Hot channel nozzle for plastic processing hot duct system, has nozzle body surrounding metal jacket so that metal jacket is material-conclusively connected with nozzle body, where wall of nozzle body is provided with coating

摘要

The nozzle has a nozzle body (11) made of metal in which a hot channel is trained. The nozzle body surrounds a metal jacket (13) so that the metal jacket is material-conclusively connected with the nozzle body. The metal jacket having a higher pressure strength than the nozzle body, where wall of the nozzle body is provided with a coating. Outside fastening parts are material-conclusively and integrally moulded to the metal jacket. An independent claim is also included for a method for manufacturing a hot channel nozzle.
