Thaum cov neeg feem coob hnov cov tuam txhab poob wax casting, lawv pom qhov tsaus ntuj, plua plav qhov chaw ua cov trinkets. Qhov ntawd yog thawj qhov kev xav tsis zoo. Qhov kev muaj tiag yog ib qho kev txawj ntse heev, feem ntau ntxhov siab, thiab muaj txiaj ntsig zoo heev ntawm kev xa cov qauv siv quav ciab tsis yooj yim rau hauv cov khoom siv hlau muaj zog, muaj kev ntseeg siab. Nws tsis yog tsuas yog ua tej yam; nws yog hais txog kev daws teeb meem ntawm geometry, cov khoom siv, thiab cov nqi uas lwm cov txheej txheem kov tsis tau.
Lub Core tsis yog Wax, Nws yog Plhaub
Txhua tus fixates rau ntawm wax. Tseeb, tus qauv yog ib qho tseem ceeb, tab sis cov khawv koob tiag tiag - thiab qhov twg cov khw feem ntau qhia lawv cov mettle - yog nyob rau hauv lub ceramic plhaub tsev. Nov yog qhov chaw ua lag luam nyiam Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) cais nws tus kheej. Nws tsis yog kev ua haujlwm dip-and-dunk. Nws yog ib qho kev tswj, ntau lub voj voog ntawm dipping cov quav ciab rau hauv slurry, stuccoing nrog refractory xuab zeb, thiab ziab. Rov ua dua. Xya, yim, qee zaum cuaj zaug. Qhov tuab, qhov chaw ziab (humidity yog tus yeeb ncuab), granularity ntawm stucco-txhua txheej yog qhov kev txiav txim siab uas cuam tshuam rau qhov kawg ntawm qhov kawg thiab qhov seem stability. Tau nws tsis ncaj ncees lawm, thiab koj tau txais lub plhaub uas tawg thaum lub sij hawm dewaxing (feem ntau nyob rau hauv ib qho autoclave) los yog, phem dua, thaum lub sij hawm ncuav.
Kuv nco qab ib txoj hauj lwm rau lub twj tso kua mis impeller, ib qho nyuaj, nyias-vaned tsim nyob rau hauv 316 stainless. Cov wax zoo tag nrho. Thawj ob peb lub plhaub txheej yog phau ntawv. Tom qab ntawd peb ntaus ib tug humid spell. Pab pawg tau thawb kom teem sijhawm, dipping ua ntej txheej dhau los tau qhuav tag. Qhov tshwm sim? Ib lub plhaub zoo nkauj uas, thaum tua, tsim cov kab nrib pleb. Cov hlau molten nkag mus, tsim cov fins ntawm lub vanes uas tsis tuaj yeem tshem tawm yam tsis muaj kev cuam tshuam rau qhov profile. Tag nrho poob. Qhov kev ua tsis tiav ntawd yog ib qho kev ua phem rau kev hwm tus txheej txheem ntawm daim ntawv qhia hnub. Nws yog ib zaj lus qhia hauv kev ua haujlwm uas tau siv sijhawm ntau xyoo, zoo li QSY cov ntaub ntawv 30 xyoo. Koj tsis tuaj yeem maj cov ceramics.
Lub plhaub no, ib zaug raug rho tawm haujlwm, dhau los ua monolithic, tsis muaj pwm. Qhov ntawd yog qhov txiaj ntsig tseem ceeb. Tsis muaj cov kab sib cais, tsis muaj cov kaum sab xis. Nws tso cai rau cov insane geometries - sab hauv cov lus, undercuts, organic duab - uas yog machinable nkaus xwb nrog huab nqi thiab nyuaj. Lub plhaub yog qhov chaw tsis zoo uas txhais tau tias lub peev xwm ntawm ib feem.
Cov khoom yog qhov twg qhov kev ua si hloov
Poob ciab casting tsis yog rau bronze pej thuam ntxiv lawm. Cov khoom siv spectrum yog loj heev, thiab kev xaiv dictates txhua yam los ntawm lub ncuav kub mus rau tom qab-casting tshav kub kho. Qhov no yog lwm qhov chaw uas kev paub tsis muaj kev sib tham. Ua hauj lwm nrog carbon steel yog ib yam; nchuav Nickel-raws li alloys los yog cobalt-based alloys yog ib tug tsiaj nyaum sib txawv kiag li.
Cov superalloys no muaj cov ntsiab lus melting siab thiab feem ntau reactive. Lawv thov kom muaj lub plhaub tshwj xeeb los tiv thaiv kev sib cuam tshuam tshuaj lom neeg ntawm qhov kub thiab txias. Lub rooj vag system-cov kab uas pub hlau rau hauv pwm kab noj hniav-yuav tsum tau tsim txawv. Koj xav tau cov hauv paus loj dua thiab cov rooj sib tham ntau dua los xyuas kom muaj kev noj zaub mov zoo thiab txo qis qhov porosity hauv cov khoom kim heev. Ib qho kev tsim rooj vag dav dav yuav tshem tawm $ 10,000 batch ntawm Inconel hauv feeb.
Saib ntawm tus neeg muag khoom cov npe khoom qhia rau koj ntau. Thaum koj pom ib lub tuam txhab npe tsis yog xwb stainless hlau thiab nrum hlau, tab sis tshwj xeeb hu tawm cov alloys tshwj xeeb, nws qhia tau hais tias lub foundry nruab rau kev ua haujlwm siab heev. Nws txhais tau hais tias lawv muaj kev paub txog metallurgical thiab lub tshuab hluav taws xob los daws nws. Nws yog ib daim paib ntsiag to ntawm kev muaj peev xwm. Cov lus qhia luv luv rau QSY lub vev xaib (tsi.com) tau txais txoj cai no-nws coj nrog cov txheej txheem tab sis tam sim ntawd anchors lawv hauv cov ntaub ntawv, suav nrog cov alloys tshwj xeeb. Qhov ntawd yog tus kws kho mob cov ntsiab lus.
Kev sib yuav Inevitable: Casting thiab CNC
Nov yog qhov tseeb nyuaj: tsis muaj peev txheej casting tawm zoo meej. Ib txwm muaj qee qhov kev ntxuav. Flash ntawm qhov rooj sib txuas, me me nodules los ntawm lub plhaub zoo nkauj.
