    • Husky introduces high pressure Ultra 500 valve gate hot runner nozzle

      For release 2007-10-24

      DÜSSELDORF, Germany – Husky Injection Molding Systems Ltd. today announced its new high pressure, high stem force Ultra 500 valve gate hot runner nozzle. This patent pending design is well suited for applications such as consumer electronics components and thinwall technical parts that require injection pressure of up to 3 000 bar (43 500 psi) in combination with tight pitch spacing.

      “Husky’s new high pressure Ultra 500 valve gate provides high injection pressure for tight access parts,” said Keith Carlton, Husky’s Vice President, Hot Runners and PET Molds. “We believe that this is the smallest nozzle on the market that features a bore diameter that is less than 24 mm and is able to withstand pressure up to 3 000 bar.”

      Designed to meet the needs of consumer electronics customers, Husky’s high pressure Ultra 500 valve gate meets the increasing injection pressure requirements for parts such as cell phone components. Until recently, these parts could not be directly gated and cold runners had to be used. This innovation greatly improves customer productivity by allowing direct gating for tight pitch parts, elimintating the need for cold runners. Hot runners provide faster cycles, ease of automation and require less resin than cold runners.

      The high pressure Ultra 500 valve gate is available for 2- to 8-drop hot runners. The staggered stem actuation allows for sufficient stem force to produce high-quality gates for technical resins, including glass-filled materials. The independent stem actuation allows for sequential valve gate control, even with a tight pitch. This important feature allows for cavity fill fine-tuning to achieve optimum part quality, an important feature for consumer electronics customers.
