Uru ruhererekane ni imashini ifunga umuringa wo gufunga, ikwiranye no kugabanuka no guteka ibyuma bitandukanye byumuringa wumuringa, ibikoresho byuma nibindi bicuruzwa bifite ubunini bunini.
1. Imashini ikoresha imirasire yubushyuhe bwo kugabanya ubushyuhe, hamwe nubushyuhe bwo gushyushya hejuru, hepfo, ibumoso n iburyo kugirango ushushe icyarimwe. Ifite kandi ibikoresho byinshi byihuta byihuta byumuyaga, bishobora gukurura icyarimwe ubushyuhe mugihe cyo gushyushya, bigatuma agasanduku kose mubushyuhe buhoraho; irashobora gutuma ibicuruzwa bisaba kugabanuka kwubushyuhe no guteka gushyuha icyarimwe icyarimwe, kugumana imiterere yumwimerere yibicuruzwa, kwirinda guhindagurika no guhindura ibara nyuma yubushyuhe bwo kugabanuka no guteka, no kwemeza ubuziranenge buhamye;

3. Imiterere ya aluminium alloy imiterere yuburyo butuma ibipimo byubukanishi bihinduka kandi bigahinduka uko bishakiye, kandi icyitegererezo gifite imiterere ihinnye kandi ishushanyije neza. Irashobora kandi kwimurwa no guhuzwa numurongo wo gukora kugirango ugenzure;
4.
5. Igenzura ryigenga agasanduku k'amashanyarazi, kure yubushyuhe bwo hejuru; Igishushanyo mbonera cyibisanduku bishyushya byashyizwemo ipamba yubushyuhe bwo hejuru (ubushyuhe bwa 1200 ℃) hagati, birinda ubushyuhe bwo hanze bwakazu gushyuha, ntibituma gusa akazi gakorwa neza, ariko kandi igabanya imyanda.
