Abstract (en)
[origin: WO2015097397A2] Process for preforming a semi-finished product (SP) made of plastic, in which: at least one anti-adhesive membrane (PM) is positioned facing a wall of a preforming mould (MP); the plastic semi-finished product (SP) is positioned facing the anti-adhesive membrane (PM), so that the anti-adhesive membrane (PM) is positioned between the semi-finished product (SP) and the wall; pressure is applied in order to press the semi-finished product (SP) against the wall of the preforming mould (MP), in order to give a shape to the semi-finished products (SP); the pressure ceases to be applied and the thus preformed part (PF) is injected from the wall; and the thus preformed part (PF) is removed from the mould.
