MIM txheej txheem ntws thiab qhov zoo ntawm Hlau Txhaj Moulding
1, cov ntsiab lus Hlau txhaj tshuaj molding (MIM) yog cov khoom lag luam sib txawv, sib koom ua ke ob txoj kev sib txawv ua tiav (yas txhaj tshuaj molding thiab hmoov metallurgy). Nws ua rau cov neeg tsim qauv tshem tawm cov kev txwv ib txwm muaj thiab tau txais tus nqi qis, tshwj xeeb zoo li stainless hlau, npib tsib xee, hlau, tooj liab, titanium thiab lwm yam hlau los ntawm yas molding, yog li muaj kev ywj pheej tsim ntau dua li ntau lwm cov txheej txheem ntau lawm. |  |
2, Kev ntsuam xyuas ua ntej muag Pab pawg muag khoom ntawm Zhongwei Precision yuav ua haujlwm ze nrog koj los txiav txim siab seb cov khoom lag luam yuav tsum ua haujlwm puas tsim nyog rau MIM txheej txheem kev tsim khoom raws li tus nqi, cov khoom siv thiab kev tsim khoom. Nyob rau tib lub sijhawm, engineers tseem yuav muab cov lus qhia los hloov cov qauv tsim kom ua tiav cov txiaj ntsig zoo los ntawm MIM |  |
3, Cov khoom siv raw Cov hmoov hlau tshwj xeeb (qib micron) yog tov nrog cov khoom zoo polymer los tsim ib qho tshwj xeeb pub rau MIM los ntawm cov txheej txheem kev npaj ua ntej. Piv nrog rau cov hmoov hlau metallurgy, qhov loj me me ntawm cov hmoov hlau (micron qib) thiab cov ntsiab lus tsis tshua muaj impurity kom ntseeg tau tias qhov ntom ntom ntawm MIM ncav cuag 98 feem pua ntawm cov theoretical ntom; Ntau yam tshwj xeeb npaj cov polymers tuaj yeem tsis tsuas yog muab cov dej ntws zoo thaum txhaj tshuaj, tab sis kuj ua kom muaj peev xwm degreasing zoo. |  |
4, Txhaj tshuaj MIM pub yog rhuab thiab sib npaug rau hauv pwm kab noj hniav los ntawm lub tshuab txhaj tshuaj, thiab MIM txhaj tshuaj dawb yog tau tom qab txias. Tus yuam sij rau cov txheej txheem no yog kom phim cov pwm uas ua raws li cov yam ntxwv ntawm MIM nrog cov txheej txheem tsim nyog |  |
5, Degrease Cov kws tshaj lij degreasing rauv yog siv los maj mam tshem tawm cov ntaub ntawv tseem ceeb hauv kev txhaj tshuaj dawb paug, thiab cov pob txha pob txha ruaj khov tuav cov khoom zoo kom cov khoom degreased tuaj yeem txav mus rau theem kub. |  |
6,Degreasing sintering Nyob rau hauv lub tshuab nqus tsev vacuum los yog cua sov cua sov ntawm MIM, lub cev pob txha binder raug tshem tawm, thiab cov hmoov hlau yog densified mus rau hauv ib tug tiav hlau lub cev ntawm qhov kub thiab txias ze rau lub melting point. Tom qab txias, cov sintered qhov chaw nrog ib tug zoo li ze rau cov khoom tiav lawm. |  |
MIM ib feem txheej txheem kom zoo dua 1: siab heev ntawm kev tsim kev ywj pheej Piv nrog rau lwm txoj kev tsim hlau, MIM tuaj yeem tsim cov khoom nrog cov duab ntau dua. Yeej, txhua yam qauv uas tuaj yeem paub tau los ntawm kev txhaj tshuaj pwm tuaj yeem siv rau MIM | MIM txheej txheem kom zoo dua 2: ntau yam khoom xaiv |
MIM txheej txheem kom zoo dua 3: zoo heev lub cev thiab tshuaj Vim tias qhov sintering ceev ntawm MIM yog ze rau qhov theoretical ntom ntom, nws lub cev thiab cov khoom siv tshuaj lom neeg kuj zoo heev, xws li cov neeg kho tshuab lub zog, uas zoo heev tshaj cov tsoos hmoov metallurgy. . | MIM txheej txheem kom zoo dua 4: exquisite tsos Qhov saum npoo roughness (Ra) ntawm MIM sintered billet tuaj yeem ncav cuag 1 μm. Nws tseem tuaj yeem tau txais cov txiaj ntsig zoo nkauj los ntawm ntau txoj kev kho saum npoo. |
MIM txheej txheem kom zoo dua 5: siab dua qhov tseeb Feem ntau, qhov kam rau ua qhov tseeb ntawm ± 0.5 feem pua tuaj yeem ua tiav nrog MIM, thiab qhov siab dua qhov tseeb tuaj yeem ua tiav nrog lwm txoj kev ua haujlwm. | MIM txheej txheem kom zoo dua 6: muaj zog thiab yoog raws huab hwm coj ntau lawm MIM tuaj yeem hloov kho tau yooj yim thiab ua kom cov zis ntau ntxiv, los ntawm ntau pua daim ib hnub mus rau ntau pua txhiab daim ib hnub. |
MIM txheej txheem kom zoo dua 7: ib puag ncig-phooj ywg ua lub tswv yim Kev siv tus nqi ntawm cov ntaub ntawv raw yog ze rau 100 feem pua, uas yog ib qho ze ze ntawm kev tsim tshuab thiab tuaj yeem zam cov khoom pov tseg. |
