Electric heater for the molds of plastic substances consisting essentially of a metallic tube bent by joining its ends in loop ge. So that several parallel branches remain and join the ends in a piece that supports the terminal terminals of the electrical resistances that go far inside the tube occupying its central part and isolated from its walls because they are surrounded by a mass of powdered isolating material.
