Abstract

Thermoplastic article having two relatively movable parts is formed by moulding the first part using a first thermoplastic and then moulding onto it the second part using a second thermoplastic. The second thermoplastic is selected so that it doesn't stick to the first thermoplastic and moulding of the second part is at a sufficiently low temp. that the first part doesn't melt. The method is used for moulding buckles used for garments or shoes. The moulding of a buckle is simplified and thereby cheaper as special bearing sockets for the tongue don't have to be used to prevent the tongue axle from sticking to the bearing housing of the surrounding frame.
