ABSTRACT:
An injection molding nozzle having a melt channel with a number of diagonal portions which branch to equally spaced outlets for multi-cavity molding. The nozzle has an integral electrical heating element with a forward portion which extends adjacent the forward face of the nozzle between the spaced outlets of the melt channel. The forward portion of the heating element is integrally brazed in channels in the forward face of the nozzle and has a number of radially extending arms. One of the arms extends outward midway between each two adjacent outlets. This provides additional heat to the melt near the outlets and ensures it is evenly balanced between the diagonal portions of the melt channel.
