A gun for discharging a thermoplastic material by passing the material around a torpedo heated by induction currents is constructed so that the torpedo is supported by and part of the outlet nozzle body and extends along approx. the last third of the melt chamber passing through the gun. Pref. the torpedo tapers towards the outlet and from a hemispherical nose. Used for continuous or intermittent discharge of a thermoplastic material, the hottest zone is near the outlet to prevent fusion of material too far upstream within the gun between periods of use. |
