Abstract
An injection molding nozzle for disposition in a mold. The nozzle is for injecting melt into a cavity of the mold, and includes a body having a through bore extending therethrough for receiving the melt. Attached to the body of the nozzle is a nozzle piece secured to the body that defines an outlet communicating between the body through bore and the cavity gate. A nozzle member surrounds the body at a position upstream of the nozzle piece and has an inner surface contacting the body, and an outer surface contacting the mold. The outer surface forms a seal against melt flow upstream from the nozzle member.
