Hlau txhaj molding MIM txheej txheem

1. Dab tsi yoghlau txhaj molding?

Hlau Txhaj Moulding (MIM)yog ib tug tshiab ze-net tsim technology nyob rau hauv lub teb ntawmhmoov metallurgy. Cov txheej txheem MIM suav nrog rau 6 kauj ruam:Hlau hmoov Binder-Kneading-Txhaj Molding-Debinding-intering thiab solidification-tom qab ua tiav.

Hmoov:Covhmoov hlauyuav tsum tau rau MIM muaj ib tug me me particle loj, feem ntau nyob rau hauv thaj tsam ntawm 0 mus rau 30 microns, thiab yog tsim los ntawm ib tug heev high-pressure dej atomization txoj kev los yog ib tug gas atomization txoj kev;

Mixed hmoov thiab binder:hlau hmoov thiab organic binder yog tag nrho tov los ua cov khoom, thiab cov khoom sib tov yog rhuab mus rau lub xeev plasticized;

Txhaj tshuaj molding: Qhov sib tov yog extruded rau hauv pwm kab noj hniav los ntawm kev txhaj tshuaj molding tshuab los ua ib feem ntxhib;

Degreasing thiab khi tus neeg sawv cev tshem tawm:Lub binder nyob rau hauv ib feem dawb paug yog muab tshem tawm los ntawm cov tshuaj los yog thermal decomposition kom tau ib feem dawb paug nrog tsuas yog hlau los yog tsuas yog ib tug me me ntawm cov binder tshuav;

Sintering thiab curing:Xa cov khoom mus rau hauv lub qhov cub sintering rau solidification kom tshem tawm cov residual binder ntxiv;

Post-processing:Siv quenching tshav kub kev kho mob, tshuaj tua hluav taws kub, kev kho cua sov thiab lwm txoj kev los txo cov pores sab hauv ntawm ib feem, txhim kho qhov ntom ntawm ib feem, txhim kho lub zog ntawm ib feem, corrosion kuj thiab hnav tsis kam, thiab lwm yam, los tsim qhov kawg.

2. Nyob rau hauv cov xwm txheej twg yog hlau txhaj molding haum?

Tam sim no,MIM txheej txheem yog dav siv nyob rau hauv cov khoom siv hluav taws xob, watches, khoom siv kho mob me me, tsheb cav qhov chaw, cov khoom ua si, riam phom, thiab lwm yam.Piv nrog rau kev siv tshuab ua haujlwm ib txwm muaj, MIM thev naus laus zis tuaj yeem siv cov ntaub ntawv zoo thiab tsim cov khoom nrog cov qauv nyuaj. Nws yog ib txoj hauv kev zoo ntxiv rau kev ua ib txwm ua.

Cov txheej txheem siv tau rau MIM thev naus laus zis tuaj yeem faib ua cov xwm txheej hauv qab no:

1. 1. Hauv cov txheej txheem txiav los yog sib tsoo, cov khoom poob yog qhov loj heev, thiab cov khoom siv nrog lub sijhawm ua haujlwm ntev yog tsim nyog rau kev txo nqi los ntawm MIM technology.

1. 2. MIM tuaj yeem ua tau loj. Cov khoom uas ua tau raws li qee qhov kev tsim khoom loj tab sis muaj qhov xav tau qis ntsig txog pwm qhib cov nqi tsim nyog rau MIM thev naus laus zis.

1. 3. Cov hlau uas nyuaj rau kev txiav, xws li titanium, nickel alloys, thiab lwm yam, tuaj yeem tsim los ntawm MIM technology. Qhov tseeb ntawm cov khoom yuav raug txhim kho piv nrog kev ua ib txwm ua, thiab cov ntaub ntawv yuav tau txais txiaj ntsig zoo.

1. 4. Qhov chaw nrog cov geometries nyuaj, xws li qhov chaw nrog cov xov nto, knurling, hla txoj kab, thiab lwm yam. Cov khoom no nyuaj rau kev ua tiav hauv cov hmoov metallurgy. Multi-axis qhov chaw lossis multi-datum qhov chaw uas yuav tsum tau muaj ntau yam kev hloov pauv ntawm cov chaw ua haujlwm thaum txiav. Cov khoom tsim nyog rau kev ua tiav los ntawm MIM thev naus laus zis.

1. 5. Cov khoom uas yuav tsum tau ua tiav los ntawm kev sib xyaw ntawm cov khoom sib txawv, xws li cov khoom ua tiav nrog cov khoom siv hlau thiab cov khoom siv ceramic, los yog cov khoom ua los ntawm cov khoom sib txawv, xws li cov khoom sib nqus-soft magnetic, sib nqus-tsis-magnetic, conductive-insulating cov ntaub ntawv Overlay.

3. Cov ntaub ntawv dab tsi tsim nyog rau kev txhaj tshuaj molding tshuab?

Qhov ntau ntawm cov ntaub ntawv siv rau hlau txhaj tshuaj molding yog qhov dav. Raws li txoj cai, cov khoom tuaj yeem tsim los ntawm MIM tsuav yog tias cov khoom siv hmoov muaj qhov melting point saum qhov kub ntawm sintering. Xav txog kev lag luam, tam sim no cov khoom siv feem ntau suav nroghlau-raws li, npib tsib xee-based, thiab tsis tshua muaj alloys. Carbide, Titanium alloy, ceramic thiab lwm yam.
