    • 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.
    • 为了制造包含至少弹性体聚氨酯表层(9)和任选的结构背衬层(10)和中间泡沫层(12)的模制品,使用具有至少第一模具部件(1)的模具,所述第一模具部件(1)包括至少两个 相互移动的模具部分(2-4)。 通过将至少一种反应性聚氨酯混合物施加在该模具表面上,使其表面(9)以其前部模制在第一模具部件(1)的表面(7)上。 为了防止第一模具部件的相互移动的模具部分(2-4)之间的接缝在模制表皮(9)的前部留下痕迹,第一模具部件(1)还包括可拆卸的柔性衬里 (6),其被定位在这些模具部分上以至少部分地覆盖它们之间的接缝。 由于第一模具部件(1)包括相互移动的模具部分(2-4),所以设计自由度增加,并且不需要将皮肤转移到另一个模具,以在该皮肤背面提供相对刚性的背衬层。
