Publication number: 20080299246Abstract: A mold assembly having a first mold portion with a first cavity having a retention groove. A second mold portion associated with the first mold portion and configured to come together therewith. The second mold portion has a second cavity. The second cavity and the first cavity form a first substrate compartment. A third mold portion is associated with the first mold portion and configured to come together therewith. The third mold portion has a third cavity having a shut-off member. The third cavity and the first cavity form a first over-mold compartment when the first and third mold portions come together. The shut-off member projects from the third cavity surface to impinge on a surface of a component formed by the first substrate compartment. The first retention groove mirrors the shut-off member and is aligned therewith when the first and third cavities form the first over-mold compartment.Type: ApplicationFiled: May 30, 2007Publication date: December 4, 2008Applicant: International Automotive Components Group North America, Inc.Inventors: Roger Catron, Bernard Chan, David Turczynski, Dennis Bunker

Patent number: 7143498Abstract: The present invention relates to a two-shot, non-shut-off method of manufacturing a 100% grained trim component for a vehicle. The method includes actuating a tool insert between a mold cavity and a secondary void to form a molded trim component having a groove. A first shot of material is injected to form a first trim element having a grained class-A side. During the first shot, flash enters the secondary void to provide a non-shut-off condition. The tool insert is retracted to define a ditch in the first trim element. A second shot of material is injected to form a second trim element having a grained class-A side, during which time a portion of the second shot enters the ditch to provide a non-shut-off condition. The trim elements are then bonded where a portion the second trim element bonded to the first trim element within the groove.Type: GrantFiled: February 24, 2004Date of Patent: December 5, 2006Assignee: Lear CorporationInventors: Michael P. Schoemann, John Youngs, Thomas W. Spanos, William J. Noble, David Turczynski

Publication number: 20060119136Abstract: A method and apparatus for manufacturing a vehicular panel (10) with a region of weakness that permits the panel to deform at predefined locations in a prescribed manner in response to an incident force (F). The panel (10) has a substrate with an exposed surface (“A”) side (14), a hidden surface (“B”) side (12), and a core section (16) extending therebetween. The method comprises the steps of (I) molding the part; (II) optionally, curing the part; (III) placing the part in a holding fixture; (IV) securing the “A” surface opposite an area of the “B” surface in which a scoring step is to be performed; (V) applying a scoring tool to the “B” surface to define a scored part with one or more notches (18) that extend inwardly from the “B” surface into the core section so that the one or more notches are invisible when viewed from the “A” side of the part; and (VI) retracting the tool and removing the scored part from the fixture.Type: ApplicationFiled: December 3, 2004Publication date: June 8, 2006Applicant: LEAR CORPORATIONInventors: Richard Trombley, Kenneth Hodges, David Turczynski, Thomas Spanos, David Dooley

Patent number: 6939504Abstract: A method and system for producing hollow rib structures for trim components and panels using gas assisted injection molding. Movable insert members are provided in the mold cavity, particularly at the ends of the structural rib members. After the plastic material is injected into the mold cavity, the plastic is packed in the mold, and the insert members are locked in position. Selectively activatable locking mechanisms are used to lock up the insert members. Thereafter, gas or another fluid is introduced into the rib members in order to provide hollow channels therein. Movement of the insert members provides a recess or groove for placement of the displaced resin from the rib members. The displaced resin material completes the formation of the molded plastic article.Type: GrantFiled: June 20, 2003Date of Patent: September 6, 2005Assignee: Lear CorporationInventors: Gregory A. Homann, James Hendry, David Turczynski

Patent number: 6890478Abstract: A method and system for producing thin walled plastic products with hollow rib members using gas-assisted plastic injection molding. The mold is allowed to open a predetermined distance as the gas is injected into the plastic material in the mold cavity. A plurality of post members, such as ejector pins, are located on a biased ejector frame and maintain their positions relative to the mold cavity in order to form solid portions or areas in the molded part.Type: GrantFiled: June 20, 2003Date of Patent: May 10, 2005Assignee: Lear CorporationInventors: James Hendry, Gregory A. Homann, David Turczynski

Patent number: 6890477Abstract: A method and system for producing hollow rib structures for trim components and panels using gas assisted injection molding. Spring biased movable insert members are provided in the mold cavity, particularly at the ends of the structural rib members. After the plastic material is injected into the mold cavity, gas is introduced into the rib members in order to provide hollow channels therein. The displaced resin material forces the insert members to the full cavity positions and completes the formation of the molded plastic article.Type: GrantFiled: March 25, 2003Date of Patent: May 10, 2005Assignee: Lear CorporationInventors: Gregory A.

Patent number: 6730262Abstract: A method and system for producing hollow rib structures for trim components and panels using gas assisted injection molding. Rotatable insert members with recesses therein are provided in the mold cavity, particularly at the ends of the structural rib members. Once the plastic material has been injected into the mold cavity, the insert members are rotated, exposing said recesses to the mold cavity. Then, gas is introduced into the rib members displacing a portion of the molten plastic material into the recesses forming hollow channels or openings in the plastic material. The displaced resin material completes the formation of the molded plastic article.Type: GrantFiled: June 20, 2003Date of Patent: May 4, 2004Assignee: Lear CorporationInventors: James Hendry, Gregory A.
