Izinyathelo zokuvimbela ukuncipha kwe-brake disc kanye nokuxega: insimbi encibilikisiwe ifakwa ku-sprue ngokulinganayo ukuze kuncishiswe ukushisa kwendawo ye-disc futhi kuvimbele ukwakheka kwezindawo ezishisayo zokwenziwa.Ngokombono wokuqiniswa okulinganiselwe kokusakazwa kwensimbi, izingxenye ezincane ezinezindonga ezincane kakhulu, likhulu inani lokuncipha, futhi kugcizelelwa kakhulu ukuncipha.Imodi yokudla ingaba ukuphakela kwesistimu yesango noma ukuphakela isikhuphukeli.Lapho uhlelo lokuphakelayo lwesistimu ye-gating lwamukelwa, ikhanda le-sprue lingakhuliswa ngokufanelekile, njengokwandisa ukuphakama kwebhokisi eliphezulu, ukwengeza indandatho yesango, njll;Umgijimi ophambanayo iyunithi eyinhloko yokushushuluza kanye nomoya ontantayo.Uma isetshenziselwa i-shrinkage supplement, usayizi wesigaba sayo ungandiswa ngokufanele;I-sprue yangaphakathi izoba mfushane, izacile futhi ibe banzi.I-sprue yangaphakathi ifushane (i-sprue evundlile iseduze nokubunjwa).Ngenxa yethonya elishisayo le-casting kanye ne-sprue eguquguqukayo kanye nomphumela wokugeleza wokugcwalisa nokuphakelwa kwensimbi encibilikisiwe, i-sprue yangaphakathi ngeke iqiniswe futhi ivalwe kusengaphambili, futhi izohlala ingavinjiwe isikhathi eside.Izacile (ngokuvamile) ingavimbela ukwakheka kwamalunga ashisayo athintanayo endaweni yokungena kwe-sprue yangaphakathi.Ububanzi buwukuqinisekisa indawo eyanele yokuchichima.Uma ukubunjwa sekungene esigabeni sokuqiniswa okunokulinganisela sokunwetshwa nokufinyezwa kwe-graphitization, insimbi encibilikisiwe ku-ingate izoyeka ukugeleza futhi izoqina futhi ime ngesikhathi ukuze kuthuthukiswe izinga lokusebenzisa i-graphitization self feeding, okuwumphumela wokulungisa oguquguqukayo womfushane, omncane. kanye ne-wide inite (i-riser neck) ekunceliseni.Kwamanye ama-casting anokuncipha okukhulu, isikhuphukeli singasethwa ukuze sidliwe.Isikhuphukeli sibekwe kahle kakhulu ekuqaleni kwe-sprue yangaphakathi, noma isikhuphukeli singasethwa phakathi nendawo ukuze sinikeze idiski ohlangothini olulodwa lwe-sprue yangaphakathi.Ezingxenyeni ezincane ezinodonga oluncane, izinyathelo ze-inoculation yesibili zingamukelwa, okungukuthi, i-inoculant ingafakwa ephaketheni elincane ukuze kufakwe i-inoculation ngokushesha ukuze kuthuthukiswe umphumela we-inoculation futhi kukhuthaze i-nucleation nokukhula kwe-graphite.Inganezelwa phansi kwephakeji futhi igezwe ibe yinsimbi encibilikisiwe.
