Abstract
A hot runner system, in particular a heatable injection nozzle for an injection molding machine or plastics injection mold, includes a central heating rod having opposite ends and defining a longitudinal axis, a sleeve assembly which surrounds the heating rod and is split radially to define first and second sleeves abutting one another, and current-conducting means for feeding an electric current to the sleeve assembly. The heating rod is electrically connected with each end of the sleeve assembly. One of the sleeves is formed at the interface to the other sleeve with a flange which extends substantially parallel to the longitudinal axis and forms at least one flow passageway for melt, whereby the flow passageway is bounded along its entire length by a wall surface made entirely of metal.
