Ukubumba inaliti yomgubo wesinyithi lisebe lesinyithi kunye nesayensi yezixhobo. Inkqubo ikakhulu isebenzisa umgubo wentsimbi njengento ekrwada kwaye isebenzisa indlela "yokwenza + i-sintering" ukwenza izinto kunye neemveliso. Yinkqubo ekufutshane yokubumba umnatha ukuvelisa iinxalenye ezinzima ngexabiso eliphantsi. Ngokutsho kokuhlelwa kwezinto, i-powder Injection inokwahlulwa ibe yi-MIM (i-Metal Injection Molding) kunye ne-CIM (i-Ceramic Injection Molding) iindidi.
Isondlo sokubumba inaliti yesinyithi yintlaka edityanisiweyo yomgubo wesinyithi ocolekileyo kunye nomxholo weoksijini ophantsi kunye nesphericity elungileyo ngokongeza imathiriyeli yepolymer ukwenza iyunifomu yomgubo. Inomanzi aphezulu, ingxinano ye-sintering ephezulu, ukomelela okuphezulu okubanzi, ukuqina okuhle, isiphumo sokupholisha njengesipili kunye nezinye iipropathi. Isondlo sokubumba isitofu sesinyithi sisetyenziswa ikakhulu kwiimveliso zokubumba inaliti yentsimbi kwiindawo zeselfowuni, iitheminali ezinxitywayo ezikrelekrele, iinxalenye zemoto, izixhobo zonyango, iindawo ze-aerospace kunye nezinye iinkalo.
Amacandelo alungiselelwe yinkqubo ye-MIM asetyenziswa ngokubanzi kwiinkalo ze-aerospace, imboni yemoto, ukukhusela ilizwe, unxibelelwano lwe-elektroniki, unyango lwezonyango, oomatshini kunye nokunye. Ibe yitekhnoloji ephezulu kunye nentsha kwi-powder metallurgy kunye nentsimi yezoshishino kunye nophuhliso olukhawulezayo kwiminyaka yakutshanje. Imarike ye-MIM yehlabathi kulindeleke ukuba ikhule ukusuka kwi-3.1 yeebhiliyoni zeedola ngo-2018 ukuya kwi-4.5 yeebhiliyoni zeedola ngo-2023.
Imarike ye-MIM yaseTshayina yaqala ukukhula kancinci ukusukela ngo-2000. Kwisithuba nje seshumi leminyaka, imakethi ye-MIM yasekhaya ibonise umfutho owomeleleyo wophuhliso. Ngokweenkcukacha-manani zePowder Metallurgy Association of China Steel Association, isikali seMIM sasekhaya sigqithile kwibhiliyoni enye yeyuan ngo-2011, kwaye isikali semalike safikelela kwi-4.85 yeebhiliyoni zeeyuan ngo-2015, sibalelwa kwi-35.23% yesikali semarike ye-MIM yehlabathi. Ngo-2019, isikali semakethi ye-MIM yasekhaya sinyuke saya kutsho kwi-8.4 yeebhiliyoni zeeyuan, ukukhula konyaka-ngonyaka ngama-20%. Imakethi ye-MIM yaseTshayina iphuhlile yaba yinxalenye ebalulekileyo yemarike ye-MIM yehlabathi.
