Abstract: An injection molding system with an electric heater has a reusable high temperature electrical connection assembly that provides a very secure small diameter high current inline coupling. The system is comprised of a mold, a heater, connecting wire to a power source and a connector assembly. The heaters and the mold are conventional and well known in the art. The connector assembly, in a preferred embodiment, has a male portion and a female portion. Each is permanently connectable to two wire ends to be removably connected. The male connector portion has a metallic tubular portion with a first end open for insertion and attachment by crimping or brazing of one wire end, and a second end having exterior threads for joining to the female portion. The second end also has a conductive pin integral with the metallic tubing and extending axially outward therefrom.

Abstract: A low profile heater for plastic injection molding equipment nozzles utilizes forces provided to the axially ends of a tube portion to radially compress the tube portion onto a coiled heater element thereby compressing the heater element radially inward for optimal heat conduction between said heater element and the nozzle onto which the heater is attached. Further embodiments uses a base sleeve onto which the coiled heater element is placed to engage the nozzle. The base sleeve may utilize a tapered threaded portion with slits in the sleeve to allow tightening of a ring portion to radially compress the sleeve base onto the nozzle.
