Document Type and Number:
WIPO Patent Application WO/2011/145071
Kind Code:
A3
Abstract:
The present invention relates to a plant for producing molded pieces with reactive mixtures, such as two-component polyurethane, with thermoplastic polymers, and with both said materials to produce the same piece, comprising: · one or more mold-holders (7, 7a, 7b, 7c); • one or more presses (302, 304), each of said presses being provided with an injector for thermoplastic polymers (303, 305); • one or more injectors for reactive mixtures (306, 307); and is characterized in that · each of said one or more mold-holders (7, 7a, 7b, 7c) is suitable to receive one or more molds (1a,s, 1ad); • each of said molds (1as, 1ad) comprises two or more half-molds (3as, 4as, 3ad, 4ad), said half-molds mutually interfacing at surfaces P, to form a closed cavity, and said joining surfaces P forming gaps which, when said mold (1as, 1ad) is in the operating position, are not present in the top part of said cavity.
