Lo mugqa usetshenziswa kabanzi kuma-PVC granules kanye nokukhiqizwa kwezinhlamvu ze-CPVC. Nge-screw efanele, ingakhiqiza ama-PVC granules athambile wekhebula le-PVC, ipayipi elithambile le-PVC, ama-PVC aqinile wepayipi le-PVC, ukufakwa kwamapayipi, ama-CPVC granules.

Ukugeleza kwenqubo yalo mugqa njengokushaywa: Impushana ye-PVC + isengezo --- ukuxuba---isiphakeli sezinto ezibonakalayo--- i-conic twin screw extruder--- die --- pelletizer --- isistimu yokupholisa umoya --- isidlidlizi

Le extruder yomugqa we-PVC granulating isebenzisa i-extruder ekhethekile ye-conic twin screw kanye nesistimu ye-degassing kanye nesistimu yokulawula izinga lokushisa ngezikulufa kuzoqinisekisa ukwenziwa kwepulasitiki; I-pelletizer ibheke kahle ukuze ifane nobuso be-extrusion die; Isiphephetha-moya sizophephezela ama-granules kusisele ngokushesha ngemva kokuwa kwama-granules.
