摘要： Cast moulding process of a product (1) comprising at least two overlapped layers (10, 11) of expansible plastic materials (Mi, Ms), said plastic materials (Mi, Ms) being cast in a sequence into a mould (2). According to the invention, after the casting of the material (Mi) for the first layer (10; 11) but before the casting of the material (Ms) for the second layer (11) of said product (1), between the first (20; 21) and the second (21) half shell of said mould (2), a junction element (12) retained all about by the edges, clamped to each other, of said half shells (20; 21), is inserted. The junction element (12) is compatible or made compatible for the adhesion to the upper surface of the material (Mi) of the first layer (10; 11) and to that lower of the material (Ms) of the overlying second layer (11) during the curing of said materials (Mi, Ms). Said first layer (10; 11) and second layer (11) are two consecutive and overlapped layers of a possible sequence of two or more layers (10; 11). Among the advantages there is the elimination of part of the moulding equipment and a significant shortening of the forming times. The process is particularly useful for the forming of footwear soles with multiple layers of synthetic material; in particular polyurethane.
