Mzerewu umagwiritsidwa ntchito kwambiri popanga ma granules a PVC ndi ma granules a CPVC. Ndi screw yoyenera, imatha kupanga ma granules ofewa a PVC a chingwe cha PVC, payipi yofewa ya PVC, ma granules olimba a PVC a chitoliro cha PVC, zolumikizira mapaipi, ndi ma granules a CPVC.

Njira yoyendetsera mzerewu ngati kuphulika: Ufa wa PVC + zowonjezera --- kusakaniza--- chakudya cha zinthu--- chotulutsira ma screw awiri a conic--- die --- pelletizer --- dongosolo loziziritsira mpweya --- vibrator

Chotulutsira mpweya cha PVC ichi chimagwiritsa ntchito chotulutsira mpweya chapadera cha conic twin screw ndipo makina ochotsera mpweya ndi makina owongolera kutentha kwa screw adzaonetsetsa kuti zinthuzo zipangidwe pulasitiki; Pelletizer imakonzedwa bwino kuti igwirizane ndi nkhope ya extrusion die; Chophulitsira mpweya chidzaphulitsa granules mu silo nthawi yomweyo granules zitagwa.
