Kuponyera mchenga wobiriwira sikufunikira kuwuma ndipo kumatenga bentonite ngati binder. Chinthu chofunika kwambiri cha mchenga wobiriwira ndi chakuti sichiyenera kuuma ndi kulimba, pamene chimakhala ndi mphamvu yonyowa. Ngakhale mphamvuyo ndi yochepa, imakhala ndi retreatability bwino ndipo ndi yosavuta kugwedeza; komanso, ndiwobiriwira mchenga kuponyera ndondomekoali ndi ubwino angapo mkulu akamaumba Mwachangu, yochepa kupanga mkombero, otsika mtengo zinthu ndipo n'zosavuta kulinganiza otaya kupanga. Komabe, chifukwa nkhungu ya mchenga siimauma, kutentha kwa chinyezi ndi kusamuka kumawonekera pamwamba pa nkhungu yamchenga panthawi yoponyera, zomwe zimapangitsa kuti kuponyera kumakhala ndi ma blowholes, mchenga, mchenga, mchenga womata ndi zolakwika zina zoponyera.
Kuti apereke zonse kusewera ubwino wobiriwira mchenga akamaumba ndi kusinthakhalidwe la castings, m'pofunika kusunga khola akamaumba mchenga ntchito, yaying'ono ndi yunifolomu nkhungu mchenga ndi wololera kuponyera ndondomeko pa ndondomeko kupanga. Choncho, chitukuko cha luso wobiriwira mchenga akamaumba wakhala kugwirizana kwambiri ndi chitukuko cha akamaumba makina ndi akamaumba luso.
Posachedwapa, kuumba kwa mchenga wobiriwira kwapangidwa kuchokera ku makina wamba kupita ku makina osakanikirana kwambiri. Kuchuluka kwa kuumba, kuphatikizika kwa nkhungu zamchenga, komanso kulondola kwa mawonekedwe akuchulukirachulukira, pomwe kuchuluka kwa roughness kwa ma castings kukucheperachepera.Njira yopangira mchenga wobiriwira (popanda utoto) imatha kupanganso zitsulo zolemera ma kilogalamu mazana angapo.
Mchenga wobiriwira nthawi zambiri umapangidwa ndi mchenga watsopano, mchenga wakale, bentonite, addenda ndi madzi okwanira. Pamaso kupanga chiŵerengero cha akamaumba mchenga m`pofunika kudziwa ntchito osiyanasiyana ndi kulamulira chandamale mtengo wa akamaumba mchenga malinga ndi mtundu wa aloyi anatsanulira, makhalidwe ndi zofunika za kuponyera, akamaumba njira ndi ndondomeko ndi kuyeretsa njira. . Pambuyo pake, malingana ndi mitundu yosiyanasiyana ya zipangizo zosiyanasiyana, njira yopangira mchenga, zipangizo, mchenga ndi chitsulo chiŵerengero ndi chiŵerengero cha kutaya kwa zinthu zosiyanasiyana zimagwiritsidwa ntchito popanga chiŵerengero cha mchenga. Zizindikiro zaumisiri ndi kuchuluka kwa mchenga wowumba zitha kudziwikiratu pambuyo potsimikizira kupanga kwanthawi yayitali.
