Metal Injection Molding (MIM) imhando nyowani yePowder metallurgy tekinoroji, iyo inogadzirwa kubva paupfu jekiseni molding (PIM) yezvikamu zveceramic. Matanho makuru ekugadzirwa kweMetal Injection Molding ndeaya anotevera: kusanganiswa kwesimbi poda uye binder-granulation-injection molding-degreasing-sintering-inotevera kurapwa-yekupedzisira chigadzirwa, tekinoroji yakakodzera kune diki, yakaoma, yakakwirira-inoshanda misa kugadzirwa Powder metallurgy. zvikamu, zvakaita seizvo zvinoshandiswa neSwiss watch industry kugadzira zvikamu zvewachi. Mumakumi emakore achangopfuura, tekinoroji yeMIM yakasimukira nekukurumidza, zvinhu zvinoshanda zvinosanganisira: Fe-Ni alloy, simbi isina tsvina, simbi yemidziyo, yakakwirira chaiyo giravhiti alloy, simende carbide, titanium alloy, ni-based superalloy, intermetallic compound, alumina, zirconia nezvimwe zvakadaro. on. Metal Injection Molding (MIM) tekinoroji inoda kuti saizi yehupfu ishoma pane micron uye chimiro chinenge chakatenderera. Pamusoro pezvo, loose density, vibrating density, reshiyo yehurefu kusvika dhayamita, natural slope angle uye particle size distribution inodiwawo. Parizvino, nzira huru dzekugadzira hupfu yesimbi jekiseni rekugadzira tekinoroji ndeyemvura atomization, gasi atomization uye carbonyl boka nzira. Mabhureki eupfu anowanzo shandiswa jekiseni resimbi isina tsvina ndeaya: 304L, 316L, 317L, 410L, 430L, 434L, 440A, 440C, 17-4PH, nezvimwewo. Maitiro emvura atomization ndeaya anotevera: kusarudzwa kwesimbi isina tsvina-yakanyungudika mukati-frequency induction furnace-composition gadziriso-deoxidation uye slag kubviswa-atomization uye pulverization-mhando yekuona-kuongorora-kurongedza uye kuchengetedza, iyo huru midziyo inoshandiswa ndeiyi: medium-frequency induction furnace, high-pressure water pump, yakavharwa pulverizing device, inotenderera tangi remvura, kuongorora uye kurongedza midziyo, yekuedza michina.

Nzira yegasi atomizationzviri sezvinotevera:

kusarudza Stainless simbi mbishi zvinhu-kunyunguduka mukati-frequency induction furnace-composition kugadzirisa-deoxidation uye slag kubviswa-atomization uye pulverization-quality yekucherechedza-kuongorora-kuputira uye kuchengetedza. Midziyo mikuru inoshandiswa ndeiyi: yepakati frequency induction induction yekunyungudutsa, nitrogen sosi uye atomization mudziyo, inotenderera tangi remvura, yekuongorora uye yekurongedza midziyo, yekuyedza michina. Imwe neimwe nzira ine zvayakanakira nezvayakaipira: Mvura Atomization ndiyo huru pulverizing maitiro, kushanda kwayo kwepamusoro, kugadzirwa kwakakura kunowedzera hupfumi, kunogona kuita hupfu hwakatsetseka, asi chimiro hachina kurongeka, chinoita kuti chimiro chekuchengetedza, asi iyo binder rinoshandiswa zvakanyanya, kukanganisa kurongeka. Mukuwedzera, iyo oxidation firimu inoumbwa nekuita kwemvura uye simbi pakupisa kwakanyanya kunotadzisa sintering. Gasi Atomization ndiyo nzira huru yekugadzira hupfu hwesimbi jekiseni rekugadzira tekinoroji. Hupfu inogadzirwa negasi atomization ine spherical, ine yakaderera oxidation dhigirii, shoma binder inodiwa uye yakanaka kuumbwa, asi goho re Ultra-yakatsetseka poda yakaderera, mutengo wakakwira uye chimiro chekuchengetedza chimiro chakashata, c, N, H, O in binder ine simba pane sintered body. Iyo poda inogadzirwa necarbonyl nzira yakakwira mukuchena, yakagadzikana pakutanga uye yakanaka kwazvo muhukuru hwechikamu. Iyo inonyanya kukodzera kuMIM, asi chete Fe, Ni uye mamwe mapoda, ayo asingakwanisi kusangana nezvinodiwa zvemarudzi. Kuti asangane nezvinodiwa zvehupfu hwekuumbwa kwesimbi jekiseni, makambani mazhinji akavandudza nzira dziri pamusoro uye akagadzira micro-atomization uye laminar atomization nzira. Iye zvino inowanzova mvura atomized poda uye gasi atomized poda yakavhenganiswa kushandiswa, yekare yekuvandudza density ye compaction, iyo yekupedzisira kuchengetedza chimiro. Parizvino, kushandisa mvura atomizing poda inogonawo kuburitsa sintered body ine hama density inopfuura 99% , saka mvura chete atomizing poda inoshandiswa kune zvikamu zvakakura, uye gasi atomizing poda inoshandiswa kune zvikamu zvidiki. Mumakore maviri apfuura, Handan Rand Atomizing Pulverizing Equipment Co., Ltd. yakagadzira rudzi rutsva rweatomizing pulverizing midziyo, iyo isingagone kuvimbisa kugadzirwa kwakakura kweatomizing yemvura uye ultrafine poda, asi zvakare funga nezve zvakanakira spherical hupfu chimiro.
