Method for slush moulding articles, such as simulated leather or similar articles, of two or more colours from thermoplastic, thermosetting or elastomeric resins in powder form, the articles obtained and apparatus for implementing the method.

摘要

The method comprises, as a first stage, feeding a thermoplastic, thermosetting or elastomeric resin (10) in solid and preferably powder state into only a part (6) of the suitably preheated mould (2), this being achieved by separating the residual part in which a different colour is to be obtained, by the use of a special gasket (4). Said gasket is prepared by moulding, for example in the same mould (2), and is therefore able to perfectly follow the contour between the two colours. In the stage following the first filling, the mould is filled with powder material of the second colour and then emptied in accordance with the normal procedures of slush moulding. The mould (2), to which the two different colour materials have adhered to the required thickness, then passes to a further stage for completing gelling or fusion, before being cooled for extraction of the finished article.
