Patent number: 8062025Abstract: An injection molding apparatus includes a manifold defining a manifold channel for receiving pressurized molding material from an upstream source and a nozzle defining a nozzle channel in communication with the manifold channel to define a flow channel. The nozzle is associated with a mold gate of a mold cavity and delivers molding material to the mold gate. A vane, such as that of an impeller or screw, is rotatably disposed in the flow channel upstream of a mold gate. A motor is coupled to the vane and rotates the vane in either direction. Rotation of the impeller or screw can be automatically adjusted by a controller and a sensor that measures pressure, temperature, or other property of the molding material.Type: GrantFiled: December 18, 2009Date of Patent: November 22, 2011Assignee: Mold-Masters (2007) LimitedInventors: Peter Klobucar, Bruce Catoen, Rhonda Goslinski

Patent number: 7988445Abstract: An injection molding apparatus includes a plurality of valve-gated nozzles, each nozzle having a respective valve pin that is actuated by an actuator. A nozzle tip component for taking one of the valve-gated nozzles of the injection molding apparatus out-of service, wherein the nozzle tip component has a surface that grips the respective valve pin to lock the valve pin in an out-of-service position thereby preventing flow of molding material into an associated mold cavity and causing disengagement of the valve pin from the actuator.Type: GrantFiled: September 8, 2009Date of Patent: August 2, 2011Assignee: Mold-Masters (2077) LimitedInventors: Payman Tabassi, Denis Babin, Rhonda Goslinski, Scott Gammon

Patent number: 7614872Abstract: An injection molding apparatus having a manifold and several manifold melt channels communicating with several hot runner nozzles includes a melt redistribution element. The melt redistribution element is placed at specific locations along the melt channels to balance the uneven shear stress profile accumulated during the flow of a melt along the manifold channels. The melt redistribution element has an unobstructed central melt bore having at its inlet a narrowing tapered channel portion. The melt redistribution element also includes a helical melt pathway portion that surrounds the central melt bore. The incoming melt is first subjected to a pressure increase by the tapered portion that causes the melt to flow at a higher velocity through the central melt bore. The outer portion of the melt is forced to flow along the helical path and thus it changes direction multiple times and partially mixes with the melt flowing through the central melt bore.Type: GrantFiled: October 4, 2005Date of Patent: November 10, 2009Assignee: Mold-Masters (2007) LimitedInventors: Gheorghe Olaru, Rhonda Goslinski

Patent number: 7134868Abstract: An injection molding nozzle with a tip portion in the gate area of the mold that has a wear-resistant diamond-type coating. The surface of the tip melt channel that delivers melt to the gate area may also comprise a diamond-type coating. Nozzle seal surfaces in the gate area may also comprise a diamond-type coating. The enhanced harness, smoothness and thermal conductivity of these coated surfaces results in higher quality molded parts, and easier to clean molding equipment that has a longer service life.Type: GrantFiled: November 26, 2003Date of Patent: November 14, 2006Assignee: Mold-Masters LimitedInventors: Denis Babin, Hans Guenther, Rhonda Goslinski
