Abstract

Viene descritto un procedimento per lo stampaggio ad iniezione di resi, termoplastiche sintetiche (2), in cui, in una fase di iniezione durante la quale una resina termoplastica (2) portato allo sfato fluido è iniettata all'interno di uno stampo (3), viene introdotto all'interno della resina termoplastica (2) un flusso (15) di gas inerte (12) la cui distribuzione all'interno della resina termoplastica (2) viene controllata, durante la fase di riempimento di detto stampo (3) da parte della detta resina (2) mischiata al dello gas inerte (12), mediante una pluralità di sensori (16), alloggiati all'interno del detto stampo (3); viene inoltre descritta una apparecchiatura (1) per lo stampaggio ad iniezione di resine termoplastiche sintetiche (2) secondo il precedente procedimento.
