Patent number: 8287789Abstract: A process for the production of a molded article is disclosed. The process comprise a) placing a plastic film abutting the inside wall of a first half of a mold, said mold including a first and second halves, b) combining said second half with said first half in a manner creating a mold cavity, c) injecting resin into said cavity to produce an article to which surface adherently bonded is said plastic film, d) separating one of the halves from the other half, said article remaining with said other half, e) combining a supplemental half with said other half in a manner forming a gap between the inner wall of said supplemental half and the surface of said molded article, f) injecting lacquer into said gap, g) curing the lacquer to produce a lacquered molded article, and h) cooling and removing the lacquered molded article from the mold. The inventive process is particularly suitable for making vehicular mirrors.Type: GrantFiled: December 21, 2005Date of Patent: October 16, 2012Assignee: Bayer MaterialScience AGInventors: Olaf Zöllner, Thorsten Just, Winfried Kohl

Publication number: 20080182046Abstract: A method of forming a multi-component molded article is described. The method includes first introducing a first plastic film and a second plastic film separately into a first cavity of an injection mold, the first and said second plastic films each being positioned within the first cavity so as to form a void there-between. Next, a first thermoplastic material is injected into the void, thereby forming a first molding. The first molding is then released from the mold, and the first molding and at least one second molding are together introduced into a second cavity of the mold. Finally, a second thermoplastic material is injected into the second cavity of the mold, thereby combining the first molding and second molding together thus forming a multi-component molded article.Type: ApplicationFiled: July 10, 2006Publication date: July 31, 2008Inventors: Roland Brambrink, Hans-Jorg Dahmen, Winfried Kohl, Olaf Zollner
