Patent number: 6971144Abstract: A manufacturing method of a polyurethane foam injected with strand mats and a device for increasing the volume of the strand mats. The method comprises the steps of: increasing the volume of each of the strand mats to weaken the cohesion between glass fibers in each of the strand mats; continuously supplying and transferring the volume-increased strand mats; spraying a polyurethane foam solution on the continuously transferred strand mats; and foam molding the polyurethane foam solution in which the strand mats are immersed, into a polyurethane foam. Because the cohesion between the glass fibers in the strand mat is weakened and the volume of the strand mat is increased, the polyurethane foam solution uniformly permeates into the strand mats. As a result, the productivity of the polyurethane foam is improved and the variations in a variety of the mechanical properties are minimized.Type: GrantFiled: July 2, 2002Date of Patent: December 6, 2005Assignee: Han Kuk Fiber Glass Co., Ltd.Inventors: Jong Sik Kim, Young Soo Kwon, Jung Meung Roh

The surface of the mold has a grain pattern that is transferred to a skin. The skin is allowed to flash off or partially cure before being removed from the male mold. The skin is then turned inside out with the exterior surface being inverted to form a convex portion of the skin. The skin is placed into a female mold having a concave portion against which the convex portion of the skin is placed. Foam is injected into the inverted skin while in a female mold and is cured to form an interior trim part.Type: ApplicationFiled: March 24, 2003Publication date: September 30, 2004Applicant: Lear CorporationInventors: Joseph J.

Patent number: 6787078Abstract: A process for producing a multi-layered article having a soft, leather-like feel comprising first introducing into a suitable mold a first liquid formulation designed to produce the top elastomeric layer on the finished article. A release agent is then applied on the elastomeric layer in the area where it is desired not to have adherence of the elastomer to the foam. Before the elastomeric layer is completely cured, a second liquid foam producing formulation, designed to produce a soft foam, is poured into the open mold. The elastomeric layer of the resulting article is integrally attached to the foam in the areas not containing the release agent.Type: GrantFiled: June 14, 2002Date of Patent: September 7, 2004Assignee: Dow Global Technologies Inc.Inventors: Steven English, Katherine J.

Publication number: 20040169301Abstract: A molded resin laminate in which the dimensional accuracy and the strength are excellent at a bent portion and a method for producing the same are provided. One, in which an average diameter of small cells existing in a region on a side of a resin cover to be formed into a surface layer is smaller than an average diameter of large cells existing in a region on a side of a base resin component to be formed into a base layer, is used as a foamed resin component to be formed into an intermediate layer of the molded resin laminate. After the base resin component is molded with a molding machine, the base resin component is held on a male mold of a forming machine different from the molding machine described above. A sheet-shaped laminate, which is obtained by joining the foamed resin component and the resin cover, is arranged between the base resin component and a female mold. Subsequently, the forming machine is subjected to mold clamping.Type: ApplicationFiled: March 8, 2004Publication date: September 2, 2004Applicant: HONDA GIKEN KOGYO KABUSHIKI KAISHAInventors: Kenichi Chujo, Kazushiro Wakabayashi, Hiroe Hashimoto

Patent number: 6764621Abstract: A method and apparatus for making a composite article that includes a soft trim component employs a pair of mold halves, wherein a suitable skin material is sprayed onto a first mold cavity surface to obtain an in-mold coating, and a substrate is positioned between the mold halves such that a first area of one side of the substrate is located in opposition with the in-mold coating. A sprue defined in the second mold half, in opposition with the other side of the substrate, directs injected foam through an aperture in the substrate and into a gap defined between the one side of the substrate and the in-mold coating. A portion of the first mold half includes a layer of a sealing material that is harder than the substrate material to thereby eliminate the need to otherwise trim the overmolded soft trim component upon release from the mold.Type: GrantFiled: November 1, 2001Date of Patent: July 20, 2004Assignee: Lear CorporationInventor: Armin Schwaighofer
