Thaum koj hnov 'silicon pwm casting', lub siab feem ntau dhia ncaj nraim mus rau cov khoom me me los yog cov neeg nyiam ua qauv. Qhov ntawd yog ib qho kev txwv, thiab ncaj ncees txwv, misconception. Nyob rau hauv cov ntsiab lus ntawm kev lag luam, tshwj xeeb tshaj yog thaum koj tab tom soj ntsuam nrog cov geometries nyuaj rau cov hlau ua haujlwm, lub luag haujlwm ntawm silicone-cuam tshuam 'e', cov khoom siv qib-yog deb dua nuanced. Nws tsis yog qhov khoom kawg tab sis qhov tseem ceeb, feem ntau tsis sib tham, cov cuab yeej nruab nrab. Kuv qhov kev paub dhau los ob qho tib si qhov tseeb qhov chaw tsim khoom thiab lub khw machining, thiab kuv tau pom ntau txoj haujlwm ua rau poob siab los ntawm kev kho cov txheej txheem pwm ua qhov kev xav tom qab. Qhov tseeb yog, qhov zoo ntawm koj cov pwm silicone ncaj qha dictates qhov zoo ntawm cov qauv siv quav ciab, uas nyob rau hauv lem txhais cov hlau casting zaum kawg. Tau thawj kauj ruam tsis ncaj ncees lawm, thiab koj tsuas yog machining seem.
Silicone Choj: Los ntawm 3D Model rau Wax Pattern
Wb tham txog txheej txheem. Peb tsis cam khwb cia hlau ncaj qha rau hauv silicone. Qhov ntawd yog ib qho kev sib txawv tseem ceeb. Nyob rau hauv peev casting, uas yog peb lub lag luam tseem ceeb ntawm Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), silicone pwm yog siv tshwj xeeb los tsim cov qauv siv quav ciab. Cov kab ke yog: tus qauv qauv (feem ntau 3D luam tawm lossis machined) -> silicone pwm -> txhaj tshuaj molten wax -> wax qauv sib dhos -> ceramic plhaub tsev -> dewaxing -> hlau pouring. Silicone pwm yog lub replicator. Nws qhov tseeb, nto tiav, thiab ua haujlwm ntev txiav txim siab seb koj cov qauv siv quav ciab yuav ua li cas rau tus qauv tsim. Kuv tau siv sijhawm suav tsis txheeb sib cav txog Shore hardness nrog cov neeg muag khoom - softer 20A yuav ntes cov ntsiab lus zoo kawg tab sis hnav tawm tom qab 50 txhaj tshuaj, thaum 40A yuav kav ntev txog 300 tab sis muaj kev pheej hmoo tawg ntawm qhov tob tob. Tsis muaj cov lus teb thoob ntiaj teb, tsuas yog cov khoom lag luam tawm raws li ib feem geometry thiab ntim.
Ib qho mob taub hau tshwj xeeb yog cua nkag. Thaum koj ncuav silicone hla tus tswv complex nrog cov hnab tshos sib sib zog nqus lossis cov ntaub ntawv zoo, cov npuas npuas yog cov yeeb ncuab. Peb tau sim txhua qhov ua kom yuam kev: lub lauj kaub siab, lub tshuab nqus tsev degassing chambers, thiab txawm tias meticulously txhuam cov txheej nyias ntawm silicone rau hauv cov qauv ua ntej. Cov txheej txheem uas thaum kawg nyem rau ib tug series ntawm impeller prototypes koom ib tug ob-thooj ncuav thiab ib tug custom-built tilting rooj. Nws yog ib qho kev ntxhov siab, rov ua dua, tab sis nws tau txais cov npuas suav mus ze rau xoom. Qhov ntawd yog hom kev daws teeb meem uas koj yuav tsis pom hauv phau ntawv. Koj tuaj yeem pom qee qhov kev tshwm sim ntawm qhov qauv tsim theem hauv cov ntaub ntawv tshawb fawb ntawm peb lub xaib ntawm https://www.tsingtaocnc.com.
Kev xaiv ntawm silicone nws tus kheej yog kev tshawb fawb. Peb feem ntau siv platinum-kho tshuab rau lawv qhov qis qis thiab kev tsim tawm zoo heev ntawm kev nthuav dav, tshwj xeeb tshaj yog tseem ceeb rau qhov chaw uas yuav tom qab pov rau hauv stainless hlau los yog Nickel-raws li alloys. Tin-kho yog pheej yig dua, tab sis cov teeb meem inhibition thiab ntau dua shrinkage tuaj yeem qhia cov kev sib txawv uas ua kom loj hlob hauv qhov kawg hlau. Rau kev ua haujlwm siab rau cov khoom siv hydraulic xyoo tas los, peb tau ua qauv nrog ob qho tib si. Lub platinum-kho pwm tsim cov qauv siv quav ciab uas tuav ± 0.1mm kam rau ua, thaum lub tin-kho batch drifted. Tus nqi pem hauv ntej tau siab dua, tab sis nws tau txais txiaj ntsig zoo hauv lub sijhawm ua haujlwm qis los kho qhov yuam kev.
Qhov twg Mould ntsib hlau: QSY Workflow
Peb 30-xyoo keeb kwm hauv casting thiab machining tsis yog hais txog kev muaj tshuab; nws yog hais txog kev txhim kho kev sib txuas ua haujlwm. Cov silicon pwm casting txheej txheem rau cov qauv yog qhov ntsiag to, huv-chav precursor rau lub suab nrov, fiery kev muaj tiag ntawm lub foundry. Cov qauv siv quav ciab ua los ntawm cov pwm silicone zoo meej yuav muaj qhov ua tiav saum npoo uas txhais ncaj qha rau lub plhaub ceramic. Cov qauv ntxhib, pitted los ntawm cov pwm tsis zoo txhais tau hais tias koj pib lub plhaub txheej txheem ntawm qhov tsis zoo, feem ntau ua rau cov leeg lossis cov koom nrog ntawm qhov kawg casting. Peb tau kawm los tshuaj xyuas cov qauv siv quav ciab nrog kev tshuaj xyuas tib yam li qhov kawg machined ib feem.
Qhov no yog qhov uas kev koom ua ke nrog CNC machining ua tsis yog-negotiable. Txawm hais tias muaj kev nqis peev zoo tshaj plaws, feem ntau qhov ua haujlwm yuav tsum tau ua kom muaj qhov sib luag ntawm qhov chaw, cov xov, lossis cov bores nruj-tolerance. Lub cev valve peb nyuam qhuav tsim rau tus neeg siv khoom yog qhov piv txwv tseem ceeb. Cov qauv silicone-molded ciab tsim cov txheej txheem sab hauv uas yuav ua tsis tau rau tshuab. Tom qab casting nyob rau hauv duplex stainless hlau, peb lub tuam txhab CNC coj mus, machining lub flange ntsej muag thiab valve rooj rau ib tug Ra 0.8 tiav. Cov silicon pwm enabled lub geometry; CNC machining kom ntseeg tau tias kev ua haujlwm. Ib txheej txheem yog subservient rau lwm tus; lawv yuav tsum ua haujlwm tandem.
Kev poob yog ib tug xib fwb zoo dua li kev vam meej. Thaum ntxov, peb muaj ib qhov project rau ib tug series ntawm cobalt-chrome alloy hniav moj khaum. Lub geometry yog heev, nrog rab chais-nyias margins. Peb thawj silicone pwm mus kom ze siv tus qauv thaiv pwm tsim. Qhov tshwm sim? Cov qauv siv quav ciab uas tsis tu ncua fractured thaum de-molding. Cov tshuaj tsis yog silicone zoo dua, tab sis txawv pwm tsim - ntau yam, cov pwm tseem ceeb uas ua tib zoo txo kev ntxhov siab thaum lub sij hawm siv quav ciab. Nws ntxiv ib hnub rau cov txheej txheem siv tab sis tshem tawm 100% ntawm cov qauv poob. Zaj lus qhia ntawd tau hloov pauv peb li cas rau kev tsim pwm rau cov yam ntxwv me me.
Material Matters: Ntau tshaj li Hlau thiab Hlau
Thaum peb ua ntau yam nrum hlau thiab carbon steel, qhov xav tau ntawm silicon pwm casting rau cov qauv ua qhov tseem ceeb tshaj nrog cov alloys tshwj xeeb. Thaum koj tab tom cuam tshuam nrog cov khoom kim heev xws li npib tsib xee-raws li superalloys rau aerospace lossis high-wear cobalt alloys rau kev lag luam khoom noj khoom haus, tus nqi ntawm cov khoom pov tseg tsis yog cov hlau xwb - nws yog lub sij hawm poob thiab cov sij hawm ntau lawm. Qhov kev ruaj ntseg ntawm koj cov pwm silicone yog qhov tseem ceeb vim tias cov hlau nplaum no feem ntau muaj cov ntsiab lus siab melting thiab cov cwj pwm sib txawv, uas tuaj yeem ua kom muaj qhov tsis zoo me me los ntawm theem wax.
Kuv nco qab tus qauv ua haujlwm rau lub tshuab turbine hauv Inconel. Thawj ob peb lub cam khwb cia tau pom me ntsis qhov dav dav ntawm lub airfoil profile. Peb taug qab nws rov qab tsis yog lub plhaub ceramic los yog lub ncuav, tab sis rau qhov ntsuas tsis tshua muaj thermal expansion hauv silicone pwm thaum lub sij hawm siab-siab wax txhaj tshuaj. Cov pwm nws tus kheej yog distorting nyob rau hauv ntau lawm tej yam kev mob, ib yam dab tsi uas tsis tshwm sim nyob rau hauv ib tes-poured xeem. Peb yuav tsum tau hloov mus rau qhov kub-kub-kev ruaj ntseg silicone formulation thiab hloov kho cov wax txhaj tshuaj siab nkhaus. Nws yog ib qho kev hloov maj mam, kim kev sib cuam tshuam ntawm cov ntaub ntawv uas koj tsuas yog kawm los ntawm kev mob iteration.
Lub takeaway ntawm no yog hais tias kev qhia silicone rau pwm yog hopelessly vague. Koj yuav tsum xav txog ntawm tag nrho cov saw: cov siv quav ciab qhov kub thiab txias, qhov kub thiab txias, thiab qhov yuav tsum tau ua thaum kawg. Cov khoom siv pwm yog cov neeg koom nrog hauv lub cev, tsis yog lub thawv ntim khoom.
Tswv yim Pitfalls thiab Unspoken lus
Ntxiv nrog rau cov ntaub ntawv, muaj cov khoom hauv pem teb. Silicone muaj lub lauj kaub lub neej, thiab sib tov cov khoom loj rau pwm loj yog kev sib tw rau lub sijhawm. Kuv tau ua ib feem ntawm pab pawg frantically nchuav thaum cov khoom pib thicken, paub tias maj mam ncuav tuaj yeem txhais tau tias tsis muaj nuj nqis ntawm cov roj hmab. Venting yog lwm daim duab kos duab. Koj tso lub qhov cua qhov twg los tso cua kom dim yam tsis muaj teeb meem ntawm tus qauv siv quav ciab? Peb feem ntau ntxiv cov av nplaum ib ntus thaum lub sij hawm silicone ncuav, ces khawb lawv tawm tom qab los tsim cov channel zoo meej. Nws yog ib phau ntawv, yuav luag sculptural txuj ci.
Tom qab ntawd muaj kev saib xyuas. Ib qho zoo silicone pwm tuaj yeem tsim ntau pua tus qauv siv quav ciab, tab sis nws degrades. Nws absorbs noo noo los ntawm cov huab cua, nws maj mam reacts nrog tej yam wax additives, thiab nws mechanically nkees. Peb muaj lub kaw lus kaw lus rau peb cov pwm-shot suav, pom cov txiaj ntsig soj ntsuam, thiab ntsuas qhov ntev ntawm tus qauv siv quav ciab txhua 50 lub voj voog. Cov ntaub ntawv no tso cai rau peb kwv yees lub neej pwm thiab teem caij kho dua tshiab ua ntej kev poob qis. Qhov kev qhuab qhia kev ua haujlwm no yog qhov cais lub khw ua haujlwm los ntawm tus neeg muag khoom ntseeg tau zoo li QSY.
Thaum kawg, tsis txhob underestimate qhov tseem ceeb ntawm tus tswv qauv. Yog tias koj tus tswv 3D-luam tawm muaj txheej txheej, koj cov pwm silicone yuav ntes lawv, thiab koj cov qauv siv quav ciab yuav muaj, thiab koj lub plhaub ceramic yuav muaj lawv, thiab koj qhov kawg stainless hlau casting yuav muaj lawv. Qee lub sij hawm, nws tau txais txiaj ntsig ntau dua rau kev siv lub tshuab txhuas txhuas rau lub siab ntim silicone pwm, tsuas yog kom tau txais qhov pib ntawm qhov chaw zoo. Nws yog ib qho kev txheeb xyuas tus nqi-cov txiaj ntsig zoo uas tshwm sim thaum pib ntawm txhua qhov haujlwm.
Cov ntsiab lus: Nws yog ib qho cuab yeej, tsis yog Khawv koob Bullet
Yog li ntawd, los qhwv qhov no, silicon pwm casting nyob rau hauv cov ntsiab lus ntawm industrial hlau ib feem ntau lawm yog ib tug sophisticated, nthuav dav-obsessed kauj ruam nyob rau hauv ib tug ntev taug kev. Nws yog ib qho kev siv thev naus laus zis rau kev nqis peev casting, tshwj xeeb tshaj yog rau qhov nyuaj, qis-rau-nruab nrab ntim qhov chaw hla cov ntaub ntawv los ntawm cam khwb cia hlau mus rau superalloys. Nws txoj kev vam meej hinges ntawm cov khoom siv science, pwm tsim, kev tswj cov txheej txheem, thiab kev nkag siab tob ntawm tag nrho cov saw hlau uas ua raws li hauv qab no.
Lub hom phiaj tsis yog tsuas yog ua cov pwm silicone. Lub hom phiaj yog los tsim kom muaj qhov sib xws, muaj kev ntseeg siab ntawm cov qauv siv quav ciab uas ua kom pom tau zoo, zoo hlau castings. Thaum koj koom tes nrog cov chaw tsim khoom, koj tsis yog yuav lawv cov tshuab xwb; koj tab tom yuav qhov no sau, feem ntau nyuaj-yeej, txheej txheem kev paub. Qhov ntawd yog tus nqi tiag tiag - hom kev sib koom ua ke uas peb tau ua hauv Qingdao Qiangsenyuan dhau peb xyoo lawm, qhov twg lub khw qauv, qhov chaw tsim khoom, thiab CNC pem teb hais lus tib yam lus.
Thaum kawg, nws nqes los hwm tus txheej txheem. Cov pwm silicone yog ib qho kev txo hwj chim, feem ntau saib tsis tau cov cuab yeej. Tab sis kho nws raws li kev xav tom qab, thiab nws yuav dhau los ua ib qho ntawm qhov tsis ua tiav hauv koj qhov project. Muab nws qhov kev txiav txim siab nws xav tau, thiab nws dhau los ua qhov txhim khu kev qha, txuas txuas ntxiv ntawm koj tus qauv tsim thiab cov khoom siv hlau ua haujlwm.
