An injection nozzle for tools handling polymers incorporates an embedded electric heating element (2) that can be controlled separately and operates at high temperature, e.g. 800 [deg]C, to provide brief infra-red heating. The transparent nozzle body (1) is anisotropic and has a higher conductivity...
