Beschreibung
Zusammenfassung:	A sleeve heater for supplying heat to a melt delivery component of a hot runner system. The sleeve heater includes a tube-shaped body having an outer surface and an inner surface. The inner surface of the tube-shaped body defines an opening in which a melt delivery component is received. A heater wraps at least partially around the tube-shaped body and extends along a length of the tube-shaped body. A thermocouple groove is formed in the outer surface of the tube-shaped body. The thermocouple groove includes a lateral bend; and a bore that extends from the lateral bend into a thickness of the tube-shaped body. Together the bore and the latera bend maintain the position of a sensing end of a thermocouple installed therein relative to the tube-shaped body.
