20090194910 | Two Stage Spring Pack Device for Hot Runner Sealing - A two stage spring pack device comprising a nozzle or back up insulator, surrounded by a first stage spring for applying an initial force, and a plurality of Belleville springs to exert a secondary force against a thermally expanding hot runner manifold in an injection molding system, precludes resin leakage between a manifold and nozzle or between mating manifolds in a cross manifold system. The first stage spring imparts a relatively low initial force against the hot runner components while the system heats up from ambient temperature to prevent plate bowing and component hobbing, until it is fully compressed, at which point a subsequently larger sealing force is exerted by the constant force Belleville springs to prevent leakage between the mating components at operating temperature and injection pressure. | 08-06-2009 |
20110027410 | Back-Up Device for Use in a Melt Distribution Apparatus of an Injection Molding System - Disclosed, amongst other things, is a back-up device that is configured to provide a structural support, in use, between a manifold and a housing member within a melt distribution apparatus of an injection molding system. The back-up device is associated, in use, with a valve-gate apparatus within a nozzle drop. The back-up device includes a cold-side member formed from a first material and a hot-side member formed from a second material. The first material is more thermally conductive than the second material. The cold-side member is configured to be thermally connectable, in use, with the housing member and the hot-side member. The hot-side member is configured to be thermally connectable, in use, with the manifold and the cold-side member. The hot-side member is also configured to prevent the cold-side member from directly contacting the manifold. | 02-03-2011 |

20120156323 | Hot-Runner System Including Melt-Flow Control Structure Integrally Formed with the Manifold Body - A hot-runner system is provided with a manifold body including a manifold melt channel, and a melt-flow control structure communicating with the manifold melt channel. The melt-flow control structure is integrally formed with the manifold body. | 06-21-2012 |
20120156324 | Mold-Tool System having Melt Splitting Device Including Uninterrupted Melt Channels Extending from Inlet and Outlets - A mold-tool system is provided which includes a melt distribution device and a melt splitting device configured to interact with the melt distribution device. The melt splitting device includes a single inlet and multiple outlets spaced from the single inlet. The outlets are configured for fluid communication with the melt distribution device. The melt splitting device further includes a plurality of uninterrupted melt channels, where each melt channel extends from the inlet to an associated one of the outlets. | 06-21-2012 |
20130064922 | Injection Molding System having Dynamic Mixer - A dynamic mixer and associated injection molding system for mixing a melt flow. The injection molding system includes: a hot runner assembly having a plurality of splits; an injection unit that delivers a melt flow to the plurality of splits in the hot runner assembly via a melt channel; and a dynamic mixer incorporated into the melt channel upstream from the plurality of splits, wherein the dynamic mixer includes a rotor assembly configured to be rotationally driven by the melt flow, and wherein the rotor assembly is further configured to mix the melt flow passing through the melt channel. | 03-14-2013 |
