Kutentha kotentha (extrudedChitoliro chachitsulo chosasinthika): kuzungulira chubu billet→kutentha→kuboola→atatu-mpukutu mtanda kugubuduza, mosalekeza kugudubuza kapena extrusion→kuvula→kukula (kapena kuchepetsa)→kuziziritsa→kuwongola→kuyesa kwa hydraulic (kapena kuzindikira zolakwika)→kulemba→yosungirako

Zopangira zopangira chitoliro chopanda msoko ndi chozungulira chubu billet, ndipo mluza wozungulira wa chubu uyenera kudulidwa ndi makina odulira kuti ukule ma billet kutalika pafupifupi 1 mita, ndikupita kung'anjo ndi lamba wotumizira.Billet amadyetsedwa mu ng'anjo kutentha, kutentha ndi pafupifupi 1200 digiri Celsius.Mafutawa ndi hydrogen kapena acetylene.Kuwongolera kutentha mu ng'anjo ndi nkhani yaikulu.Pambuyo pozungulira chubu kuchokera mu ng'anjo, iyenera kubayidwa kupyolera mu kubowola kokakamiza.

Nthawi zambiri, woboola wofala kwambiri ndi woboola magudumu a cone.Woboola wamtunduwu amakhala ndi magwiridwe antchito apamwamba, mtundu wabwino wazinthu, kukulitsa kwakukulu kwa m'mimba mwake, ndipo amatha kuvala mitundu yosiyanasiyana yazitsulo.Pambuyo kuboola, kuzungulira chubu billet motsatizana kutsatiridwa motsatizana mizere yozungulira mtanda, mosalekeza kugudubuza kapena extrusion.Pambuyo pa extrusion, chubu liyenera kuchotsedwa kuti liyike.Kukula pobowola mothamanga kwambiri ma rotary cone mu billet kupanga chubu.M'mimba mwake mkati mwa chitoliro chachitsulo chimatsimikiziridwa ndi kutalika kwa m'mimba mwake wakunja kwa kubowola kwa makina opangira.Chitoliro chachitsulo chikakula, chimalowa munsanja yozizirira ndipo chimakhazikika ndi kupopera madzi.Chitoliro chachitsulo chikakhazikika, chidzawongoledwa.

Pambuyo kuwongola, chitoliro chachitsulo chimatumizidwa ku chowunikira chachitsulo (kapena kuyesa kwa hydraulic) ndi lamba wotumizira kuti azindikire zolakwika zamkati.Ngati pali ming'alu, thovu ndi mavuto ena mkati mwa chitoliro chachitsulo, adzadziwika.Pambuyo pakuwunika kwabwino kwa mapaipi achitsulo, kusankha kozama kwamanja kumafunika.Pambuyo poyang'ana khalidwe la chitoliro chachitsulo, pentani nambala ya siriyo, ndondomeko, nambala ya batch yopanga, etc. ndi utoto.Ndipo adakwezedwa mnyumba yosungiramo katundu ndi crane..
