Patent number: 8709324Abstract: The present invention relates to a method for producing a flexible elastomeric composite polyurethane skin wherein a polyurethane reaction mixture is sprayed onto a mold surface and the polyurethane reaction mixture is allowed to cure to produce the skin layer. The polyurethane reaction mixture is composed of components comprising at least an isocyanate component, isocyanate-reactive components and a catalyst component and the isocyanate component is composed of at least one isocyanate having at least two NCO-groups which are not directly attached to an aromatic group. The catalyst component is substantially free of lead, which leads to a lower flexibility. In accordance with the invention, the flexibility of the polyurethane skin is increased by means of at least one flexibiliser which reduces the flexural modulus of the skin and which comprises at least one isocyanate-reactive group. The flexibiliser is preferably a monofunctional flexibiliser which comprises only one isocyanate-reactive group.Type: GrantFiled: May 7, 2012Date of Patent: April 29, 2014Assignee: Recticel Automobilsysteme GmbHInventors: Kristof Benoit, Peter DeWilde, Geert Van Houcke, Koen Vanlandschoot, Yvan Vanluchene, Hugo De Winter

Patent number: 8506866Abstract: The invention relates to a method for producing a multilayered part which comprises a moulded core (5) and a flexible polyurethane skin layer (4). The core itself comprises a moulded substrate layer (1) which is made of a substrate material, in particular a thermoplastic material, having a Shore A hardness higher than 60. The flexible polyurethane skin (4) is produced by a reaction overmoulding (ROM) process wherein a polyurethane reaction mixture is moulded in a closed mould (11, 12) over at least a first area of the core surface. The moulded core (5) comprises in addition to said substrate layer (1) a softer material which is moulded onto the substrate layer (1) and/or onto which the substrate layer (1) is moulded. This moulded softer material has a Shore A hardness lower than 60 and forms a softer layer (2) between the flexible polyurethane layer (4) and the substrate layer (1) and/or a seal (3) engaging the internal wall of the mould (11, 12) during the ROM process.Type: GrantFiled: May 15, 2007Date of Patent: August 13, 2013Assignee: Recticel Automobilsysteme GmbHInventors: Jürgen Deseure, Koen De Metsenaere, Gert Raeymackers, Hugo De Winter, Siegfried Moens, Dirk Meert

Patent number: 8088319Abstract: A method for producing a panel assembly is provided. The panel assembly includes a panel and a gasket adhered to the panel and extending along at least a portion of the periphery. A curable composition is applied either directly or indirectly onto the panel and onto a mold surface onto which the panel has been positioned. When being applied on the mold surface, the curable composition has a dynamic viscosity which is lower than the dynamic viscosity of extrusion materials. In this way, a better surface quality can be achieved without having to exert a high pressure onto the curable composition. In contrast to the known RIM processes, the curable composition is not injected in a closed mold but is applied onto an open mold surface by means of an applicator device moving along at least the portion of the periphery of the panel.Type: GrantFiled: March 17, 2005Date of Patent: January 3, 2012Assignee: BASF SEInventors: Hugo De Winter, Stijn Langie, Gert Raeymackers

Patent number: 7842207Abstract: The panel-like laminate comprises a flexible skin (1), a rigid substrate (2) and an intermediate layer (3). The flexible skin (1) comprises a main part (8) which forms the front side of the laminate and at least one flange (9) which extends from the main part (8) of the skin towards the substrate (2) to form at least a portion of the lateral side of the laminate. In order to avoid foam leakage when molding the intermediate layer (3) between the skin (1) and the substrate (2), the flange (9) is extended by a border part (10) which comprises a flexible lip (11). The flexible lip is pressed against the rigid substrate (2) so that the flexible lip (11) forms a seal between the skin and the substrate. To prevent deformation of the skin, the border part (10) of the skin further comprises at least one continuous or discontinuous ridge (12) which extends along the flange (9) of the skin (1) and which prevents a sliding of this border part when closing the mold.Type: GrantFiled: August 22, 2006Date of Patent: November 30, 2010Assignee: Recticel NVInventors: Nele Bosman, Kristiaan Bracke, Bart Broeckaert, Hugo De Winter, Jan Willems

Patent number: 7744799Abstract: The method according to the invention is a moulding method wherein a first layer (21), having a first colour, is produced against a first portion of a mould surface (10) and wherein, in a next step, a second layer (22), having a second colour, is produced against a second portion of the mould surface (10) and at least partially against the back of the first layer (21). The method is intended to obtain a qualitative transition between the colours of the two layers (21, 22) without having to hide the actual colour transition in a groove from view. This object is achieved by applying the material forming the first layer (21) in such a manner on the mould surface (10) that the edge (20) of the first layer (21), which will be situated on the mould surface underneath the second layer (22), is visually sharp and is produced without a mask.Type: GrantFiled: May 16, 2006Date of Patent: June 29, 2010Assignee: Recticel Automobilsysteme GmbHInventors: André Braeckman, Jan Willems, Yvan Vanluchene, Hugo De Winter

Patent number: 7431962Abstract: The invention relates to a method for manufacturing a multi-layered moulded synthetic part comprising a preformed elastomeric moulded skin (5), a moulded carrier (8) of a thermoplastic material and optionally an intermediate foam layer (6). In this method, the elastomeric skin (5) is moulded in a first step and the thermoplastic material for the carrier (8) is subsequently moulded in molten state to the back of said moulded skin (5). According to the invention, the moulded skin is made of a thermosetting synthetic material. Compared to a thermoplastic skin, such a thermosetting skin is less subjected to visible defects, in particular in case it has been provided with a superficial texture such as a leather grain, when the thermoplastic carrier is moulded thereto. Moulding of the thermoplastic carrier can be done by an injection moulding, an injection pressure moulding or a low pressure moulding technique.Type: GrantFiled: January 11, 2005Date of Patent: October 7, 2008Assignee: Recticel Automobilsysteme GmbHInventors: Hugo De Winter, Yvan Vanluchene, Hans Demandt, Ivo Deblier, Roger Hackwell
