Txhaj tshuaj molding yog cov txheej txheem tsim khoom nrov siv hauv kev tsim khoom ntawm ntau yam khoom thiab cov khoom. Nws suav nrog kev siv cov pwm, cov khoom siv cua sov, thiab lub zog los tsim ntau yam duab thiab tsim. Cov txheej txheem feem ntau yog siv los tsim cov khoom yas, tab sis nws kuj tuaj yeem siv nrog lwm cov ntaub ntawv xws li hlau. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov hlau uas tuaj yeem txhaj tshuaj molded, lawv cov khoom, thiab qee qhov zoo thiab qhov tsis zoo ntawm kev siv hlau txhaj tshuaj molding (MIM) dua lwm txoj kev.
Hlau Txhaj Moulding (MIM) yog dab tsi?
Hlau txhaj tshuaj molding yog txheej txheem tsim khoom uas koom nrog kev tsim cov hlau los ntawm kev txhaj tshuaj molding. Nyob rau hauv cov txheej txheem no, hlau hmoov yog tov nrog ib tug binder khoom los tsim ib tug feedstock. Tom qab ntawd cov khoom noj khoom haus tau muab tso rau hauv lub tshuab txhaj tshuaj molding, qhov twg nws tau rhaub kom kub thiab txhaj rau hauv pwm. Cov hlau yog ces solidified thiab ib feem yog ejected los ntawm pwm.
MIM feem ntau yog siv rau hauv kev tsim cov khoom me me, cov hlau tsis yooj yim uas yuav tsum tau muaj qhov tseeb thiab qhov tseeb. Nws yog ib txoj hauv kev zoo tshaj plaws rau kev tsim cov khoom nrog cov duab sib txawv thiab cov ntsiab lus xws li lub zog, bearings, thiab lwm yam khoom siv tshuab.
Cov hlau twg tuaj yeem txhaj Moulded?
MIM tuaj yeem siv nrog ntau yam hlau, nrog rau cov hlau tsis muaj steel, titanium, tungsten, cobalt-chrome, thiab lwm yam. Cov hlau feem ntau siv hauv MIM yog stainless hlau vim nws cov khoom siv zoo heev, kev tiv thaiv corrosion, thiab kev ua haujlwm yooj yim. Lwm cov hlau uas feem ntau siv hauv MIM suav nrog nickel alloys, tooj liab alloys, thiab titanium alloys.
Kev xaiv cov hlau rau MIM yog nyob ntawm ntau yam, suav nrog cov khoom siv kho tshuab uas xav tau, kev tiv thaiv corrosion, thiab qhov kawg daim ntawv thov ntawm cov khoom. Txhua cov hlau muaj nws cov khoom tshwj xeeb thiab cov yam ntxwv, ua rau nws haum rau kev siv sib txawv.
Stainless hlau
Stainless hlau yog cov hlau feem ntau siv hauv MIM. Nws yog ib qho alloy ntawm hlau, chromium, thiab nickel thiab paub txog nws lub zog siab, corrosion kuj, thiab kav ntev. Muaj ntau ntau qib sib txawv ntawm stainless hlau, txhua tus muaj nws tus kheej cov khoom thiab cov yam ntxwv.
Ib qho ntawm feem ntau siv qib stainless hlau hauv MIM yog 17-4 PH. Cov qib no muaj lub zog siab, zoo corrosion kuj, thiab muaj peev xwm los kho cua sov kom muaj zog ntxiv. Lwm cov qib stainless hlau uas feem ntau siv hauv MIM suav nrog 304, 316, thiab 420.
Titanium
Titanium yog lub teeb yuag, muaj zog thiab corrosion-resistant hlau uas feem ntau siv hauv kev lag luam aerospace thiab kev kho mob. Nws muaj peev xwm tiv taus corrosion thiab tuaj yeem tiv taus qhov kub thiab txias, ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau muaj zog thiab kav ntev.
Ib qho ntawm feem ntau siv titanium alloys hauv MIM yog Ti-6Al-4V. Cov hlau no muaj lub zog siab, zoo heev corrosion kuj, thiab zoo biocompatibility, ua rau nws zoo tagnrho rau kev cog qoob loo thiab lwm yam kev siv.
Cobalt-Chrome
Cobalt-chrome alloys paub txog lawv lub zog siab, hnav tsis kam, thiab zoo biocompatibility. Lawv feem ntau siv hauv kev lag luam kho mob rau cov ntawv thov xws li kev cog hniav orthopedic, kev cog hniav, thiab cov cuab yeej phais.
Ib qho ntawm feem ntau siv cobalt-chrome alloys hauv MIM yog Co-Cr-Mo. Cov hlau no muaj lub zog siab, zoo heev corrosion kuj, thiab biocompatibility, ua rau nws zoo tagnrho rau orthopedic implants thiab lwm yam kev siv kho mob.
Qhov zoo ntawm Hlau Txhaj Moulding
MIM muaj ntau yam zoo dua lwm yam kev tsim khoom xws li casting, forging, thiab machining. Qee qhov zoo ntawm MIM suav nrog:
- High precision thiab dimensional precision
- tuaj yeem tsim cov duab thiab cov qauv tsim
- Cov khoom pov tseg tsawg
- Txo cov kev xav tau tom qab ua tiav
- Txo cov sij hawm txhuas thiab cov nqi tsim khoom
- Txhim kho cov khoom siv kho tshuab
Disadvantages ntawm Hlau Txhaj Molding
Thaum MIM muaj ntau qhov zoo, kuj tseem muaj qee qhov tsis zoo rau cov txheej txheem tsim khoom no. Qee qhov tsis zoo ntawm MIM suav nrog:
- Txwv cov khoom loj thiab qhov nyuaj
- Cov cuab yeej siv siab dua
- Kev xaiv cov ntaub ntawv txwv
- Tsawg tus nqi ntau lawm
Xaus
Kev txhaj tshuaj molding yog txheej txheem tsim khoom siv ntau yam uas tuaj yeem siv nrog ntau yam khoom, suav nrog hlau. Hlau txhaj tshuaj molding (MIM) yog ib hom kev txhaj tshuaj molding siv rau kev tsim cov khoom siv hlau nyuaj. MIM tuaj yeem siv nrog ntau yam hlau, nrog rau cov hlau tsis muaj steel, titanium, cobalt-chrome, thiab lwm yam. Txhua cov hlau muaj nws cov khoom tshwj xeeb thiab cov yam ntxwv, ua rau nws haum rau kev siv sib txawv. Thaum MIM muaj ntau qhov zoo dua lwm cov txheej txheem tsim khoom, kuj tseem muaj qee qhov tsis zoo rau txoj kev no. Zuag qhia tag nrho, MIM yog ib txoj hauv kev zoo tshaj plaws rau kev tsim cov khoom me me, cov hlau nyuaj uas yuav tsum tau muaj qhov tseeb thiab qhov tseeb.
