For manufacturing the composite automotive trim part a flowable skin material (1) is applied onto a first mould surface (4), a flowable substrate material (2) is applied onto a second mould surface (7), the mould (5,8) is closed and a foamable material (3) is applied in the gap between the flexible skin (1) and the rigid substrate (2). Both the flexible skin and the rigid substrate can be manufactured by spraying a polyurethane reaction mixture. Advantages are that no positioning of the rigid substrate nor of the flexible skin is required and that especially the rigid substrate has not to be manufactured separately thus enabling to reduce the production costs and to increase the part quality. The sealing of the mould cavity for producing the foam layer is achieved by providing a sufficiently thick layer of flexible skin material in the zone of contact with the substrate. Installation and tool costs can be reduced by separating both mould halves and producing the skin and the substrate along different production lines. <IMAGE> |
