Ultra Valve Gate Technology Ultra 350 nozzles for direct access gating of small parts. Valve gating advantages Customers choose Ultra valve gates for applications that require superior gate quality and wide processing windows. Valve gating offers several benefits to the injection molder including: • Superior gate quality • Elimination of drool and gate string • Improved physical properties with lower molded-in stress • Fast cycle times • Ability to balance family molds and control weld line location with sequential valve gating • Added process control with valve gating Continuous improvements and new technologies have established the Husky® hot runner product portfolio as one of the most advanced and reliable in the industry. The Ultra nozzle family provides an unmatched combination of reliability and performance featuring superior gate quality, fast cycle times, wide operating windows and easy start-up over a wide range of applications. As one of the largest manufacturers of hot runners and temperature controllers worldwide, we continue to invest in our global infrastructure to build strong relationships with customers. No company delivers more valve gated nozzles than Husky on an annual basis and our customers trust Husky to provide the most reliable systems available. Added control with valve gating Molders gain control over gate opening and closing using a valve gated hot runner. The gate is positively sealed with the use of a valve stem. The actively controlled valve stem moves forward and seals the gate opening. The valve stem remains in the closed position during mold open and part ejection, preventing drool and stringing. The molded part separates from the gate without breaking or shearing plastic, leaving a small witness ring. Unlike thermal gating, gate quality remains consistent over a wide range of process conditions. Physical properties of the molded part are also improved with the use of valve gates. Due to larger gate diameters, valve gates generate less shear compared to smaller thermal gates. The result is a part with less molded-in stress, reduced warpage and better physical properties.
