MIM (Hloov Txhaj Moulding) yog cov ntawv luv ntawm cov hlau txhaj tshuaj molding. Nws yog ib txoj kev molding ntawm txhaj cov yas sib xyaw ntawm cov hmoov hlau thiab nws cov ntawv khi rau hauv cov qauv. Nws yog cov duab uas xav tau los ntawm kev sib xyaw cov hmoov xaiv thiab cov ntawv khi, tom qab ntawd granulating qhov sib tov, thiab tom qab ntawd txhaj tshuaj molding.

2. Hlau Txhaj Moulding (MIM) txheej txheem

Cov txheej txheem MIM muab cov kev hloov pauv ntawm kev txhaj tshuaj molding tsim nrog lub zog siab thiab kev ncaj ncees ntawm cov hlau precision kom ua tiav cov kev daws teeb meem qis rau cov khoom geometric nyuaj heev.

Cov txheej txheem MIM tau muab faib ua plaub theem ua haujlwm tshwj xeeb (sib tov, molding, degreasing thiab sintering) kom paub txog cov khoom tsim, thiab txiav txim siab seb puas yuav tsum tau kho qhov chaw raws li cov khoom yam ntxwv.

Cov txheej txheem tsim khoom ntawm MIM feem ntau suav nrog kev sib xyaw granulation, txhaj tshuaj molding, degreasing, sintering thiab kev kho mob theem nrab.

3. Cov yam ntxwv tseem ceeb ntawm MIM txheej txheem:

Haum rau kev tsim cov khoom siv hmoov ntau, cov khoom siv dav siv;

Kev siv tus nqi siab ntawm cov ntaub ntawv raw, qib siab ntawm kev tsim khoom automation, haum rau kev tsim khoom loj.

Nws tuaj yeem tsim qhov me me nrog cov duab kos duab (0.03g ~ 200g);

Qhov siab qhov tseeb ntawm qhov chaw (± {{0}}}.1 feem pua ​​- ± 0.5 feem pua), zoo nto tiav (roughness 1 - 5 μ m);

Cov khoom lag luam muaj qhov sib txheeb siab ntom ntom (95 ~ 100 feem pua), cov qauv zoo sib xws thiab kev ua haujlwm zoo heev;

4. Cov txheej txheem kho saum npoo feem ntau ntawm MIM qhov chaw

Kev kho polishing

Siv cov khoom siv hluav taws xob, tshuaj lom neeg lossis electrochemical los txo qhov roughness ntawm cov khoom ua haujlwm kom tau txais qhov ci ntsa iab thiab tiaj tus.

Kev kho electroplating

Cov txheej txheem ntawm kev siv electrolysis los txuas ib txheej ntawm cov yeeb yaj kiab hlau rau saum npoo ntawm cov hlau lossis lwm yam ntaub ntawv. Electroplating tuaj yeem tiv thaiv cov hlau oxidation (xws li xeb), txhim kho hnav tsis kam, conductivity, cuam tshuam cov khoom, corrosion kuj (tooj liab sulfate, thiab lwm yam), thiab txhim kho kev zoo nkauj.

Kev kho PVD

Cov txheej txheem ntawm kev hloov cov atoms los yog molecules los ntawm qhov chaw mus rau saum npoo ntawm substrate los ntawm cov txheej txheem ntawm lub cev. Nws txoj haujlwm yog ua kom qee cov khoom siv tshwj xeeb (lub zog siab, hnav tsis kam, kub dissipation, corrosion kuj, thiab lwm yam) txau ntawm lub matrix nrog qis kev ua haujlwm, kom lub matrix muaj kev ua tau zoo dua.

Blackening kev kho mob

Nws yog ib txoj kev kho tshuaj lom neeg los tsim ib txheej ntawm oxide zaj duab xis ntawm cov hlau nto kom cais cov huab cua thiab ua tiav lub hom phiaj ntawm kev tiv thaiv xeb. Thaum cov tsos mob yuav tsum tsis siab, kev kho blackening tuaj yeem raug saws. Cov khoom tseem ceeb ntawm blackening cawv yog sodium hydroxide thiab sodium nitrite.

Kev kho phosphating

Nws yog cov txheej txheem ntawm cov tshuaj lom neeg thiab cov tshuaj electrochemical los tsim cov phosphate zaj duab xis. Lub hom phiaj tseem ceeb ntawm phosphating yog:

1) Muab kev tiv thaiv rau lub hauv paus hlau los tiv thaiv cov hlau los ntawm corrosion mus rau ib qho twg;

2) Nws yog siv rau priming ua ntej painting los txhim kho cov adhesion thiab corrosion kuj ntawm cov xim zaj duab xis.

Txau kev kho mob

Nws yog hais txog cov txheej txheem txheej txheej uas yog siv rau saum npoo ntawm cov khoom yuav tsum tau coated los ntawm rab phom los yog disc atomizer, nrog kev pab los ntawm lub siab los yog centrifugal quab yuam, disperse mus rau hauv uniform thiab zoo tee dej.

Hauv cov ntsiab lus:

1) Polishing thiab phosphating feem ntau yog ua ntej kev kho mob los npaj rau lwm yam kev kho mob tom qab;

2) Electroplating thiab PVD yog ob hom kev kho mob uas tau siv dav;

3) Blackening thiab txau yuav zoo heev hloov qhov chaw ntawm cov khoom, uas yog ntau haum rau loj workpieces.

5. Cov ntaub ntawv siv tau thiab daim ntawv thov teb:

MIM tau siv dav, suav nrog cov khoom siv niaj hnub, xws li tsheb, kev lag luam aerospace, kev lag luam tub rog, xov tooj ntawm tes, watches, khoom siv kho mob, khoom siv hauv tsev, koob yees duab thiab cov cuab yeej hluav taws xob nrog MIM qhov chaw. MIM thev naus laus zis tuaj yeem siv rau txhua yam khoom uas tuaj yeem ua hmoov,

6. Cov ntaub ntawv siv MIM tam sim no feem ntau suav nrog:

Stainless hlau, hlau puag alloy, cov khoom sib nqus, tungsten alloy, nyuaj alloy, zoo ceramics, thiab lwm yam.
