Ma die castings amagwiritsidwa ntchito kwambiri m'mafakitale ambiri, makamaka pakupanga magalimoto ndi ndege, chifukwa cha zabwino zotsika mtengo, kupanga nthawi imodzi, komanso kuthekera kopanga magawo akulu okhala ndi zovuta.Pa ndondomeko kuponyera, ena kufa castings adzakhala ndi zilema, monga zonyansa oxidized, mabowo kuwira, shrinkage porosity, ming'alu, etc. Zopunduka izi zimakhudza ntchito ndi moyo utumiki wa castings kufa, ndipo zingachititse ngozi angathe ntchito, makamaka kupanga. mafakitale monga magalimoto ndi ndege.Zotsatira za ngozi zomwe zingatheke ndizovuta kwambiri.
Kuti atsimikizire mtundu wa ma kufa castings, opanga ayenera kuchita mayeso asayansi ndi okhwima a kufa castings.Pali njira zambiri zodziwira za kufa castings.Kwa zolakwika zina zamkati zomwe sizingadziwike ndi njira wamba, kuyesa kwa X-ray kosawononga ndikoyenera.Imatha kuzindikira mawonekedwe amkati ndi zida zamakina popanda kuwononga chinthu choyang'aniridwa.Izi zimapangitsa kuti zolakwika zambiri ziziwoneka bwino mukangoyang'ana, ndipo zimakhala ndi mawonekedwe anzeru komanso osavuta kuwunika bwino komanso kuchuluka kwa zolakwika.
Chowunikira cha Whale chokhazikika chokhazikika chodziyimira pawokha ndikupangidwa ndi Haobo chimapangidwa mwapadera kuti chigwiritsidwe ntchito pazida zowunikira zida zakufa.Ndi chojambulira chojambulira chaphokoso chotsika.Gulu lakutsogolo la chojambulira limapangidwa ndi ukadaulo wa amorphous silicon (a-Si), chojambulira chojambulira chogwiritsira ntchito ukadaulo wa amorphous silicon, womwe uli ndi mawonekedwe amtundu wapamwamba wazithunzi, mitundu yayikulu yosinthika ndi mitundu yosiyanasiyana ya ma terminal.Mapangidwe amtundu wokhazikika ali ndi magiya osinthika osinthika ambiri, omwe amawapangitsa kukhala oyenera pazogwiritsa ntchito zowoneka bwino komanso zochitika zazikulu zosiyanasiyana.
