Qhov tseem ceeb ntawm kev tswj qhov kub thiab txias hauv MIM

Raws li peb paub, kev tswj qhov kub thiab txias yog qhov tsim nyog rau txhua qhov kev ua haujlwm thermal, cov ntaub ntawv sib txawv yuav tsum muaj kev kho mob sib txawv, thiab txawm tias tib cov ntaub ntawv nrog qhov sib txawv ntom ntom, kuj xav tau kev hloov kho qhov kub thiab txias.Kub tsis yog tsuas yog tus yuam sij tseem ceeb rau cov txheej txheem thermal, nws tseem ceeb tshwj xeeb tshaj yog rau MIM kev lag luam vim nws ncaj qha cuam tshuam rau kev ua tau zoo kawg ntawm cov khoom txawm tias phim qhov yuav tsum tau ua lossis tsis.Yog li yuav ua li cas kom paub tseeb tias qhov kub thiab txias tuaj yeem tswj tau zoo thaum lub sijhawm tsim khoom, uas yog cov lus nug, KELU xav txog kev sib tham los ntawm ob yam.

Ua ntej ntawm tag nrho cov, nws yog lub uniformity nyob rau hauv lub cub tawg thaum sintering, nws yog ib qho tseem ceeb heev rau cov hlau txhaj tshuaj molding (MIM).Cov khoom lag luam zoo hauv cov txheej txheem no, nyob ntawm cov khoom ua tiav pom qhov kub thiab txias tsis hais txog lawv txoj haujlwm hauv qhov cub.Raws li lub cub tawg loj dua, nws nyuaj rau paub thiab txhais qhov chaw qab zib hauv lub cub tawg vim tias thaum lub thermocouple nyeem qhov ntsuas kub, nws tsis txhais tau tias tag nrho lub cub tawg yog qhov kub ntawm qhov ntawd.Qhov no yog tshwj xeeb tshaj yog muaj tseeb rau ib tug loj batch furnace cua sov nrog ib tug tag nrho load thaum muaj ib tug loj kub gradient ntawm sab nraud ntawm lub load thiab qhov chaw ntawm lub load.

Cov binders hauv MIM tivthaiv raug tshem tawm los ntawm kev tuav ntawm qhov kub thiab txias rau ib lub sijhawm.Yog tias qhov kub thiab txias tsis ua tiav nyob rau hauv tag nrho cov load, qhov profile tuaj yeem txav mus rau ntu tom ntej, uas feem ntau yog ib qho ramp.Binders yuav evolved tawm ntawm ib feem thaum lub sij hawm ramp no.Nyob ntawm tus nqi ntawm cov binder tshuav nyob rau hauv ib feem thiab qhov kub thiab txias thaum lub sij hawm ramp, lub evaporation ntawm lub binder tam sim ntawd yuav ua rau cov kab nrib pleb los yog hlwv tsis tuaj yeem.Qee qhov xwm txheej, kev tsim cov kua qaub tshwm sim, uas yuav ua rau cov khoom sib xyaw ntawm cov khoom hloov pauv.

Ntxiv mus, peb tuaj yeem tswj qhov kub thiab txias nrog Nozzle thiab chim los ntawm kev txhaj tshuaj molding txheej txheem.Nozzle kub feem ntau yog me ntsis qis dua qhov siab tshaj plaws ntawm lub thoob, uas yog los tiv thaiv qhov tshwm sim salivation uas yuav tshwm sim nyob rau hauv lub nozzle.Qhov kub ntawm lub nozzle yuav tsum tsis txhob qis dhau, txwv tsis pub lub nozzle yuav raug thaiv vim yog yaj thaum ntxov solidification.Nws tseem yuav cuam tshuam cov khoom ua haujlwm.Barrel kub.Qhov kub ntawm lub thoob, lub nozzle thiab pwm yuav tsum tau tswj thaum txhaj tshuaj molding.Thawj ob qhov kub thiab txias feem ntau cuam tshuam rau cov hlau plasticization thiab kev ua haujlwm, thiab qhov kawg yog feem ntau cuam tshuam rau kev ua haujlwm hlau thiab cua txias.Txhua lub hlau muaj qhov sib txawv ntawm qhov kub thiab txias.Txawm tias tib cov hlau muaj qhov sib txawv ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob vim muaj cov keeb kwm sib txawv lossis hom.Qhov ntawd yog vim qhov sib txawv nruab nrab molecular hnyav faib.Cov txheej txheem hlau plasticizing nyob rau hauv cov tshuab txhaj tshuaj sib txawv kuj sib txawv, kom lub thoob kub sib txawv.

Nws tsis muaj teeb meem dab tsi ntawm kev tsis saib xyuas nyob rau hauv uas cov txheej txheem me me, qhov ua tsis tiav yog kev zam.Luckily KELU engineer team muaj kev paub zoo thiab cov txheej txheem ntau tshaj li kaum xyoo, ua rau peb cov neeg siv khoom tsis muaj kev txhawj xeeb txog cov khoom zoo.Zoo siab txais tos los tham nrog peb pab neeg yog tias muaj lus nug lossis kev cai tsim, peb pab neeg yuav pab kom paub koj tus npau suav.
