A line of spring-actuated needle shut-off nozzles has been redesigned for improved performance in high-temperature, high-pressure molding. The Spring High Performance (SHP) line from Herzog AG in Switzerland is offered here by Xaloy Inc., Pulaski, Va. The nozzles have a new modular design based on Herzog's HP needle shutoff. The SHP nozzle isolates the spring package from the melt stream so spring function can be checked externally. Reduced spring loading in the new version allows the system to be kept open with less force. The nozzle reportedly performs at up to 43,530 psi injection pressure and operating temperatures to 752 F. Nozzles come with a 0.5-mm orifi ce, 116-mm body length, and 24-mm tip length. They handle injection rates up to 1600 cc/sec. Tel: (540) 980-7560 . www.xaloy.com
