ABSTRACT:
A method for producing components for injection moulding comprising a body made of thermally conducting material with expansion coefficient matching that of the insulating layers and provided with a passage for the material to be injected. At least one strip of electrically conducting material with high change of resistance with temperature, forming a heating resistor or inductor is applied on a electrically insulating base layer previously directly applied on the body. At least one final insulating layer with low thermal emissivity is then applied to optimise electrical efficiency. The method utilises thermal spray techniques and can be applied also for production of other heating equipment.
