G&W AM – Gas Injectors

Gas injector / Injector service kit

Nitrogen is charged – controlled by the control module – through the mold lines into the injector. The velocity of flow makes the needle move forward. The freely movable needle extends the molding time and the cleaning cycle. Additional gas channels prevent the melt from forming a skin around the injector. Upon pressure relief the needle moves backwards and wipes off impurities.

  • self-cleaning function
  • fast replacement with open mold
  • high reproducibility
  • increased service life and improved cleaning characteristics through coating of the needle
