Abstract
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.
