Izinyathelo zokuvimbela ukushwabana kwediski yamabhuleki kanye nokuxega: insimbi encibilikisiwe ifakwa ngokulinganayo ku-sprue ukuze kuncishiswe ukushisa kwendawo kwediski futhi kuvimbele ukwakheka kwezindawo ezishisayo zokwenziwa. Ngokombono wokuqina okulinganiselayo kokuthungwa kwensimbi, lapho izingxenye ezincane ezinodonga oluncane kakhulu, inani lokushwabana liba likhulu, futhi kugcizelelwa kakhulu ekushwabaneni. Imodi yokudla ingaba ukuphakelwa kwesistimu yokugada noma ukuphakelwa kokuphakamisa. Lapho uhlelo lokuphakelwa lwesistimu yokugada selwamukelwa, ikhanda le-sprue lingakhushulwa ngokufanele, njengokwandisa ukuphakama kwebhokisi eliphezulu, ukwengeza indandatho yesango, njll.; I-cross runner iyiyunithi eyinhloko yokuskiya umoya nokuntanta. Uma isetshenziselwa isengezo sokushwabana, usayizi wesigaba sayo ungakhushulwa ngokufanele; I-sprue yangaphakathi kufanele ibe mfushane, ibe mncane futhi ibanzi. I-sprue yangaphakathi imfushane (i-sprue ephambene iseduze nokuthungwa). Ngenxa yethonya lokushisa lokuthungwa kanye ne-sprue ephambene kanye nomphumela wokugeleza kokugcwaliswa kwensimbi encibilikisiwe nokondla, i-sprue yangaphakathi ngeke iqine futhi ivalwe kusengaphambili, futhi izohlala ivuliwe isikhathi eside. Okuncane (ngokuvamile) kungavimbela ukwakheka kwamajoyinti ashisayo okuthintana ekungeneni kwe-sprue yangaphakathi. Ububanzi buwukuqinisekisa indawo eyanele yokuchichima. Uma ukuphonswa kungena esigabeni sokuqina esilinganiselayo sokwanda nokufinyela kwe-graphitization, insimbi encibilikisiwe e-ingate izoyeka ukugeleza futhi izoqina futhi ime ngesikhathi ukuze kuthuthukiswe izinga lokusetshenziswa kokuziphakela kwe-graphitization, okuwumphumela wokulungiswa oguquguqukayo we-ingate emfushane, encane nebanzi (intamo ye-riser) lapho iphakelwa. Kwezinye ukuphonswa okunokuncipha okukhulu, i-riser ingabekwa ukuze iphakelwe. I-riser ingcono kakhulu ekusethweni ekuqaleni kwe-sprue yangaphakathi, noma i-riser ingabekwa enkabeni ephakathi ukuze iphake idiski kolunye uhlangothi lwe-sprue yangaphakathi. Ezingxenyeni ezincane ezinezindonga ezincane, izinyathelo zokugoma zesibili zingathathwa, okungukuthi, i-inoculant ingafakwa ephaketheni elincane ukuze kuphakelwe ngokushesha ukuze kuthuthukiswe umphumela wokugoma futhi kukhuthazwe i-nucleation nokukhula kwe-graphite. Ingangezwa phansi kwephakethe bese igezwa ibe yinsimbi encibilikisiwe.
