A process for the production by a moulding process of a micro-cellular or non- cellular elastomeric polyurethane skin layer or, more generally, to a process for the production of a composite comprising a first layer shaped part, which is made by a moulding process from a polyurethane reaction mixture, and a second layer shaped part which is adhered to the first part to form the composite. In order to avoid the use of release agents on the back side of the first layer shaped part, and thus the negative effect on the adhesion of the second layer shaped part, and the penetration of reaction mixture on this back side between the slides (9-10) of the mould, the mould surface (4) is covered on the back side of the moulding with a removable flexible covering (12), with a removable rigid pre-shaped covering or with a permanent non-stick coating layer.

L'invention concerne un procédé de production d'une couche de revêtement en polyuréthanne élastomère non cellulaire ou microcellulaire au moyen d'un procédé de moulage, ou plus généralement un procédé de production d'un composite renfermant une première partie en forme de couche qui est élaborée au moyen du processus de moulage à partir d'un mélange de réaction au polyuréthanne, et une seconde partie en forme de couche qui adhère à ladite première partie pour former le composite. En vue d'éviter l'utilisation d'agents de libération sur la face arrière de ladite première partie, et donc l'effet négatif sur l'adhésion de ladite seconde partie, ainsi que la pénétration du mélange de réaction sur cette face arrière entre les couches (9-10) du moule, la surface du moule (4) est recouverte sur la face arrière du moulage d'un revêtement souple amovible (12), d'un revêtement pré-formé rigide amovible (12) ou d'une couche de revêtement permanente non collante.
