Husky Injection Molding Systems, a leading industrial technology provider to the plastics processing community, has released the newest addition to the Ultra HelixValve Gate nozzle lineup, the 250 T2. The advanced design of Ultra Helix nozzles minimizes wear, providing industry-leading gate quality and longevity. The 250 T2 was specifically developed to extend the benefits of the Ultra Helix technology for small part weights with difficult to access gate locations.
With a 12mm nozzle bore, the 250 T2 allows for direct gating in locations not achievable with larger nozzles. The pitch spacing down to 15mm enables the highest cavitation density and smallest mould footprint. Its extended maintenance interval PX actuation is designed for applications with leakageprone resins such as TPE and PE. The addition of a stem seal paired with enhanced thermal management heater technology improves performance and optimises maintenance requirements. This results in lower risk and cost of ownership.
Three actuation options are available: the Individual Pneumatic option offers pitch spacing down to 25.4mm, providing ease of access for maintenance with the ability to individually access valve stems without removing the backing plate. Both the plate-actuated UltraSync-P or servo-driven UltraSync-E options can achieve 15mm pitch spacing.
Customers are using the 250 T2 to make high-quality precision parts from medical barrier closures and flow regulation valves to personal care products, food and beverage packaging and flip-top closures. The part weights being produced range from less than 0.1g to over 4g and are being made from resins that are prone to leakage, in both single injection and multi-material applications
The 250 T2 is already demonstrating its superior performance for small part weight with difficult-to-access gate location applications in both Individual Pneumatic and UltraSync®actuations. The extended maintenance interval for leakage prone resins is providing additional value for the customer.
