I-conical twin screw barrel ibambe izikulufu ezimbili ezicijile zihlangene emgqonyeni amabhobo awo aminyene ukusuka ekugcineni kokuphakelayo kuye endaweni yokufa. Leyo taper iwumklamo wonke. Inikeza ukuthathwa okukhulu kwempushana ye-low-density, ukucindezelwa okwakhiwa kancane kancane esikhundleni sokuzuma, kanye nokucindezela okukhuphukayo ekuphumeni okufushane. Umphumela uba ukucindezelwa kancane kancane, ukugunda okuthambile, kanye nokudlulisa okuqinile, okuyikhona kanye okuzwela ukushear nokuzwela ukushisa njengesidingo se-PVC esiqinile.

I-parallel twin screw barrel ibamba izikulufu ezimbili ezinobubanzi obungashintshi zihambisana ku-figure-8 bore. Izikulufu ziyajika ndawonye futhi ziphushele into phambili ngokuyivalela phakathi kwezindiza, kunokuyihudulela odongeni ngendlela isikulufu esisodwa esenza ngayo. Izinketho ezimbili zedizayini zinquma ukuthi umshini ungenzani: isiqondiso sokuzungezisa (ukuzungezisa ngokuhlanganyela noma ukuzungeza) kanye nokujula kwemeshi yezikulufu (ngokugcwele, ngokwengxenye, noma cha). Thola lezo zinhlanganisela ezimbili ezilungile nezifanayo zehadiwe, izimbobo, noma i-PVC eqinile ephuma ngaphandle.
