<p>A method for realising thermoplastic products, comprising: use of a granular material comprising granules of thermoplastic polymers; inserting a dose (M) of the granular material internally of the chamber (11) of a mould (10); compression of the dose (M) of granular material contained in a chamber (11) of the mould (10); heating an internal surface of the chamber (11) of the mould (10) during the compression up to producing a softening of the thermoplastic granules at least of a most external layer of the dose (M) of granular material compressed in the chamber (11); before the stage of compression and heating, the method includes covering at least a portion of an external surface of the dose (M) of granular material with an opaque film, which film comprises at least an opaque portion such as visually to hide the material covered thereby.</p> |
