A new $350 shut-off tip from Molders Choice Inc. in Solon, Ohio, allows injection molders to transform any standard replaceable-tip nozzle into a shut-off nozzle at a fraction of the cost of a conventional shut-off nozzle.
The nozzle tip installs easily in place of a standard seven-eighths-inch, No. 14 tip. The spring-loaded valve opens when the tip is run forward against the sprue, and snaps shut when the carriage pulls back for sprue break.
