Thaum koj nug txog peev casting nqi, feem ntau cov neeg dhia ncaj nraim mus rau tus nqi ib-unit. Qhov ntawd yog thawj qhov yuam kev. Tus nqi tiag tiag yog lub vev xaib ntawm kev txiav txim siab, kev cuam tshuam, thiab qee zaum, zais qhov pitfalls koj tsuas yog kawm txog tom qab ib qhov project mus rau sab. Nws yeej tsis yog hais txog qhov hnyav hlau lossis qhov nyuaj ntawm daim duab; nws yog hais txog txhua yam uas tshwm sim los ntawm lub sijhawm koj ua tiav tus qauv tsim mus rau hnub koj tau txais ib lub pallet ntawm tiav castings. Kuv tau pom ntau qhov haujlwm uas qhov kev tsocai thawj zaug tau saib zoo meej, tsuas yog rau cov nuj nqis tiag tiag rau lub zais pa vim tsis muaj leej twg nug cov lus nug raug ua ntej.
Qhov nyiaj tiag mus
Cia peb ua txhaum. Cov khoom loj ntawm daim pib yog pom tseeb: cov khoom siv thiab kev ua haujlwm. Tab sis nyob rau hauv uas, qhov kev xaiv alloy yog ib tug loj tsav tsheb. Mus nrog tus qauv 316 stainless yog ib lub ntiaj teb; qhia txog nickel-raws li superalloy zoo li Inconel 718 yog lwm lub ntiaj teb nyob rau hauv cov nqe lus ntawm raw khoom tus nqi thiab cov kev txawj ntse uas yuav tsum tau los cam khwb cia kom zoo. Koj tsis yog them rau cov hlau kim dua; koj them nyiaj rau lub foundry lub peev xwm los lis nws yam tsis tau tsim ib tug siab seem nqi, uas coj kuv mus rau lub point tom ntej.
Tus nqi cuab yeej rau cov qauv siv quav ciab feem ntau yog to taub yuam kev. Rau cov qauv lossis cov ntim tsawg heev, koj tuaj yeem siv cov qauv 3D-luam tawm, uas txuag cov cuab yeej pib tab sis nce nqi tsev rau txhua tus qauv siv quav ciab. Rau kev tsim khoom, koj xav tau ib qho txhuas lossis hlau pwm. Qhov ntawd yog ib qho tseem ceeb ntawm kev siv peev nyiaj txiag. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog lawv peb xyoo caum hauv peev casting thiab machining, feem ntau yuav qhia txog qhov kev sib tsoo-qhov sib npaug. Lawv lub website, tsi.com, qhia txog lawv txoj haujlwm nrog cov alloys tshwj xeeb, uas tam sim ntawd qhia rau koj tias lawv tau teeb tsa rau cov haujlwm uas cov khoom siv thiab cov txheej txheem tswj cov nqi ntau dua qhov kev txhawj xeeb ntawm cov cuab yeej.
Tom qab ntawd muaj cov txheej txheem plhaub-tsev nws tus kheej. Tus naj npawb ntawm cov tsho tiv no ceramic, lub sij hawm ziab ntawm txhua qhov, hom stucco siv - tag nrho cov no ua rau lub sijhawm ua haujlwm thiab chaw ua haujlwm. Ib qho nyuaj nrog cov hnab tshos sib sib zog nqus yuav xav tau xya lossis yim lub tsho loj, thaum cov duab yooj yim tau txais los ntawm tsib. Txhua lub tsho tiv no ntxiv ib hnub rau lub voj voog. Yog li, koj peev casting nqi yog txuas ncaj qha rau ntev npaum li cas koj qhov chaw nyob hauv chav tsev ziab khaub ncaws.
Cov Nqi Them Nqi Tsav Tsheb (Cov Neeg Uas Tau Txais Koj)
Ntawm no yog qhov kev paub tham. Qhov yuav tsum tau ua tiav. Yog tias koj xav tau qhov chaw ua tiav ntawm 125 Ra microinches, qhov ntawd yog tus qauv. Tab sis yog tias koj qhov spec hu rau 63 Ra lossis zoo dua, qhov chaw tsim khoom yuav tsum tau kho cov ceramic slurry, siv cov stucco zoo dua, thiab muaj peev xwm ua tau ntau dua tom qab cam khwb cia. Qhov kev hloov pauv ntawd tuaj yeem ntxiv 15-20% rau koj cov nqi tsev yooj yim. Nws yog ib qho kev nthuav dav feem ntau saib tsis tau ntawm engineering kos duab.
Gating thiab venting tsim yog lwm yam uas ntsiag to pob nyiaj killer. Lub rooj vag tsis zoo tsim los txuag cov khoom siv tuaj yeem ua rau muaj kev kub ntxhov, huab cua nkag, thiab shrinkage porosity. Qhov tshwm sim? Tus nqi ntau dua. Koj tau txuag $ 2 ntawm wax tab sis tam sim no muaj 30% tsis lees paub tus nqi. Qhov tseeb peev casting nqi rau qhov zoo xwb skyrocketed. Kuv kawm qhov no txoj kev nyuaj ntawm qhov project thaum ntxov rau lub twj tso kua mis impeller; peb tau kho qhov tsim kom zoo rau kev siv wax tsawg, tab sis thawj pawg muaj 40% tsis ua hauj lwm vim qhov shrinkage. Peb yuav tsum rov tsim kho tag nrho cov rooj vag, uas txhais tau tias cov cuab yeej tshiab thiab ncua ob lub hlis.
Kev ua haujlwm tom qab casting yog feem ntau hais cais. Tus nqi puas suav nrog kev txiav tawm (tshem tawm ntawm tsob ntoo)? Nws puas suav nrog kev sib tsoo cov rooj vag? Yuav ua li cas txog kev kho cua sov los yog straightening? Ib tus neeg muab kev pabcuam puv ntoob uas sib koom ua ke CNC machining, zoo li QSY hais hauv lawv cov lus qhia, feem ntau tuaj yeem txhim kho qhov no. Muaj casting thiab machining nyob rau hauv ib lub ru tsev txo cov logistics, rov kho dua, thiab kev daws teeb meem zoo. Qhov kev sib koom ua ke tuaj yeem txo koj cov nqi av tag nrho, txawm tias thawj qhov kev tsocai casting tsis yog qhov pheej yig tshaj ntawm lub khw.
Volume vs. Complexity: The Balancing Act
Peev casting yog nto moo rau complex geometry, tab sis complexity muaj ib tug nqi. Ib feem nrog cov phab ntsa nyias (hais tias, hauv qab 2 hli) yuav tsum tau txhaj tshuaj ciab thiab lub plhaub lub tsev kom tiv thaiv kev tawg lossis ua tsis tiav. Internal cores ntxiv lwm txheej ntawm cov nqi thiab kev pheej hmoo. Rau qhov ntim qis, nws yuav tsim nyog rov tsim dua tshiab kom tsis txhob muaj lub hauv paus. Rau cov ntim siab, tus nqi ntawm cov pwm pwm tau txais amortized.
Qhov no yog qhov uas kev sib koom ua lag luam mus sij hawm ntev. Lub chaw tsim khoom uas nkag siab txog koj txoj kev lag luam tuaj yeem qhia txog kev tsim-rau-kev tsim khoom (DFM) hloov thaum ntxov. Saib ntawm QSY tsom rau lub plhaub pwm thiab peev casting hla ntau yam ntaub ntawv, lawv tau hais meej meej rau kev tuav qhov kev lag luam nyuaj. Tej zaum lawv tau qhia ntau tus neeg siv khoom ntawm qhov chaw ntxiv me ntsis cov cua ntsawj ntshab lossis lub vojvoog kom txhim kho cov txiaj ntsig zoo.
Volume luv nqi muaj, tab sis lawv tsis yog linear. Tus nqi poob loj tshaj plaws tshwm sim los ntawm tus qauv (1-10 daim) mus rau kev ua haujlwm me me (100-500 daim). Tom qab ntawd, cov nyiaj khaws cia rau ib chav poob qis. Koj feem ntau txuag ntawm cov cuab yeej amortized thiab teeb tsa lub sijhawm. Cov khoom siv thiab kev ua haujlwm ncaj qha rau ib thooj dhau los ua qhov tseem ceeb.
Kev xaiv cov khoom siv: Qhov sib npaug ntawm tus nqi tseem ceeb
Koj tsis tuaj yeem tham tus nqi yam tsis hais cov ntaub ntawv. Carbon steels yog lub hauv paus. Stainless hlau (304, 316, 17-4 PH) yog ib kauj ruam. Tab sis thaum koj nkag mus rau hauv cov cobalt-based lossis nickel-based alloys QSY cov npe, koj nyob hauv ib pab koomtes sib txawv. Cov alloys no tsis tsuas yog kim ib kilogram xwb, tab sis lawv kuj nyuaj rau yaj, ncuav, thiab ua kom tiav. Lawv xav tau cov txheej txheem nruj dua thiab feem ntau tshwj xeeb kev kho cua sov.
Tus nqi ntawm kev siv cov alloys no tsis yog cov kab ntawv sau nyiaj xwb. Nws yog qhov kev lees paub tias qhov chaw tsim khoom muaj cov kws tshaj lij metallurgical los tswj cov khoom siv hlau. Ib lub chaw tsim khoom pheej yig dua tuaj yeem muab pov rau Inconel, tab sis yog tias lawv tsis tswj qhov kub thiab txias los yog lub voj voog txias kom raug, koj yuav xaus nrog ib feem uas zoo li tab sis ua tsis tiav hauv kev pabcuam. Qhov ntawd yog qhov kawg, tus nqi puas tsuaj.
Qee zaum, txoj kev xaiv yog siv cov khoom kim dua los ntawm qhov pib. Kuv nco qab lub valve tivthaiv thawj zaug teev nyob rau hauv tus qauv stainless. Nws ua tsis tau raws li corrosion thiab kub. Peb hloov mus rau qib siab dua duplex stainless, uas ua rau ob npaug ntawm cov khoom peev casting nqi. Txawm li cas los xij, cov khoom siv lub neej tau nce tsib npaug, ua rau tag nrho cov nqi ntawm cov tswv cuab qis dua. Ib tug zoo foundry khub pab koj pom daim duab loj.
Nkag mus rau Qhov Tseeb Quote
Yog li, ua li cas koj thiaj li tau txais ib nqe lus hais txog qhov tseeb? Muab txhua yam. Tus qauv 3D yog qhov pib, tab sis nws tsis txaus. Koj yuav tsum tau qhia meej: cov khoom siv qib (tsis yog cov hlau tsis muaj steel), yuav tsum muaj cov khoom siv kho tshuab, kev kho cua sov, cov qauv siv tau (xws li ASTM A802 rau kev soj ntsuam saum npoo), thiab kev xav tau tom qab ua tiav. Qhov ntau vague koj yog, qhov ntau contingency lub foundry yuav tsim rau hauv tus nqi los npog lawv cov kev pheej hmoo.
Thov kom muaj kev sib cais. Ib daim ntawv pov thawj pob tshab tuaj yeem cais tus nqi cuab yeej, nqi tsev casting, thiab tus nqi tom qab ua tiav. Qhov no yuav pab koj nkag siab qhov twg cov nyiaj yuav mus thiab qhov twg yuav muaj chaw rau kev sib tham lossis rov tsim dua.
Thaum kawg, xav txog tus nqi tag nrho, tsis yog tus nqi xwb. Ib tug foundry nrog integrated CNC machining muaj peev xwm, zoo li qhov tau piav qhia ntawm tsi.com, muaj kev tswj. Lawv lis tag nrho cov txheej txheem los ntawm molten hlau mus rau ib tug machined, npaj-rau-nruab feem. Qhov no txo koj lub nra ntawm kev tswj hwm, ua kom yooj yim rau kev taug qab zoo (ib lub luag haujlwm ntawm lub luag haujlwm), thiab feem ntau ua rau zoo tag nrho vim tias pab pawg machining nkag siab txog cov txheej txheem casting. Qhov kev sib koom ua ke no muaj qhov muaj txiaj ntsig uas cov pob txha liab qab ib-kilo casting quote yuav tsis qhia. Thaum kawg, qhov tseeb peev casting nqi yog tus nqi tau txais kev ntseeg siab, ua haujlwm tau raws li txhua yam koj xav tau, raws sijhawm, txhua lub sijhawm. Tag nrho lwm yam tsuas yog kev kwv yees xwb.
