  • NOZZLE-TIP APPARATUS INCLUDING A NOZZLE-TIP BODY HAVING PRESSURE-RELIEF FEATURE
    Publication number: 20130287889
    Abstract: A nozzle-tip apparatus (100), comprising: a nozzle-tip body (102) configured to connect with a molding-nozzle assembly (200). The nozzle-tip body (102) has a front end (104) defining an exit orifice (106). The exit orifice (106) is configured to slidably receive a valve stem (202) of the molding-nozzle assembly (200). The nozzle-tip body (102) has a pressure-relief feature (108).

  • Mold-Tool System Including Air Cavity Circuit, and Means for Forcing Relatively Cooler Air Stream to Air Cavity Circuit
    Publication number: 20130177666
    Abstract: A mold-tool system (100), comprising: (i) a hot runner manifold assembly (102), (ii) a plate assembly (104) defining an air-cavity circuit (106), the plate assembly (104) being configured to support and surround, at least in part, the hot runner manifold assembly (102), and the air-cavity circuit (106) surrounding, at least in part, the hot runner manifold assembly (102); and (iii) means for forcing, in use, a relatively cooler air stream to the air-cavity circuit (106), wherein that the air-cavity circuit (106) is configured to: (i) increase, in use, thermal losses of the hot runner manifold assembly (102), and (ii) reduce time to cool down the hot runner manifold assembly (102) relative to heat lost as a result of natural convection associated with the hot runner manifold assembly (102).

  • METHOD AND APPARATUS FOR COUPLING MELT CONDUITS IN A MOLDING SYSTEM AND/OR A RUNNER SYSTEM
    Publication number: 20080199554
    Abstract: Disclosed is a hot runner for conveying a metallic-molding material. The hot runner includes: (i) a first conduit, and (ii) a second conduit. The first conduit is configured to receive the metallic-molding material. The second conduit is configured to receive the metallic-molding material from the first conduit. The first conduit is thermally expandable relative to the second conduit sufficiently enough so that an interference seal forms between the first conduit and the second conduit. The interference seal substantially prevents a leakage of the metallic-molding material from the first conduit and the second conduit.
