Abstract
A horizontal press for the injection of thermoplastic materials comprises a first and a second half-mold forming a mold. The press (1) further comprises a feed screw (18) that can be rotated around its own axis of development (X) for introducing a solid thermoplastic material and feeding it to heating means (15), the heating means (15) melting the thermoplastic material; the feed screw (18) can be shifted so as to inject the melted thermoplastic material into the mold; a first mechanical transmission (24) for shifting the feed screw (18) along its own axis of development (X) and a second mechanical transmission for rotating the feed screw (18) around its own axis of development (X).
