Metal Injection Molding (MIM) imhando itsva yePowder metallurgy tekinoroji, iyo yakagadzirwa kubva kupowder injection molding (PIM) yezvikamu zveceramic. Matanho makuru ekugadzira Metal Injection Molding ndeaya anotevera: kusanganisa simbi powder uye binder-granulation-injection molding-degreasing-sintering-subsequent treatment-final product, tekinoroji iyi yakakodzera kugadzirwa kwesimbi diki, dzakaoma, dzinoshanda zvakanyanya. Zvikamu zvesimbi zvePowder metallurgy, zvakaita sezviya zvinoshandiswa neindasitiri yewachi yeSwiss kugadzira zvikamu zvewachi. Mumakumi emakore achangopfuura, tekinoroji yeMIM yakawedzera nekukurumidza, zvinhu zvinoshanda zvinosanganisira: Fe-Ni alloy, simbi isina ngura, simbi yekushandisa, high specific gravity alloy, cemented carbide, titanium alloy, ni-based superalloy, intermetallic compound, alumina, zirconia nezvimwewo. Tekinoroji yeMetal Injection Molding (MIM) inoda kuti saizi yesimbi yehupfu ive shoma pane micron uye chimiro chayo chiite sedenderedzwa. Pamusoro pezvo, kuzara kwakasununguka, kusimba kwesimba, chiyero chekureba nedhayamita, natural slope angle uye kugoverwa kwehukuru hwezvimedu zvinodiwawo. Parizvino, nzira huru dzekugadzira hupfu hwekugadzira tekinoroji yesimbi injection molding ndedzemvura atomization, gas atomization uye carbonyl group method. Mhando dzehupfu dzinoshandiswa zvakanyanya pakubaya simbi dzisina ngura ndeidzi: 304L, 316L, 317L, 410L, 430L, 434L, 440A, 440C, 17-4PH, nezvimwewo. Maitiro ekugadzira mvura atomization ndeekuti: kusarudzwa kwezvinhu zvisina ngura zvesimbi isina ngura - kunyunguduka mu medium frequency induction furnace - kugadziriswa kwecomposition - deoxidation uye slag removal - atomization uye pulverization - kuonekwa kwemhando yepamusoro - kuongorora - kurongedza nekuchengetedza, michina mikuru inoshandiswa ndeiyi: medium-frequency induction furnace, high-pressure water pombi, closed pulverizing device, circulating water tank, screening and packaging device, testing device.

Maitiro eatomization yegesindeinotevera:

kusarudza simbi isina ngura-kunyunguduka muvira repakati-kugadziriswa kwechimiro-kubviswa kweokisijeni netsvina-kugadziriswa kweatomization ne pulverization-kuongorora kunaka-kurongedza nekuchengetedza. Midziyo mikuru inoshandiswa ndeiyi: vira rekunyungudutsa repakati-frequency, mudziyo wenitrogen source neatomization, tangi remvura rinotenderera, michina yekuongorora nekurongedza, michina yekuedza. Nzira yega yega ine zvayakanakira nezvayakaipira: Water Atomization ndiyo nzira huru yekupwanya, kushanda kwayo kwakanyanya, kugadzirwa kukuru kunodhura mari, kunogona kuita kuti hupfu huve hwakanaka, asi chimiro hachina kurongeka, izvo zvinobatsira kuchengetedza chimiro, asi binder inoshandiswa zvakanyanya, inokanganisa kururama. Pamusoro pezvo, firimu re oxidation rinoumbwa nekuita kwemvura nesimbi pakupisa kwakanyanya kunodzivirira kupisa. Gas Atomization ndiyo nzira huru yekugadzira hupfu hwetekinoroji yekuumba simbi. Hupfu hunogadzirwa negasi hunoita sedenderedzwa, hune mwero weoxidation yakaderera, hunodiwa zvishoma uye hunogona kugadzirwa zvakanaka, asi goho rehupfu hwakatsetseka hwakaderera, mutengo wakakwira uye hunhu hwekuchengetedza chimiro hwakaderera, c, N, H, O mu binder hune simba pamuviri wakacheneswa. Hupfu hunogadzirwa ne carbonyl method hwakanyanya kuchena, hwakagadzikana pakutanga uye hwakatsetseka muhukuru hwezvimedu. Hunonyanya kukodzera MIM, asi chete kune Fe, Ni nedzimwe hupfu, dzisingakwanise kusangana nezvinodiwa zvemarudzi akasiyana-siyana. Kuti zvizadzise zvinodiwa zvehupfu hwesimbi yekuumba, makambani mazhinji akavandudza nzira dziri pamusoro apa uye akagadzira nzira dze micro-atomization uye laminar atomization. Iye zvino kazhinji hupfu hwakasanganiswa hwemvura negasi hunoshandiswa zvakasanganiswa, hwekutanga kuvandudza huwandu hwekusimba, hwekupedzisira kuchengetedza chimiro. Parizvino, kushandisa hupfu hwemvura hunogonawo kugadzira muviri wakacheneswa une huwandu hunopfuura 99%, saka hupfu hwemvura hunoshandiswa chete kune zvikamu zvikuru, uye hupfu hwegasi hunoshandiswa kune zvikamu zvidiki. Mumakore maviri apfuura, Handan Rand Atomizing Pulverizing Equipment Co., Ltd. yakagadzira mhando itsva yemidziyo yekupwanya atomizing, iyo isingangogone chete kuve nechokwadi chekugadzirwa kukuru kweatomizing yemvura neupfu hwakatsetseka, asiwo inofunga nezvezvakanakira chimiro cheupfu hwakatenderera.
