Kuthiwani Ngenqubo Yokubumba Umjovo Wensimbi

Ukubumba umjovo we-Micro metal powderindlela: Insimbi ye-MIMukubumba umjovo we-powderIndlela iwubuchwepheshe obusebenzisa ingxube yempushana yensimbi ecolekileyo kanye ne-resin noma i-wax (i-binder) njengezinto ezingavuthiwe zokubumba umjovo wensimbi bese i-degreasing (ibola i-binder) kanye ne-sintering ukukhiqiza imikhiqizo yensimbi. , Ingabe inqubo yokukhiqiza eyinhlanganisela ehlanganisa i-powder metallurgy kanye nokubumba komjovo wepulasitiki. Ingasebenzisa impushana yensimbi ecolekileyo kakhulu kunaleyoi-powder metallurgy, ngakho-ke ingakwazi ukukhuthaza i-sintering ukukhiqiza izinto zokuminyana okuphezulu, futhi ukusebenza komkhiqizo kuthuthukiswa kakhulu. Ingakwazi futhi ukukhiqiza izingxenye zensimbi ezincane ezinobunjwa obuyinkimbinkimbi kanye nokunemba okuphezulu. Muva nje, indlela yokubumba umjovo we-micro metal powder iye yathuthukiswa ngempumelelo.

IUmkhiqizi we-MIMinezinzuzo ezinhlanu ezilandelayo:

1. I-finer metal powder kanye ne-binder kukhethwa ukwenza izingxenye, futhi impahla eluhlaza inoketshezi oluphezulu.
2. I-homogenization yezikhala zempahla eluhlaza ibonakala ngokuxuba kanye ne-granulating.
3. Ukusetshenziswa kobuchwepheshe bokukhiqiza isikhunta sensimbi ye-microporous kuye kwathuthukisa ukugcwaliswa kwezinto ezibonakalayo, ukuzinza kokubumba, ukukhishwa kwesikhunta kanye nezakhiwo zokudlulisa.
4. Isivinini sokushisa siyanda ngesikhathi senqubo yokubopha kanye ne-sintering, engalawula ukukhula kwezinhlamvu zekristalu futhi ivimbele ukuguquguquka nokulimala ngesikhathi sokuncipha.
5. Ubuchwepheshe bokuhlola obunembayo busungulwe ohlelweni lokuhlola.

Inqubo yokubumba umjovo wensimbi

Ubuchwepheshe obusha obusanda kuthuthukiswa bomhlatshelo bomhlatshelo wensimbi yokubumba umjovo we-powder busebenzisa isikhunta se-resin esishumekwe ekubunjweni kwensimbi ukwenza umzimba obalulekile nomzimba wokugcina obunjiwe owenziwe ukubumba komjovo we-metal powder, futhi ekugcineni uncishiswe futhi ucwiliswe. Futhi ukususa. Lobu buchwepheshe bungavimbela kahle umonakalo emzimbeni obunjiwe futhi kulula ukuphatha.

Uma kuqhathaniswa nezinto ezimbotshana ezisekelwe ku-polymer, umkhiqizi wokubumba umjovo wensimbi onezimbotshana zensimbi unokumelana nokushisa okungcono kanye nezakhiwo zemishini. Uma kuqhathaniswa nezinto ze-ceramic, azinayo nje i-ductility engcono, kodwa futhi zine-conductivity ephakeme kagesi kanye ne-thermal. Kulindeleke ukuthi isetshenziswe kabanzi kuzihlungi ezahlukahlukene, ama-Chemical reaction catalysts, ama-heat exchangers, ama-absorber amandla omthelela, njll.

I-MIM (I-Metal Injection Molding) isetshenziswa kunhlobonhlobo yezinto zensimbi ezihlanganisa insimbi ephansi ye-alloy, insimbi engagqwali, insimbi yamathuluzi, ama-alloys asekelwe ku-nickel, ingxubevange ye-tungsten, i-carbide, i-titanium, izinto ezisetshenziswa kazibuthe, ingxubevange ye-Kovar nezitsha zobumba ezinhle, njll.Siyakwamukela nombuzo!
