Hot adagulung'undisa (extrusion seamless chitsulo chitoliro): chubu chozungulira → kutentha → perforation → → kugubuduza katatu, kugudubuza kapena kutulutsa → kutsekedwa → kukula (kapena kuchepetsa) → kuzizira → kuwongolera mayeso a hydraulic (orflaw) → tag → yosungirako.

Kugudubuza chubu cha zopangira ndi chubu chozungulira, mazira a chubu amadutsa pamakina odulira kuti adule kukula kwa digirii pafupifupi mita 1, ndikutumizidwa ndi kutentha kwa ng'anjo ya conveyor lamba.Billet amadyetsedwa mu ng'anjo yotentha, kutentha kumakhala pafupifupi madigiri 1200 Celsius.Mafuta a hydrogen kapena acetylene.Kuwongolera kutentha kwa ng'anjo ndikofunikira kuti muvale ma chubu a air chubu mozungulira, mutatha kutulutsidwa kwa puncher.zomwe nthawi zambiri zimakhala zofala kwambiri pa puncher tapered roller nkhonya izi, kupanga bwino kwambiri, mtundu wazinthu, kuchuluka kwa perforated, kuvala zitsulo zosiyanasiyana.Pambuyo pobowola, chubu chozungulira chakhala chopindika chamipukutu itatu, kugudubuza kapena kutulutsa.Pambuyo extrusion kuchotsa chitoliro sizing.Sizing mphero ndi kusinthasintha kothamanga kwa chulucho kubowola mu nkhonya ya Billet kupanga chitoliro chachitsulo.The zitsulo chitoliro m'mimba mwake anatsimikiza ndi kutalika kwa awiri akunja a sizing mphero kubowola.Pambuyo sizing, chitoliro zitsulo kulowa kuzirala nsanja ndi madzi kutsitsi kuzirala, chitsulo chitoliro pambuyo kuzirala, m`pofunika kuwongola.Kutumizidwa ndi chitoliro cha conveyor powongola makina ozindikira zitsulo (kapena kuyesa kwa hydrostatic) kuti achite cholakwika chamkati.Zitsulo chitoliro nkhani mkati monga ming'alu, thovu adzakhala wapezeka.Kuyang'ana kwabwino kwa chitoliro chachitsulo komanso posankha mozama pamanja.Chitoliro chachitsulo cha Quality Kuyang'anira, Kuyang'ana, gwiritsani ntchito utoto wopopera pa nambala, kukula, gulu lopanga.Ndi galimoto ya chingwe yomwe ikulendewera m'nyumba yosungiramo katundu.
