For valve gate applications, UltraGuide technology pre-aligns the valve stem prior to entering the gate area achieving excellent gate quality.

• Reduced gate and stem wear—up to 5 million cycles with no visible wear
• Cylindrical shut-off for superior gate quality across a range of operating temperatures
• Thermally conductive tip component for easy start-up and wide processing window

UltraSeal technology guarantees leakproof operation for three years. UltraSeal prevents leakage at start-up, even if the hot runner is not in its correct operating temperature range.

• Nozzles are pre-loaded to the manifold to provide leakproof operation at cold condition
• Leakproof operation over a wide processing window (up to +-100C) for increased processing flexibility
• The UltraSeal spring provides component protection against overheating – the wide operating window prevents damage to nozzles and plates
• Spring forces are optimized to minimize plate bowing

The UltraFlow nozzle tip's patented technology provides melt mixing prior to the melt entering the cavity, leading to improved part tolerances and color changes up to 10 times faster than with traditional nozzle tips.
Benefits:

• Improved melt homogeneity for less molded-in stress and mechanically improved part properties
• Elimination of flow-lines in valve gate and hot tips
• Improved color consistency and melt distribution, even for metallic and pearlescent resins
• Color changes up to 10 times faster than a traditional hot tip

Ultra hot tip nozzles offer an optional wear resistant tip insert for improved longevity while processing abrasive materials.

The thermal design of Ultra nozzles and tips provide a wide operating window providing the molder maximum processing flexibility while molding quality parts .

• Wide temperature range without stringing or freeze-off
• Faster cycle times

Ultra Nozzles for thermal gates and valve gates allow for convenient maintenance and replacement of wear items.

• Tips, tip retainers, nozzle thermocouples and nozzle heaters are replaceable while the hot runner remains in the machine
• Valve Gate systems utilize a single O-Ring operating in a cooled backing plate for simplified maintenance
• Valve Gate O-Rings are serviceable without pulling the valve stems from the nozzles
