Publication number: 20150231809Abstract: An injection molding system is disclosed that utilizes a melt channel wherein at least a portion of the melt channel has a noncircular cross-section for balancing shear in a melt stream of moldable material that flows therethrough. The noncircular cross-section of the melt channel portion may be, for e.g., capsule-shaped, extended egg-shaped, oval, teardrop-shaped, or peanut-shaped. A flow splitter is also disclosed that is positioned offset from a central axis of an upstream melt channel to protrude between inlets of respective downstream melt channels, where the upstream melt channel splits into the downstream melt channels, to thereby create a narrower inlet into one of the downstream melt channels and a wider inlet into the other of the downstream melt channels.Type: ApplicationFiled: May 1, 2015Publication date: August 20, 2015Inventors: Hitesh Kaushal, Harold Godwin

Patent number: 7918663Abstract: An injection molding apparatus includes an injection molding nozzle having a nozzle body defining a channel for flow of molding material and a nozzle tip coupled to the nozzle body. The nozzle tip is shaped to define a converging gap with a mold component into which the nozzle tip is inserted during use. A seal piece having a wedge or wedge-like portion is disposed between the nozzle tip and the mold component Pressure of molding material acting on a surface of the wedge portion wedges the wedge portion into the converging gap.Type: GrantFiled: March 5, 2009Date of Patent: April 5, 2011Assignee: Mold-Masters (2007) LimitedInventors: Hitesh Kaushal, Douglas Ursu

Patent number: 7874833Abstract: An upstream runner component defines an upstream channel for flow of molding material. A downstream runner component defines a downstream channel for flow of molding material. A wedge seal is disposed in a converging gap defined surface of the upstream runner component and the downstream runner component. The wedge seal defines a seal channel connecting the upstream channel to the downstream channel. Pressure of molding material acting on an inside surface of the wedge seal defining the seal channel pushes the wedge seal into sealing contact with the surfaces of the upstream runner component and the downstream runner component defining the converging gap.Type: GrantFiled: May 3, 2009Date of Patent: January 25, 2011Assignee: Mold-Masters (2007) LimitedInventor: Hitesh Kaushal

Patent number: 7850442Abstract: An injection molding apparatus includes a manifold having a manifold melt channel for receiving a melt stream of moldable material under pressure and at least one nozzle having a nozzle melt channel in fluid communication with the manifold melt channel. The nozzle has an opening that intersects with the nozzle melt channel, the opening having a central axis that is at an angle with respect to a central axis of the nozzle. A nozzle tip is coupled to the nozzle at one end of the opening. A valve pin bushing is coupled to the nozzle at an end of the opening opposite the nozzle tip. A valve pin extends through the opening. A primary actuator is connected to the valve pin. A nozzle locator piece is connected to the nozzle for mating with a side plate to locate the nozzle with respect to the mold gate.Type: GrantFiled: June 20, 2008Date of Patent: December 14, 2010Assignee: Mold-Masters (2007) LimitedInventors: Fabrice Fairy, Hitesh Kaushal, Douglas Ursu
