Ukubumba inaliti yentsimbi yinto entshainkqubo metallurgy umgubo, inokuvelisa uxinaniso oluphezulu kunye nemilo entsonkothileyo yezahlulo ze-sintered ngaphandle komatshini. Ngeempawu ezikhethekileyo zezixhobo ze-MIM, i-MIM iyakwazi ukuvelisa iinxalenye zetsimbi ezichanekileyo kwiimveliso ezahlukeneyo, kubandakanywa iimoto, iifowuni eziphathwayo, izixhobo zesandla, izixhobo zamazinyo, izixhobo ze-pneumatic, izixhobo zezandla zamandla, izixhobo zotyando, iimpahla zemidlalo kunye neekhomputha zelaptop. Izinto zetsimbi ezisetyenziswa ngokuqhelekileyo kwinkqubo yeMIM yintsimbi engenasici, intsimbi yealloy kunye nezinto ezithambileyo zamagnetic.
