Abstract

Hot runner for injection moulding systems of plastic materials, characterized in that it is made up of two sections (A, B) for creating the channels (C) for flow of the fluid in an optimal way, said sections being subsequently brazed in a hydrogen furnace, and finally coated, by means of thermal spray (APS), with resistive elements (E) for heating the plastic material that is to be injected to the temperature of fluidity.
