Amanyathelo okuthintela i-disc disc shrinkab kunye nokukhululeka: Intsimbi enyibilikisiweyo ingeniswa kwisitya ngokulinganayo ukunciphisa ukugqitha kwi-disc kwaye kuthintele ukumiswa kwamabala ashushu. Ngokwembono yokuqiniseka okulungeleleneyo kwe-Iron Disng, amalungu amancinci anqabileyo, owona mkhulu kwixabiso le-shrinkage, kunye nokugxininiswa ngakumbi kwi-shrinkage. Imo yokondla inokuba yindlela yokutsala inkqubo okanye ukondla okhubazayo. Xa ikhrayitheriya yokondla kwinkqubo yokutsala yenkqubo yamkelwa, intloko yeprue inganda ngokufanelekileyo, njengokukhulisa ukuphakama kwebhokisi ephezulu, ukongeza iringi yesango, njl. Imbaleki emnqamlezweni yeyona yunithi ye-skiming kunye nomoya odadayo. Xa isetyenziselwa ukongeza i-shrinkage, ubungakanani becandelo, isayiziya kwandiswa ngokufanelekileyo; I-Sprue yangaphakathi iya kuba mfutshane, ithambile kwaye ibanzi. I-Sprue yangaphakathi ifutshane (iprue inqamlezileyo ikufuphi ne-Collecting). Ngenxa yempembelelo ye-thermal yokuphosa kunye nepriwe eguqukayo kunye nesiphumo sokuhamba kwentsimbi egcwalisa kwaye ukondla, iprue yangaphakathi ayizukuqiniswa kwaye ivaliwe ixesha elide, kwaye iya kuhlala ingavalwanga ixesha elide. Mncinci (ngokubanzi) unokuthintela ukwenziwa kokudityaniswa koqhakamshelwano kwi-inlet yeprue yangaphakathi. Ububanzi kukuqinisekisa indawo eyaneleyo yokuphela. Nje ukuba ukuphoswa kwenqanaba lokuqiniswa kwegraphiriya kunye nokususwa, i-iron etyhidiweyo kwi-insest iyayeka ukuhamba kwaye iyeke ukulungiswa kwe-profaciting ye-gesic, intamo enobubanzi (intamo enobubanzi). Kwezinye iindawo zokulahla inkululeko enkulu, ukuphakama kunokubekwa ukondla. Ukuphakama kubaluleke kakhulu ekuqaleni kweSprue yangaphakathi, okanye ukuphakama kunokusetwa kwi-core ephakathi ukondla i-disc kwelinye icala leSprue engaphakathi. Kwiindawo ezinamanqanaba amancinci acocekileyo, amanyathelo onxweme aphezulu anokwamkelwa, oko kukuthi, inoculant inokongezwa kwiphakheji encinci yokuphucula ifuthe lokuphucula i-inoculation kunye nokukhuthaza i-yentection kunye nokukhulisa i-yecleite. Inokongezwa emazantsi ephakheji kwaye ihlambe kwi-molten iron.
