    • Method to obtain polymeric products such as containers, automatic dispensers, casings, tanks, etc., which have zones with a differentiated conductivity and/or localised surface zones characterised by a specific treatment of enrichment and/or surface finishing, the products being obtained by moulding of a polymeric substance (13) such as polyurethane or a thermoplastic material or another analogous material, the method employing particles (14) of a conductive type having the desired functional properties, the conductive particles (14) being introduced into the mould (11) and being subjected there to the action of migrating forces, which cooperate with the inner walls of the mould (11) and which displace the particles (14) towards at least one preferred and pre-determined zone of the mould (11). Device suitable to carry out the above method and comprising a mould (11) into which are injected polymeric substances (13), the device comprising at least means (28) for the electrostatic charging of the conductive particles (14) and acting on those particles before their introduction into the mould (11), the device comprising also at least one source suitable to create a field attracting those conductive particles (14) at least at one pre-determined zone of the walls of the mould (11).
