with the mold cavity through the mold gate. A portion of the chamber is located forward of the mold gate. A valve pin is slidable through the nozzle channel from a first position in which the mold gate is open to a second position in which an outer side surface of the valve pin blocks the mold gate.
