Abstract
The invention relates to a method for producing a multilayered part which comprises a moulded core () and a flexible polyurethane skin layer (). The core itself comprises a moulded substrate layer () which is made of a substrate material, in particular a thermoplastic material, having a Shore A hardness higher than 60. The flexible polyurethane skin () is produced by a reaction overmoulding (ROM) process wherein a polyurethane reaction mixture is moulded in a closed mould () over at least a first area of the core surface. The moulded core () comprises in addition to said substrate layer () a softer material which is moulded onto the substrate layer () and/or onto which the substrate layer () is moulded. This moulded softer material has a Shore A hardness lower than 60 and forms a softer layer () between the flexible polyurethane layer () and the substrate layer () and/or a seal () engaging the internal wall of the mould () during the ROM process.
