Processus fingendi extrusio fistulae plasticae in tres gradus dividitur;
I. Plasticization rudis materiae. Hic processuspotest facere materiae solidae vertere in viscosum fluidum uniformeper calefactionem et mixtionem extruder;
II.formans. Under the *officiumde extrusionem partiumtille extraneus, materia fusilis per caput formans continue in quadam pressione et velocitate transit, ut figuram quandam sectionis transversalis obtineat;
III.Refrigerant etcalibratiis. Tet liquefaciens materia potest figere nactus figuram percalibratiiset refrigeratio curatio, et solida (plastic pipe) fiunt.
Praemissae tres gradus principales fiuntmachinaet auxiliamachina, id estextrusio unitatis. Speciatim principalis machina est extruder, machina auxiliaris ex capite;calibratiisfabrica, refrigeratio fabrica, tractio fabrica, fabrica incisio et positio pectora.
