Lo mgca usetyenziswa ngokubanzi kwi-PVC granules kunye ne-CPVC imveliso ye-granules. Nge-screw efanelekileyo, inokuvelisa i-PVC granules ethambileyo yentambo ye-PVC, ithumbu elithambileyo le-PVC, i-PVC granules eqinile yombhobho we-PVC, ukufakwa kombhobho, iigranuli ze-CPVC.

Ukuhamba kwenkqubo yalo mgca njengokuvuthela: PVC powder + additive --- ukuxuba---isondlo sezinto eziphathekayo--- conic twin screw extruder--- die --- pelletizer --- inkqubo yokupholisa umoya --- vibrator

Le extruder of PVC umgca granulating amkele okhethekileyo conic twin screw extruder kunye nenkqubo degassing kunye nenkqubo yokulawula ubushushu screw uya kuqinisekisa plasticization impahla; I-pelletizer ixutywe kakuhle ukuze ihambelane ne-extrusion die face; Isivutheli somoya siya kuvuthela iigranules kwisisele ngoko nangoko emva kokuba iigranuli ziwile.
