Aluminium casting yog ib txoj hauv kev los ua kom muaj kev siab ntev thiab ua haujlwm zoo los ntawm kev nchuav molten aluminium rau hauv cov qauv tsim thiab precision engineered tuag, pwm, lossis daim ntawv. Nws yog ib tug npaum txheej txheem rau zus tau tej cov complex, intricate, cov ncauj lus kom ntxaws qhov chaw uas raws nraim haum cov specifications ntawm tus thawj tsim.
Aluminium Casting txheej txheem
1.Pwm Casting
Feem ntau ntawm cov nqi ntawm txhuas mus tas li pwm casting yog machining thiab shaping ntawm pwm, uas feem ntau yog ua los ntawm grey hlau los yog hlau. Cov pwm yog zoo li tus geometric duab ntawm qhov tsim ib feem nrog cov specifications thiab cov duab ntawm ib feem muab faib ua ob halves. Nyob rau hauv cov txheej txheem txhaj tshuaj, ib nrab ntawm cov pwm yog nruj nreem kaw kom tsis txhob muaj huab cua los yog muaj kab mob. Cov pwm yog rhuab ua ntej pouring ntawm lub molten aluminium, uas yuav ladled, poured, los yog txhaj.
Thaum ua tiav cov txheej txheem, cov pwm raug tso cai kom txias kom tso cai rau cov txhuas feem kom khov. Thaum txias, ib feem yog tshem tawm sai sai ntawm cov pwm los tiv thaiv kev tsim ntawm qhov tsis xws luag.
Txawm hais tias qhov yooj yim npaum li cas cov txheej txheem yuav zoo li, nws yog ib qho kev tshawb fawb thiab kev tsim qauv tsim los tsim cov khoom ntim siab.
2.Xuab zeb Casting
Cov txheej txheem xuab zeb casting yuav tsum ntim cov xuab zeb nyob ib ncig ntawm cov qauv siv rov qab uas muaj cov duab, cov ntsiab lus, thiab kev teeb tsa ntawm cov khoom kawg. Muaj nyob rau hauv cov qauv yog risers uas tso cai rau cov hlau molten yuav tsum tau poured rau hauv pwm thiab rau kub aluminium pub lub casting thaum solidification los tiv thaiv shrinkage porosity.
Muaj nyob rau hauv cov qauv yog ib tug sprue uas tso cai rau molten hlau mus rau hauv lub pwm. Qhov ntev ntawm cov qauv yog me ntsis loj dua cov khoom kom suav rau shrinkage thaum lub caij txias. Cov xuab zeb muaj qhov hnyav thiab lub zog los tswj cov qauv ntawm cov qauv thiab tiv taus kev cuam tshuam nrog cov hlau molten.
4.Nqus Tuag Casting Lub tshuab nqus tsev tuag casting siv lub tswb nrov hauv lub tshuab cua uas muaj qhov qhib qhib rau hauv qab thiab lub tshuab nqus tsev nyob rau saum. Cov txheej txheem pib los ntawm submerging lub sprue hauv qab ntawm lub molten aluminium. Lub tshuab nqus tsev yog tsim nyob rau hauv lub receiver tsim lub siab sib txawv ntawm qhov tuag kab noj hniav thiab molten aluminium nyob rau hauv lub crucible.
Lub siab sib txawv ua rau cov molten aluminium ntws mus rau hauv cov kab noj hniav tuag, qhov twg cov molten aluminium solidifies. Cov tuag raug tshem tawm ntawm lub receiver, qhib, thiab ib feem yog ejected.
Kev tswj lub tshuab nqus tsev thiab lub siab sib txawv ntawm qhov tuag kab noj hniav thiab molten aluminium ua rau nws muaj peev xwm tswj tau qhov sau tus nqi uas yuav tsum tau ua los ntawm ib feem tsim thiab cov kev cai gate. Kev tswj tus nqi sau ua kom muaj peev xwm los txiav txim siab lub suab ntawm qhov ua tiav.
Muaj cov sprue submerged hauv qab ntawm qhov saum npoo ntawm cov molten aluminium kom ntseeg tau tias cov molten aluminium yuav yog cov hlau tsis huv uas tsis muaj oxides thiab dross. Cov khoom yog huv si thiab suab nrog cov khoom txawv teb chaws tsawg tsawg.
5.Kev nqis peev Casting
Kev nqis peev casting, tseem hu ua poob ciab casting, pib nrog siv quav ciab raug txhaj rau hauv qhov tuag los tsim cov qauv ntawm cov khoom tiav. Cov qauv waxed yog txuas mus rau ib tug sprue los tsim ib tsob ntoo ike configuration. Cov ntoo yog dipped rau hauv slurry ntau zaus, uas ua rau lub plhaub muaj zog ceramic nyob ib ncig ntawm cov quav ciab.
Thaum cov ceramic tau teem thiab hardened, nws yog rhuab nyob rau hauv ib tug autoclave kom tiav cov dewax burnout. Txhawm rau ua kom tau raws li qhov xav tau ntawm lub plhaub, nws yog preheated ua ntej tau ntim nrog molten aluminium, uas yog poured rau hauv lub sprue thiab dhau los ntawm cov series ntawm runners thiab rooj vag rau hauv pwm. Thaum cov khoom ua kom tawv, cov ceramic yog khob tawm tawm ntawm cov ntoo txuas nrog cov khoom yuav raug txiav los ntawm tsob ntoo.
6. Poob Foam Casting
Cov txheej txheem ua npuas ncauj ploj yog lwm hom kev nqis peev casting qhov twg wax hloov nrog polystyrene ua npuas ncauj. Cov qauv yog molded los ntawm polystyrene nyob rau hauv ib pawg pawg zoo li tus khiav thiab sprues ntawm peev casting. Polystyrene hlaws yog txhaj rau hauv cov cua sov aluminium pwm ntawm qhov tsis tshua muaj siab nrog chav ntxiv kom nthuav cov polystyrene kom puv cov kab noj hniav.
Cov qauv yog muab tso rau hauv cov xuab zeb qhuav qhuav uas muaj kev vibration compacted kom tshem tawm cov voids lossis cov hnab ntim cua. Raws li cov molten aluminium yog poured rau hauv cov xuab zeb pwm, lub npuas yog hlawv tawm, thiab lub casting yog tsim.
Common Applications Of Casting Aluminium
Vim nws lub cev zoo thiab tshuaj lom neeg, ntau lub lag luam loj siv cam khwb cia txhuas. Nov yog ob peb yam kev siv ntawm cov khoom siv.
1. Kev lag luam kho mob
Kev kho mob ib feem manufacturers cia siab rau txhuas cam khwb cia rau lawv lub zog thiab lub teeb yuag nyob rau hauv ua prosthetics, phais trays, thiab lwm yam. Ib cag ntawm qhov ntawd, cov txheej txheem yog tsim rau kev ua complex thiab raug cov duab uas kev lag luam paub txog. Tsis tas li ntawd, txhuas yog cov khoom siv zoo vim nws qhov kev tiv thaiv corrosion vim muaj ntau yam khoom siv kho mob los ntawm kev sib cuag nrog cov kua hauv lub cev.
2. Automotive kev lag luam
Automotive qhov chaw manufacturers cia siab rau aluminium cam khwb cia rau lawv lub teeb yuag yam tsis muaj lub zog thiab durability. Yog li ntawd, nws tau txhim kho roj efficiency. Tsis tas li ntawd, ua cov khoom siv tsheb nrog cov duab nyuaj nrog cov txheej txheem aluminium casting yog yooj yim dua. Aluminium cam khwb cia yog tsim rau ua qhov chaw xws li brakes thiab kauj.
3. Kev lag luam ua noj
Cast aluminium yog qhov tseem ceeb hauv kev lag luam ua noj vim nws cov kav ntev, kev tiv thaiv corrosion, lub teeb yuag, thiab kev ua kom sov zoo heev. Ib cag ntawm qhov ntawd, cov khoom siv tsim nyog rau kev ua cookware vim nws cov cua sov zoo heev, piv txwv li, nws tuaj yeem ua kom sov thiab txias sai sai.
4. Kev lag luam dav hlau
Aluminium qhov chaw yog zoo meej rau kev lag luam dav hlau vim lawv lub teeb yuag thiab lub zog. Nws lub teeb yuag tso cai rau lub dav hlau siv roj tsawg los nqa hnyav dua.
