Mu myaka yashize, inganda zishushanyije zateye imbere cyane, kandi gukina byateguwe biroroshye gukora, ubuziranenge, kandi nta bisigara biri muri casting ubwayo. Kugirango wuzuze ibiranga hejuru, ibishushanyo hamwe nubunini bwa grafite bigomba guhitamo uburenganzira bwo gutunganya, uyumunsi Furuite graphite xiaobian izakubwira kubyerekeranye nibiranga ibishusho hamwe na grafite nini:
Ibiranga flake grafite ya mold (FIG. 1)
Ubwa mbere, coefficente yubushyuhe bwa mold flake grafite ni ndende. Umuvuduko wo gukonjesha urihuta kandi casting irashobora gukurwaho vuba ukoresheje ibishushanyo mbonera.
Babiri, hamwe nimbaraga runaka yubukanishi. Iyo ubushyuhe bwa casting buri hejuru, ifu igomba kugumana imiterere yabyo, kugirango casting ikorwe neza.
Icya gatatu, coefficente yo kwagura ubushyuhe ni nto, ingaruka zo kurwanya ubushyuhe zirakomeye. Imiterere yubunini nubunini bihinduka ni bito iyo bishyushye kandi bikonje, biroroshye rero kugumana neza neza gukina.
Bane, gira imikorere myiza yo gutunganya.
Icya gatanu, grafite oxyde muri gaz ihindagurika, igihangano ntigishobora gusigara ibisigisigi.
