Thaum tib neeg nug txog 'poob ciab casting nqi', feem ntau lawv tsuas yog nrhiav tus nqi ib thooj. Qhov ntawd yog thawj qhov yuam kev. Tus nqi tsis yog ib tus lej uas koj rub los ntawm daim ntawv qhia; nws yog ib qho kev sib tham uas pib nrog cov geometry hauv koj cov ntaub ntawv CAD thiab xaus nrog qhov kawg ntawm koj txhais tes. Kuv tau pom ntau qhov project tau derailed vim ib tug neeg piv cov nqe lus rau ib qho yooj yim bronze knob rau ib tug complex, nyias-walled stainless hlau manifold thiab xav tias lub foundry twb ripping lawv tawm. Tus nqi tiag tiag yog nyob rau hauv tag nrho ntawm kev txiav txim siab ntev ua ntej cov quav ciab txawm txhaj.
Lub Foundation: Nws Txhua Yam Pib Nrog Tus Qauv
Koj tsis tuaj yeem tham tus nqi yam tsis tau tham txog tus qauv. Ib qho yooj yim, khoom qauv rau lub iav? Tus nqi pheej yig hauv tooling. Tab sis yog tias koj ib feem muaj cov kev sib txuas sab hauv, undercuts, los yog yuav tsum tau muaj ntau qhov swb txhuas pwm, cov cuab yeej pib peev tuaj yeem nce siab. Kuv nco qab tus neeg siv khoom uas tsim lub vaj tsev zoo nkauj nrog cov txheej txheem sab hauv lattice kom txo qhov hnyav. Zoo nkauj tsim, tab sis cov pwm xav tau collapsible ceramic cores thiab ntau daim pwm sib dhos. Cov ploj wax casting txheej txheem nws tus kheej yog tus qauv, tab sis tus qauv tus nqi ua ob npaug rau qhov project tus nqi nkag. Qhov ntawd yog cov kab lus zais ntau nco.
Tom qab ntawd muaj cov khoom siv quav ciab nws tus kheej. Standard qauv ciab yog ib tug nqi. Tab sis rau qhov xav tau qhov kev ruaj ntseg zoo-xav ntev, nyias ntu uas tuaj yeem ua rau warp-koj yuav xav tau cov khoom ntim lossis cov khoom siv polymer-blend wax. Qhov ntawd ntxiv tej zaum 15-25% rau koj cov nqi khoom siv tawm ntawm tus puav. Nws yog qhov tsim nyog phem qee zaum. Peb ib zaug sim txuag nyiaj ntawm kev khiav ntawm lub cev valve los ntawm kev siv cov khoom siv pheej yig dua. Qhov tshwm sim? Raws li, hloov maj mam distortion nyob rau hauv lub bore kev sib raug zoo uas tsis tau ntes mus txog rau thaum machining, scrapping ib tug tag nrho batch. Cov kev txuag tau obliterated kaum zaug dhau.
Volume yog lwm sab ntawm tus qauv npib. Ib $10,000 pwm amortized tshaj 50 daim yog lim hiam. Ntau tshaj 50,000 daim, nws dhau los ua negligible. Qhov no yog qhov chaw uas tus neeg koom tes zoo yuav tsum coj koj. Rau qhov tsawg-ntim, siab-complexity qhov chaw, qee zaum 3D-luam qauv los yog txawm tias ncaj binder jetting ntawm lub plhaub ceramic yog kev lag luam ntau dua, txawm tias muaj nqi ntau dua ib chav tsev. Nws bypasses lub zog tooling nkaus. Cov tuam txhab uas muaj ob qho tib si ib txwm thiab niaj hnub txoj kev, nyiam Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), muaj qhov zoo ntawm no. Lawv tuaj yeem ua kom pom tseeb txoj hauv kev zoo tshaj plaws rau koj lub ntim, txawm tias nws yog classic peev casting cuab yeej los yog ib txoj hauv kev hybrid.
Lub Plhaub Game: Cov Nqi Ceramic thiab Lub Sijhawm Txheej Txheem
Cov txheej txheem tsim lub plhaub ceramic yog qhov uas tus nqi ntawm ib chav tsev tau muab ci rau hauv. Txhua lub dip, xuab zeb, thiab ziab lub voj voog ntxiv zog, lub zog, thiab cov khoom siv. Ib qho tuab, hnyav yuav xav tau 7-9 txheej ntawm ceramic slurry thiab stucco. Ib qho me me, tshav kub-resistant alloy ib feem rau aerospace tej zaum yuav xav tau tshwj xeeb zirconia-raws li lub ntsej muag lub tsho thiab ntau txheej rau kev ncaj ncees, ntxiv dag zog rau lub ntsej muag. casting nqi.
Plhaub tsis ua hauj lwm yog ib tug ntsiag to pob nyiaj killer. Yog hais tias lub plhaub tawg thaum lub sij hawm dewaxing (tus txheej txheem autoclave los yog flash fire process) los yog thaum lub sij hawm ncuav, koj poob tsis tau tsuas yog siv quav ciab, tab sis tag nrho cov kev ua hauj lwm thiab cov khoom siv nyob rau hauv lub plhaub. Kev tswj kom qhuav ib puag ncig-humidity thiab kub-yog qhov tseem ceeb. Nyob rau hauv ib qho ntawm peb cov chaw qub uas tsis muaj kev tswj hwm huab cua kom qhuav, peb yuav pom lub plhaub tawg ntawm lub caij ntuj no. Tus nqi tsis yog nyob rau hauv lub plhaub ploj; nws yog nyob rau hauv lub sij hawm ntau lawm thiab frantic overtime mus ntaus hnub xa khoom. Niaj hnub nimno foundries nrog tswj ib puag ncig ci qhov kev cia siab rau hauv lawv cov nqi.
Nws kuj tseem hais txog lub sijhawm voj voog. Lub plhaub uas siv sijhawm 5 hnub los tsim kev sib piv rau 7 hnub (siv cov tshuab ziab khaub ncaws siab lossis cov tshuab sib txawv sib txawv) khi koj cov peev thiab hauv pem teb qhov chaw sib txawv. Tus nqi nyiaj siv ua haujlwm no tau faib thoob plaws txhua txoj haujlwm hauv khw. Ib qho kev sib xyaw ua ke, cov khoom siv qis qis tus nqi yuav txawv ntawm cov kab mob siab ua haujlwm ntau lab ntawm tib lub taub hau golf. Thaum koj tau txais ib qho kev tsocai, koj kuj tau them rau lub khw qhov kev ua tau zoo - lossis nws qhov ua tsis tau zoo.
Cov Khoom Hlau: Ntau tshaj li Tus Nqi Ib Kilo
Obviously, kev xaiv alloy yog tus tsav tsheb loj. 304 stainless versus 316. Carbon steel piv rau nickel-raws li superalloy zoo li Inconel 718. Cov khoom siv raw cov nqi sib txawv tuaj yeem yog 10x. Tab sis qhov ntawd yog qhov pib xwb. Tus cwj pwm yaj hloov txhua yam. Superalloys feem ntau xav tau lub tshuab nqus tsev melting thiab pouring, uas yog ib qho khoom siv kim heev thiab cov nqi ua haujlwm piv rau qhov qhib cua induction rauv rau cam khwb cia hlau.
Yield yog lo lus khawv koob ntawm no. Ntau npaum li cas ntawm cov hlau koj nchuav mus rau hauv qhov kawg? Ib qho tuab, chunky tsim yuav muaj 70% tawm los. Ib feem nrog ntev, nyias fins thiab lub rooj vag nyuaj yuav muaj 40% tawm los. Cov hlau uas ploj lawm - cov sprue, khiav, rooj vag, thiab risers - yog rov siv dua, tab sis koj tseem them rau qhov pib yaj, lub zog kom yaj nws, thiab poob los ntawm oxidation (kho shrinkage). Kuv ib txwm qhia rau cov neeg tsim qauv: tsim kom muaj txiaj ntsig. Qee lub sij hawm ntxiv 1 hli tuab rau phab ntsa tuaj yeem txhim kho kev sau thiab txo cov khoom seem, txuag cov nqi hlau uas deb tshaj qhov hnyav ntxiv.
Qhov no yog qhov chaw tsim khoom ntawm cov khoom tshwj xeeb tseem ceeb. Ib lub khw zoo li QSY, uas teev cov kev paub tshwj xeeb nrog cobalt-based thiab npib tsib xee-raws li alloys, tau ua kom zoo dua lawv qhov tsis zoo rau cov ntaub ntawv tsis yooj yim no. Lawv paub qhov tseeb pouring kub, plhaub preheat, thiab txias npaum li cas xav tau rau ib tug zoo yield ntawm Hastelloy ib feem. Siv lub hauv paus uas feem ntau ua hlau cam khwb cia hlau rau koj qhov project stainless hlau tej zaum yuav pheej yig dua ntawm tus nqi, tab sis lawv txoj kev kawm nkhaus thiab cov txiaj ntsig qis dua tuaj yeem ua qhov kawg. poob ciab casting nqi siab dua.
Tom qab Casting: Qhov Chaw Ncauj 50% Nyob
Qhov no yog qhov kev poob siab loj tshaj plaws rau cov neeg tuaj tshiab. Tus nqi ntawm raw casting yog feem ntau tsuas yog ib nrab ntawm zaj dab neeg. Lub casting tawm los nrog cov rooj vag txuas, qhov zoo nkauj ntawm cov ceramic, thiab ua tau me fins ntawm txoj kab sib faib. Txhua yam tom qab shakeout yog tus nqi ua haujlwm thib ob.
Kev txiav tawm yog thawj zaug. Los ntawm txhais tes txiav tawm nrog lub saw yog siv zog heev. Automated abrasive txiav los yog band sawing yog zoo dua. Rau high-ntim, robotic cutoff chaw nres tsheb yog yuav tsum tau. Ces sib tsoo. Tshem tawm lub rooj vag stubs thiab smoothing nto yog kev ua haujlwm huv. Ib qho nyuaj nrog cov rooj vag hauv thaj chaw nyuaj tuaj yeem siv lub tshuab sib tsoo 30 feeb, qhov yooj yim ib feem yuav siv 2. Qhov kev ua haujlwm no ntxiv nrawm.
Tom qab ntawd, kev kho cua sov. Puas yog nws yuav tsum tau ua kom muaj kev ntxhov siab? Rau kev ua tiav cov khoom siv kho tshuab tshwj xeeb? Qhov ntawd yog lwm lub voj voog hluav taws xob, lwm kauj ruam logistics, lwm tus nqi. Kev kuaj tsis yog kev puas tsuaj (NDT). Puas yog qhov yuav tsum tau X-ray, dye penetrant, lossis kuaj ultrasonic? Txhua qhov kev xeem ntxiv sijhawm thiab tus nqi tshwj xeeb. Thaum kawg, txhua yam CNC machining. Feem ntau cov peev castings yog ze-net-puab, tab sis tseem ceeb interfaces yuav luag ib txwm xav tau machining. Lub tuam txhab muaj peev xwm ua haujlwm hauv tsev, zoo li qhov QSY muab, yog tus nqi txuag nyiaj ntau. Bundling casting thiab machining tshem tawm shipping, rov kho dua, thiab kev sib txuas lus sib txawv ntawm cov neeg muag khoom sib txawv. Tus nqi ntawm lub mismachined casting vim yog ib qho kev txhais lus tsis raug ntawm cov tuam txhab tuaj yeem ua rau muaj kev puas tsuaj loj.
Muab Nws Ua Ke: Cov Quote Tiag Tiag
Yog li, thaum koj tau txais ib daim ntawv tsocai, koj tsis tau them nyiaj rau lub casting. Koj tau them rau: Qauv / cuab yeej amortization, wax txhaj, plhaub tsev ua haujlwm & cov ntaub ntawv, hlau yaj & ncuav (hloov rau cov khoom tawm), shakeout, txiav tawm, sib tsoo, muaj peev xwm kho cua sov, muaj peev xwm NDT, thiab kev tswj hwm nyiaj siv ua haujlwm.
