Ndezvipi zvishongedzo zvakafanira simbi poda jekiseni molding tekinoroji?

1.Chii chinonzi metal powder injection molding teknolojia?

 

Munyika yeupfu metallurgy,Metal powder injection molding (MIM) imhando yepedyo net molding tekinoroji. Matanho matanhatu anoumba iyo MIM maitiro: kugadzira hupfu, kuisanganisa nebhainda, jekiseni kuumba, kuwedzera degreasing uye debinding agent, sintering uye kurapa, uye kupedza.

 

Iwo mameseji ndeaya anotevera: Kugadzirwa kweMIM kunoda diki simbi poda particle size, kazhinji muhuwandu hwe0 kusvika 30 microns, ne-ultra-high pressure water atomization nzira kana gasi atomization nzira; Yakasanganiswa poda uye binder: iyo simbi poda uye organic binder zvakasanganiswa zvizere muzvidimbu, uye musanganiswa zvidimbu zvinopisa mupurasitiki; Injection molding: kuburikidza nemushini wekuumba jekiseni kusvina musanganiswa mugomba rekuumbwa, kugadzira zvikamu zvekutanga kushaikwa; Degreasing binder: nemakemikari kana thermal decomposition nzira yekubvisa binder muzvikamu billet, kuwana simbi chete kana zvishoma binder residual parts billet; Sintering and cure: the parts is sent to the sintering furnace for kurapa kuti uwedzere kubvisa binder yakasara; Mushure mekurapa: kuburikidza nekudzima kupisa kwekupisa, makemikari kupisa kurapwa, kurapa kweutsi uye dzimwe nzira dzekudzikisa mukati ma pores ezvikamu, kuvandudza density yezvikamu, kuvandudza kusimba kwezvikamu, kushorwa kwekupokana uye kusagadzika kwekupfeka, nezvimwewo, kugadzira zvikamu zvekupedzisira.

 

2, Ndezvipi zvishongedzo zvakafanira simbi poda jekiseni molding tekinoroji?

 

China MIM parizvino inoshandiswa zvakanyanya muzvigadzirwa zvakasiyana siyana, zvinosanganisira wachi, midziyo midiki yekurapa, midziyo yemitambo, mwenje wezvombo, nezvimwe zvinhu. Tekinoroji yeMIM, inova imwe yehunyanzvi hwekuwedzera tekinoroji kune echinyakare machining, inogona kushandisa zvigadzirwa uye kugadzira zvigadzirwa zvine akaomarara zvimiro zvakanyanya kupfuura zvechinyakare machining.

 

Iko kugadzirisa kunoshanda kuMIM tekinoroji inogona kuiswa mune anotevera mamiriro:

 

1, mune yechinyakare yekucheka kana kugaya, kurasikirwa kwezvinhu kwakakura kwazvo, uye nguva yekugadzira ikati yakareba zvikamu, inokodzera tekinoroji yeMIM kuderedza mutengo.

 

2, MIM inogona kuve kugadzirwa kwakawanda, kusangana nemamwe mamiriro ekugadzirwa kwehuwandu, asi kudiwa kwakaderera pane mutengo wekuvhura mold zvikamu zvakakodzera tekinoroji yeMIM.

 

3. Kune simbi dzakaoma kucheka, dzakadai setitanium uye nickel alloy, teknolojia yeMIM inogona kuonekwa pakugadzira. Iko kurongeka kwezvigadzirwa kuchavandudzwa kana zvichienzaniswa nekugadzirwa kwechinyakare, uye zvinhu zvichachengetwa zvakanyanya.

 

4, iine chimiro chakaoma chejometri, senge shinda yepasi, klooping, cross passage uye zvimwe zvikamu, zvikamu zvakadaro mune zvechinyakare simbi metallurgy zvakaoma kuwana, mukucheka maitiro kunoda kushandura chiteshi chekugadzira cheakawanda-axis zvikamu kana akawanda-reference parts, akakodzera MIM tekinoroji kugadzirisa.

 

5. Zvikamu zvinoda kugadziriswa nekubatanidzwa kwezvinhu zvakasiyana-siyana, zvakadai sezvikamu zvakagadziriswa nekubatanidzwa kwesimbi uye ceramic zvinhu, kana zvikamu zvakasimbiswa nezvinhu zvakasiyana-siyana, zvakadai semagineti akaoma - akanyorova magnetic, magnetic - non-magnetic, conductive - insulating materials.

 

3, Ndezvipi zvinhu zvakakodzera simbi poda jekiseni kuumba tekinoroji?

 

Tekinoroji yeMIM inoshanda kune zvakati wandei zvinhu. Muchidimbu, chero nguva yekunyungudika iri pamusoro pekupisa kwekupisa, zvinhu zvehupfu zvinogona kuitwa zvikamu neMIM tekinoroji. Tichifunga nezvehupfumi, zvinhu zvinowanzo shandiswa zvino zvinosanganisira iron base, nickel base, low alloy, hard alloy, etc. JIEHUANG CHIYANG asMugadziri wezvikamu zveMIMinopa ferrous uye nickel-based alloy simbi poda zvinhu zvesimbi poda jekiseni kuumba, ine zvinhu zvinoratidzira zvinosvika padanho repamusoro reindasitiri.
