Kupanga ndodo yabwino sikophweka ndipo kumafuna zinthu zingapo:
1. The screw ayenera kukhala pafupi kusesa lonse wononga mkati pamwamba, kuti apeze kutentha conduction wabwino, zotsatira kusakaniza ndi yopapatiza posungira nthawi yogawa.
2. Chilolezo cha radial pakati pa screw ndi mbiya (mbiya) chiyenera kukhala chochepera 0.003 kuwirikiza kwa screw.
3. Mapangidwe owongolera amatengedwa kuti apewe ngodya zakufa.
4. Pamene pulasitiki ili ndi tinthu tating'ono tating'ono tomwe timafunikira kupsinjika kwakukulu, ndikofunikira kuti musankhe omwazika kusanganikirana unit.Chigawo chosakaniza chobalalika chimatsimikiziranso kuti tinthu tating'onoting'ono tapulasitiki tating'ono ting'onoting'ono tisatengedwe mpaka kumapeto kwa screw.Chifukwa chake, mayunitsi osanganikirana ndi othandiza ngakhale mulibe tinthu tating'onoting'ono tapulasitiki.
5. Kukonzekera kwa gawo logawira kusakaniza kuyenera kuganiziridwa mozama kuti kuchepetsa kusiyana kwa kugwirizana ndi kusagwirizana kwa kutentha kwasungunuka.Malo okondedwa a gawo losakaniza ali kumapeto kwa screw.
6. Pamene pulasitiki ndi wandiweyani dzimbiri kulongedza katundu, monga corrosion dioxide, galasi ndi zina zotero, wononga ndi mbiya (mbiya) ayenera kupangidwa ndi zinthu kuvala zosagwira.
7. Pamene extrusion PVC, fluorine pulasitiki kapena zina akhoza poyera golide fumbi pamwamba dzimbiri pulasitiki, wononga, mbiya (mbiya) ndi makina mutu ntchito za dzimbiri zosagwira zipangizo kupanga.
8. Gawo losakanikirana liyenera kukhala ndi kutsika kwapansi kwapansi komanso mphamvu yabwino kwambiri yopopera patsogolo.
9. Pofuna kupititsa patsogolo kayendetsedwe ka kayendetsedwe kazinthu ndi kuchepetsa kupachika zinthu, utali wa fillet pansi pa ulusi uyenera kukhala wokulirapo, ndipo ulusi wambiri ndi phula laling'ono liyenera kupewedwa kuti muchepetse mikangano ndi kupititsa patsogolo mphamvu yotumizira. .
10. Chophimbacho chikakutidwa, chophimba chokhala ndi mikangano yochepa chiyenera kuperekedwa patsogolo.Izi zimathandizira magwiridwe antchito a screw, zomwe zimapangitsa kuti pakhale zokolola zambiri komanso kukhazikika bwino, ndipo wonongayo imakhala yosavuta kuyeretsa.
