AEGIS' AGSA-1 Combination Resin Shutoff Valve & Gas Assist Nozzle Adapter.

Male end assembles directly to your standard resin injection nozzle turning it into a shutoff valve and gas injection nozzle.  7/8-14 threads male and female end. Uses your current nozzle tip on the female end of the adapter.  No actuation needed; positive cavity pressure following gas injection closes the shutoff devise and keeps resin and gas from returning to the nozzle and molding machine barrel during the gas-packing and cooling cycle.    For through-the-nozzle gas injection molding.

anti drool nozzle

The JDL Drool Eliminator - for Gas Assisted or Conventional Injection Molding - In stock!

The JDL Drool Eliminator! Save money, down time, messy cleanups! For use with Conventional Molding Processes, Structural foam or Gas Assist when injecting "in article." Click on the image for more information.

The Drool Eliminator uses a very heavy spring-loaded mechanism to prevent nozzle drool. To operate, use the sprue-break function on the molding machine to back off 1/2" from the sprue bushing and the nozzle is closed!

The Drool Eliminator comes with a special tool for opening the valve for purging the barrel. After purging, remove the special tool and you're ready for production.

In-process, the nozzle moves forward to the sprue bushing, opening the valve for resin injection. After resin injection and packing, "sprue break" approximately 1/2" and the nozzle is closed.

Dimensions: 6" x 2.50", with 1 3/4"-8 threads as standard. Available with non standard size molding machine end cap threads for any molding machine.

Effective nozzle drool prevention for any hydraulic, electric, or hybrid injection molding machine.
