ABSTRACT:
An injection molding apparatus is provided. The injection molding apparatus includes a manifold having at least one runner that receives melt from a melt source, a heat source for heating the melt, a nozzle in fluid communication with the manifold, and a mold component having a mold cavity for receiving melt from the nozzle. The nozzle includes a nozzle body having a melt passage therethrough, a nozzle tip having a tip melt passage therethrough, wherein the tip melt passage is in fluid communication with the melt passage of the nozzle body, and a tip surrounding piece that is removably coupled to the nozzle body. The tip surrounding piece retains the nozzle tip in position with respect to the nozzle body. The tip surrounding piece is preferably formed of a material that has a thermal conductivity that is equivalent to that of the nozzle tip.
