(1) Njira yopangira zitsulo
Zitsulo zimapangidwa ndi ng'anjo yamagetsi, chosinthira oxygen kapena njira yotseguka yamoto.
(2) Njira yopanga chubu yopanda kanthu
Chubu chopanda kanthu chikhoza kupangidwa ndi njira yotentha yozungulira, ndipo billet yosalekeza kapena ingot yachitsulo ingagwiritsidwenso ntchito.
(3) Kupanga njira yachitsulo chitoliro
Chitoliro chachitsulo chikhoza kupangidwa ndi kugudubuza kotentha (extrusion, kukulitsa) kapena kujambula kozizira (kugudubuza) njira yopanda phokoso.

(1) Mayeso a Hydraulic
Chitoliro chachitsulo chiyenera kuyesedwa ndi hydraulically mmodzimmodzi.
(2)Mayeso osalala
Mapaipi achitsulo okhala ndi mainchesi akunja opitilira 22mm mpaka 400mm ndi makulidwe a khoma osapitilira 10mm adzayesedwa kuphwanyidwa.
(3)Kuyesa kwamphamvu
Chitoliro chachitsulo chokhala ndi makulidwe a khoma osapitirira 8 mm chikhoza kuyesedwa pamoto ndi taper pamwamba pa 30 °, 45 ° kapena 60 °.
(4) Mayeso opindika
Mapaipi achitsulo okhala ndi mainchesi akunja osapitilira 22 mm adzayesedwa kupindika.
(5)Kuyesa kosawononga
Malinga ndi zofunikira za wogula, chitoliro chachitsulo chidzayesedwa ultrasonically mmodzimmodzi.
Mawonekedwe amkati ndi akunja a chitoliro chachitsulo alibe ming'alu, mapindikidwe, ma creases, crusting kapena kupatukana, ndipo zolakwikazi ziyenera kuchotsedwa kwathunthu.Kuzama kwachilolezo sikuyenera kupitirira kupatuka koyipa kwa makulidwe a khoma, ndipo makulidwe enieni a khoma pa malo oyeretsera sangakhale ochepa kuposa omwe amaloledwa ndi khoma.
Kuyika, kuyika chizindikiro ndi mawonekedwe apamwamba a mapaipi achitsulo azitsatira zomwe GB/T 2102 ikupereka.
