Izinto ezisetshenziswayo zeUkubumba umjovo wensimbi:
Inqubo ye-MIM isetshenziswa ezinhlobonhlobo zezinto ezisetshenziswayo, okuhlanganisa insimbi ephansi yengxubevange, insimbi engagqwali, insimbi yamathuluzi, ingxubevange ye-nickel base, ingxubevange ye-tungsten, ingxubevange eqinile, ingxubevange ye-titanium, izinto ezisetshenziswa kazibuthe, ingxubevange ye-Kovar, izitsha zobumba ezinhle, njll.
Hlobo luni lwemikhiqizo yensimbi efanelekileInqubo ye-MIM:
1. Isisindo sezingxenye ze-MIM ngokuvamile singu-0.2g - 200g.
2. Indawo ehlongozwayo ingamasentimitha-skwele ayi-100.
3. Ukunemba kosayizi wezingxenye ze-MIM ngaphezu kuka-10MM ngu-±0.5%.
4. Izingxenye ze-MIM ubukhulu obukhulu bodonga ngu-10MM.
5. Ubuncane bosayizi 0.2MM.

Ukubumba umjovo wensimbi kuyinto entshainqubo ye-powder metallurgy, ingakhiqiza ukuminyana okuphezulu nokuma okuyinkimbinkimbi izingxenye ze-sintered ngaphandle komshini. Ngezici ezihlukile zezinto ze-MIM, i-MIM iyakwazi ukukhiqiza izingxenye zensimbi ezinembayo zemikhiqizo ehlukahlukene, okuhlanganisa izimoto, omakhalekhukhwini, amathuluzi esandla, amathuluzi amazinyo, amathuluzi omoya, amathuluzi esandla samandla, amathuluzi okuhlinza, izimpahla zezemidlalo namakhompyutha aphathekayo. Izinto zensimbi ezisetshenziswa kakhulu kwinqubo ye-MIM yinsimbi engagqwali, insimbi eyingxubevange nezinto ezithambile zikazibuthe.
