Kuri OGM pellet urusyo: OGM-0.8, OGM-1.5, OGM-6, nibindi.
Ukurikije ibyifuzo byabakiriya cyangwa ibishushanyo bihuye, turashobora gutunganya impeta ipfa hamwe na moderi zitandukanye hamwe na aperture zitandukanye.
Impeta ipfa umwobo ifite ubuso bwiza bwo kurangiza, gukora granulation nziza, kugaragara neza kurangije, guturika gake, imiterere yibintu byiza, kugabanya ifu yifu, kugabanuka neza nibisohoka byinshi. Umusaruro ukora neza mubisobanuro bimwe urarenze cyane ugereranije nurungano.
Ubworoherane bwurukuta rwumwobo rwimpeta ipfa kugaburira ibiryo bigabanya ubukana bwibintu byinjira mu mwobo, bigira akamaro mu kuzamura umusaruro wa granulation yibikoresho binyuze mugutezimbere ibikoresho: inguni yimpeta ipfa kugaburira ibiryo ni kimwe, kwemeza uburinganire bwiza bwimpeta ipfa gusohoka.
Kugirango ubuzima bwiza na serivisi ubuzima bwimpeta bipfe, itandukaniro riri hagati yuburemere bwimpeta ya 46Cr13 bipfa HRC52-55 nibindi bice ntibishobora kurenza HRC2.
Impeta ipfa gushyuha ku bushyuhe bwo hejuru (1050 °) ikazimwa no gukonja vuba. Muri iki gikorwa, umubiri upfa uzagira ihinduka rito rya 0.3 ~ 1.0mm. Ikosa ryibanze ryimpeta ipfa irashobora kugera kuri 0.05 ~ 0.15m binyuze mu gusya.
