Ibisobanuro bitandukanye hamwe na moderi ya PVC twin-screw extruder irashobora kubyara imiyoboro ya diametre zitandukanye nubunini butandukanye bwurukuta. Ibikoresho byabugenewe byabugenewe hamwe na plastike imwe hamwe nibisohoka byinshi. Ibishushanyo mbonera bikozwe mubyuma byujuje ubuziranenge, imiyoboro yimbere yimbere ya chrome isahani, kuvura neza, kwambara no kurwanya ruswa; hamwe nubushakashatsi bwihuse bwihuse, ubunini bwumuyoboro nibyiza. Imashini idasanzwe kumuyoboro wa PVC ifata igikoresho kizunguruka gifata, kidasaba gusimbuza ibice na diameter zitandukanye. Hamwe nigikoresho cyo gukata, gukata, gutondagura, kubumba intambwe imwe. Shigikira imashini itabaza kumurongo.
