Thaum ib tug neeg tshawb nrhiav 'zoo tshaj plaws ciab rau poob ciab casting', lawv feem ntau cia siab rau qhov yooj yim, ib-size-fits-tag nrho cov lus teb. Qhov ntawd yog thawj qhov kev xav tsis zoo. Tsis muaj ib qho 'zoo tshaj' siv quav ciab; Nws yog ntau ntxiv txog txoj cai siv quav ciab rau txoj haujlwm tshwj xeeb - koj cov qauv tsis yooj yim, cov hlau uas koj tab tom nchuav, koj lub khw kev nyab xeeb, thiab txawm tias koj lub voj voog hlawv. Kuv tau pom ntau tus neeg tuaj tshiab tau txiav txim siab 'premium' wax raws li specs ib leeg, tsuas yog xaus nrog cov qauv tawg lossis cov tshauv txaus ntshai. Qhov kev xaiv tiag tiag yog los ntawm kev nkag siab txog kev lag luam tawm.
Qhov Zoo Tshaj Plaws: Yam Koj tab tom nrhiav tiag tiag
Tsis nco qab daim ntawv lo. Koj tab tom ntsuas qhov sib xyaw. Cov khoom tseem ceeb yog qhov ruaj khov ntawm qhov ntev (nws yuav tsum tsis txhob ua rau thaum tsaus ntuj), cov hmoov tshauv tsawg (tseem ceeb rau cov kab noj hniav huv hauv high-temperature alloys), thiab zoo carving / machining zog yog tias koj tab tom kho lossis ua qauv ncaj qha. Ib lub wax uas nyuaj heev tuaj yeem nkig thiab nyuaj rau qhov rooj; ib qho uas mos heev yuav poob rau hauv lub plhaub los yog deform nyob rau hauv nws tus kheej qhov hnyav hauv ib tsob ntoo sib dhos. Kuv nyiam categorize lawv los ntawm thawj daim ntawv thov: txhaj tshuaj, qauv / patching, thiab dipping.
Rau kev txhaj tshuaj, ntws thiab contraction tus nqi yog txhua yam. Ib lub wax yuav tsum tau sau cov pwm kom tiav thiab tom qab ntawd txo qis kom deb ntawm nws kom yooj yim tshem tawm. Kuv tau txais txiaj ntsig zoo nrog qee qhov hloov pauv paraffin-microcrystalline blends. Lawv muab qhov sib npaug zoo. Ntshiab beeswax, feem ntau romanticized, feem ntau yog mos heev thiab sib txawv rau feem ntau ntau lawm ua hauj lwm, tab sis nws yog ib qho zoo nkauj rau tej daim duab uas tes-workability yog qhov tseem ceeb.
Cov ntsiab lus tshauv yog tsis sib tham rau precision castings, tshwj xeeb tshaj yog nyob rau hauv aerospace los yog kev kho mob daim ntaub ntawv uas tej seem yuav tsim inclusions. Qee cov khoom siv hluavtaws polymer-raws li khav theeb zero tshauv, uas yog qhov zoo heev, tab sis lawv tuaj yeem ua npau suav phem tshem tawm ntawm cov cuab yeej yog tias lawv mus rau qhov chaw lawv tsis tsim nyog. Nws yog ib qho kev ntsuas tsis tu ncua.
Txhaj vs. Tes-Formed: Ib tug tsiaj nyaum sib txawv rau tag nrho
Cov quav ciab koj siv hauv lub tshuab txhaj tshuaj tsis siv neeg yog cov tsiaj sib txawv ntawm qhov thaiv koj kos lossis daim ntawv koj poob. Tshuab waxes yog tsim los rau qhov kub thiab txias. Ntawm kuv lub khw dhau los, peb tau siv cov tshuaj ntsuab tshuaj ntsuab nruab nrab los ntawm cov neeg muag khoom loj rau feem ntau ntawm peb cov haujlwm stainless hlau. Nws ntseeg tau. Tab sis thaum peb tau ua txoj haujlwm uas xav tau cov ntu nyias heev rau cov khoom siv turbine, nws ua tsis tiav - nws txias sai heev thiab tsim cov kab ntws. Peb hloov mus rau softer, qis-viscosity formulation nrog ib tug ntau dua txhaj tshuaj kub, uas daws qhov sau qhov teeb meem tab sis ces xav kom peb lis cov qauv nrog ntau yam kev saib xyuas thaum sib dhos. Txhua qhov kev hloov pauv cascades.
Rau tes ua hauj lwm, xws li patching seams los yog tsim cov yam ntxwv, kuv khaws ob hom ntawm lub rooj ntev zaum: ib tug nplaum, pliable ' nplaum wax' rau kev sib koom ceev thiab ib qho nyuaj, ntau sculptable 'tooling wax' rau sau thiab shaping. Cov nplaum nplaum yog qhov tseem ceeb ntawm cov kua nplaum uas tswj tau. Cov cuab yeej siv quav ciab yuav tsum muaj zog txaus los tuav lub npoo npoo thaum koj txhuam nws tab sis mos txaus kom smoothed nrog rab riam sov. Kuv tau txais kuv los ntawm ob peb tus neeg muab khoom tshwj xeeb; qhov tseeb hom tseem ceeb tsawg dua nws qhov sib xws ntawm batch mus rau batch.
Qhov Kev Ntsuam Xyuas Ntiaj Teb Tiag: Burnout yog qhov twg qhov tseeb nthuav tawm nws tus kheej
Koj tuaj yeem nyiam cov quav ciab ntawm lub rooj ntev zaum, tab sis qhov cub burnout yog tus txiav txim zaum kawg. Lub hom phiaj huv, ua tiav melt-out yog lub hom phiaj. Qee cov waxes, tshwj xeeb tshaj yog cov uas muaj cov ntsiab lus muab tub lim siab, tuaj yeem tawm hauv qhov tawv nqaij, tarry residue uas thaiv cov slurry ntws nyob rau hauv lub plhaub tom ntej los yog, qhov phem tshaj, tawm carbonaceous tsis xws luag nyob rau hauv lub kawg hlau. Kuv kawm qhov no nyuaj heev thaum ntxov. Peb tau siv cov khoom pheej yig dua, dav dav siv quav ciab rau qee qhov carbon steel fittings. Cov castings tseem tuaj tawm nrog nto pitting. Tom qab txiav txim tawm slurry thiab hlau teeb meem, peb taug qab nws rov qab mus rau quav ciab residue sintering hauv pwm. Hloov mus rau cov hmoov tshauv qis, thiab qhov teeb meem ploj mus. Tus nqi ib kilo siab dua, tab sis tus nqi seem poob qis.
Burnout voj voog optimization yog khi rau koj cov quav ciab. Cov txheej txheem ramp-and-tuav cov sij hawm nyob rau hauv lub cub tawg phau ntawv yog cia li pib cov ntsiab lus. Nrog rau kev sib tov tshiab, peb ib txwm khiav ob peb lub plhaub nrog cov thermocouples kom pom tseeb tias nws coj li cas. Puas yog nws nthuav ntau dhau thaum pib ua kom sov, pheej hmoo lub plhaub tawg? Nws puas tag nrho volatilize los ntawm lub hom phiaj kub? Qhov kev sib txuas ntawm tes no yog ib yam uas koj tsis tau txais los ntawm cov ntaub ntawv.
Material Matters: Vim li cas koj cov Alloy cuam tshuam koj qhov kev xaiv ciab
Qhov no yog ib lub ntsiab lus feem ntau overlooked. Lub alloy koj tab tom nrum dictates ntau tshaj li lub plhaub refractory. Pouring kub nickel-based superalloy? Koj xav tau cov quav ciab nrog cov hmoov tshauv qis tshaj plaws vim tias cov pwm no raug rho tawm ntawm qhov kub thiab txias, thiab cov khoom seem yuav ci rau hauv ceramic. Rau qis-kub alloys xws li bronze los yog txhuas, koj muaj ntau leeway, thiab yam xws li nqi thiab yooj yim ntawm kev siv tej zaum yuav ua ntej.
Cov tuam txhab uas lis ntau yam khoom siv, xws li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), uas ua haujlwm los ntawm cam khwb cia hlau mus rau cobalt thiab npib tsib xee-raws li alloys, tej zaum yuav tuav ib lub tsev qiv ntawv me me ntawm waxes. Koj tsis tuaj yeem siv tib txoj kev siv quav ciab rau ib qho yooj yim hlau manifold thiab ib qho kev phais phais qhov tseeb. Lawv peb caug xyoo hauv plhaub molding thiab peev casting yuav tau nthuav tawm lawv mus rau ntau qhov kev sib tw uas suav tsis txheeb. Qhov kev xaiv dhau los ua ib feem ntawm cov txheej txheem engineering rau txhua ntu. Kuv xav twv lawv cov kws tshaj lij muaj cov kev xav zoo uas siv quav ciab ua haujlwm zoo tshaj plaws rau lawv cov txheej txheem plhaub tshwj xeeb thiab cov kev coj ua kub hnyiab, kev paub uas tau tsim los ntawm pom ntau txhiab tus pwm nkag mus rau hauv qhov cub.
Cov kev txiav txim siab zoo tshaj li daim ntawv teev cov ntaub ntawv
Kev khaws cia thiab tuav yog loj heev. Waxes rhiab rau qhov kub thiab txias. Lub pallet sab laug hauv lub thawv ntim khoom kub tuaj yeem dhau los ua kev sib xyaw ua ke. Peb khaws peb cov khoom hauv chav tswj kev nyab xeeb. Txawm li cas los xij, cov av noo raws caij nyoog tuaj yeem cuam tshuam rau saum npoo ntawm cov qauv thaum lub sij hawm sib dhos, yuav tsum tau hloov kho hauv cov txheej txheem dewaxing. Nws yog cov no mundane, khw-hauv pem teb qhov tseeb uas txhais tau tias 'zoo tshaj' ntau dua li kev kuaj sim.
Tom qab ntawd muaj kev ntseeg tau ntawm tus neeg muag khoom. Puas yog qhov sib xyaw ua ke ntawm kev txiav txim mus rau kev txiav txim? Puas yog kev txhawb nqa kev pab cuam thaum koj muaj teeb meem? Kuv tau daig nrog tus neeg muag khoom tsis yog vim tias lawv cov quav ciab yog qhov zoo tshaj plaws, tab sis vim tias lawv cov khoom tau kwv yees tau thiab lawv cov neeg sawv cev tuaj yeem daws teeb meem nrog kuv hauv xov tooj. Nyob rau hauv ib lub sij hawm ntau lawm, kev kwv yees feem ntau muaj txiaj ntsig ntau dua li qhov kev ua tau zoo tshaj plaws los ntawm qhov tsis tau kuaj 'zoo tshaj' siv quav ciab.
Yog li, kuv lub tswv yim? Pib nrog lub koob npe nrov, kev lag luam-tus qauv txhaj tshuaj ciab rau koj txoj haujlwm tseem ceeb. Khaws ib qho kev txhim khu kev qha qauv ciab ntawm tes. Tom qab ntawd, sim. Order me me ntawm ntau hom rau kev xeem khiav. Sau cov txiaj ntsig - tsis yog qhov kev ua yeeb yam nkaus xwb, tab sis nws coj li cas ntawm txhua kauj ruam. Qhov 'zoo tshaj plaws wax' yog ib qho uas ploj ntawm koj cov txheej txheem, ua rau koj tsis muaj dab tsi xav txog tsuas yog lub plhaub zoo meej npaj rau hlau. Qhov ntawd yog lub hom phiaj. Nws yog tsawg dua txog ib yam khoom thiab ntau ntxiv txog kev ua tiav lub xeev qhov twg cov khoom siv tsis tas yuav hloov pauv. Qhov ntawd yog thaum koj paub tias koj tau pom koj qhov kev sib tw.
