Method and mould for manufacturing a moulded article comprising at least an elastomeric polyurethane skin |
摘要 |
For manufacturing a moulded article comprising at least an elastomeric polyurethane skin ( 9 ) and optionally a structural backing layer ( 10 ) and an intermediate foam layer ( 12 ) a mould is used having at least a first mould part ( 1 ) comprising at least two mutually movable mould sections ( 2 - 4 ). The skin ( 9 ) is moulded with its front against a surface ( 7 ) of the first mould part ( 1 ) by applying at least one reactive polyurethane mixture to this mould surface. In order to prevent the seam between the mutually movable mould sections ( 2 - 4 ) of the first mould part to leave traces on the front of the moulded skin ( 9 ), the first mould part ( 1 ) further comprises a removable, flexible liner ( 6 ) which is positioned onto these mould sections to cover at least partially the seam therebetween. Since the first mould part ( 1 ) comprises mutually movable mould sections ( 2 - 4 ), the design freedom is increased and it is not required to transfer the skin to another mould for providing relatively rigid backing layers to the back of this skin.
