Micro metal poda jekiseni rekugadziranzira: MIM simbiupfu jekiseni kuumbaMethod inyanzvi inoshandisa musanganiswa wesimbi yakatsetseka yehupfu neresin kana wakisi (binder) semidziyo yekuumba simbi jekiseni yozobvisa mafuta (inoora binder) nekunyunguduka kugadzira zvigadzirwa zvesimbi. , Inyanzvi yekugadzira inosanganiswa inobatanidza poda metallurgy uye plastiki jekiseni molding. Inogona kushandisa yakatsetseka simbi hupfu kupfuuraupfu metallurgy, saka inogona kukurudzira sintering kuti ibudise yakakwirira-density zvinhu, uye kuita kwechigadzirwa kunovandudzwa zvakanyanya. Inogonawo kugadzira zvidimbu zvidiki zvesimbi zvine maumbirwo akaomarara uye nemazvo epamusoro. Munguva pfupi yapfuura, iyo micro simbi poda jekiseni rekugadzira nzira yakagadziridzwazve kubudirira.
TheMIM mugadziriine zvinotevera zvishanu zvakanakira:
- Finer metal poda uye binder inosarudzwa kuti iite zvikamu, uye iyo mbishi ine yakanyanya fluidity.
- Iyo homogenization yeyakasvibira zvinhu blanks inowanikwa nekusanganisa uye granulating.
- Iko kushandiswa kweiyo microporous simbi mold yekugadzira tekinoroji yakavandudza kuzadza zvinhu, kuumbwa kugadzikana, kuburitsa mold uye kutakura zvivakwa.
- Iyo yekupisa yekumhanyisa inowedzerwa panguva ye debinding uye sintering process, iyo inogona kudzora kukura kwekristaro tsanga uye kudzivirira deformation uye kukuvara panguva ye shrinkage.
- Precise evaluation tekinoroji yakasimbiswa muchirongwa chekuongorora.
Metal injection molding process
Iyo ichangobva kugadzirwa diki yekupira resin mold yekuwedzera simbi poda jekiseni rekugadzira tekinoroji inoshandisa resin mold yakamisikidzwa musimbi mold kuti iite muviri wakabatana nemuviri wekupedzisira wakaumbwa wakagadzirwa nesimbi poda jekiseni rekuumbwa, uye pakupedzisira inodhirowa uye sintering. Uye kubvisa. Iyi tekinoroji inogona kudzivirira kukuvadzwa kwemuviri wakaumbwa uye iri nyore kubata.
Kuenzaniswa neiyo polymer-yakavakirwa porous zvinhu, iyo porous simbi zvinhu simbi jekiseni yekuumba inogadzira ine nani kupisa kupisa uye michina zvimiro. Kuenzaniswa neceramic zvinhu, ivo havana chete zviri nani ductility, asiwo vane yakakwirira magetsi uye thermal conductivity. Inotarisirwa kushandiswa zvakanyanya mumasefa akasiyana siyana, Chemical reaction catalysts, heat exchangers, inokanganisa simba rinotora, nezvimwe.
MIM (Metal Injection Molding) inoshandiswa kune dzakasiyana siyana dzesimbi zvinosanganisira yakaderera alloy simbi, Stainless simbi, chishandiso simbi, nickel-based alloys, tungsten alloy, carbide, titanium, magineti zvinhu, Kovar alloy uye yakanaka ceramics, nezvimwe.Welcome kubvunza!
