Kev lag luam Casting cov ntaub ntawv siv quav ciab muaj tas li tshiab, txhawb kev txhim kho ntawm kev tsim kho kom haum.
Tsis ntev los no, nrog rau kev nce qib ntawm kev tsim khoom lag luam rau qhov zoo thiab ntau lawm kev ua haujlwm ntawm precisation wranting wranting wranting wranting wex tau siv nyob rau hauv ntau cov kev tsim kho tshiab. Peev Casting yog kev nce qib nyob ze ntawm cov khoom moulding, thiab kev ua tau zoo ntawm cov khoom siv quav ciab yog ncaj qha rau qhov tseeb, qhov chaw zoo thiab ntau lawm ruaj khov ntawm cov chaw pov tseg. Tam sim no, sib txawv ntawm cov peev txheej kev nqis peev yog ua kom nrawm nroos tshaj plaws hauv kev ua haujlwm ntawm kev ua haujlwm siab, ib puag ncig kev tiv thaiv thiab kev kho kom zoo.
Tam sim no muaj ntau yam peev xwm peev txheej los xaiv los ntawm. Hom ciab feem ntau yog nyob ntawm ntau yam ntawm factionity, seb lub ciab muaj peev xwm rov qab siv dua tshiab, qhov ntev sib xws, thiab ua tiav. Cov hauv qab no yog ntau hom waxes, suav nrog cov qauv sau siv ciab, khiav ciab, dej-soluble ciab thiab nplaum ciab.
Sau cov qauv ciab
Sau cov qauv ciab yog ib hom kev nqis peev casting siv quav ciab nrog ntxiv rau kev siv. Cov fillers no tuaj yeem muab qee cov khoom rau cov khoom siv kom ntseeg tau tias lawv lub zog, seem ruaj khov, qis qis qhov chaw nthuav dav thiab tsawg kawg nkaus shrinkage. Cov hom ntawm cov lim ntim uas tau siv hauv cov qauv siv viser los ntawm cov neeg xa khoom, tab sis qee cov fillsol), cov organic fillers, TereFhalic acid, thiab hla-txuas polystyrene txuas.
Sau cov qauv waxes tuaj yeem siv rau ob qho tib si me me thiab loj dua ciab txawv ntau lawm. Ob qhov zoo ntawm cov waxes no yog lawv qhov kev nthuav dav tsawg thermal thiab tsawg kawg nkaus shrinkage. Lawv tsis tas yuav tau muab cov ntaub ntawv txias ua ke kom muab tso rau hauv cov qauv kab noj hniav kom tiv thaiv shrinkage raws li cov ciab solidifies.
Hom ciab no feem ntau siv thaum koj xav tau qhov nrawm dua los yog sib dhos tsim thiab yuav tsum tau siv ntau yam ntawm kev txhaj tshuaj kub. Vim yog qhov sib ntxiv ntawm cov foob pob, qee cov ciab yuav nyob hauv cov plhaub ceramic tom qab cov txheej txheem Dewaxing vim tias cov ciab siv tau hlawv tawm. Txoj kev rov qab thiab rov siv cov qauv tsim qauv waxes yuav sib txawv raws li qhov ntom ntawm cov tub lim cov khoom siv.
Unfilled wax qauv
Cov qauv ciab tsis muaj txiaj ntsig, lossis tsis ua haujlwm me me hloov cov khoom sib xyaw, muaj cov khoom siv metter tsawg dua. Cov qauv ciab no muaj cov neeg siv tshuab ruaj khov thiab cov cua sov. Lawv feem ntau yog siv rau me me rau nruab nrab cov qauv ciab-qhov me me nrog cov kab ke ua kom zoo nkauj thiab cov kab ke zoo. Cov qauv ciab tsis muaj txiaj ntsig tau muaj cov khoom ntws tau zoo heev.
Lub ntsiab kom zoo dua ntawm cov qauv wax me me yog lawv qhov chaw siab zoo. Raws li qhov tshwm sim, cov ceramic pwm muaj cov kab nrib tawg tsawg dua thiab tsis xws luag. Ib qho ntxiv, nws tuaj yeem ua tiav tag nrho ntawm cov ceramic plhaub rau kev rov ua dua tshiab.
Kev saib xyuas yuav tsum tau ua thaum siv cov qauv ciab uas tsis tau ua tiav hauv kev nqis peev casting txheej txheem. Vim tias qeeb qeeb solidification, saum npoo ntawm cov qauv yuav xaws. Tsis tas li ntawd, nyob ntawm qhov ntsuas kub ntawm cov qauv ciab, cov ntoo khaub lig ntawm cov qauv yuav ua rau tsis muaj quav. Nyob ntawm ib feem configuration, weev txawv txawv coolant tej zaum yuav tsim nyog kom zam cov khoom shrinkage.
Khiav Wax Qauv
Peev Casting tuam txhab uas siv cov neeg khiav ciab Txawv sib xyaw thaum cov neeg ua haujlwm siab dua thiab qis dua viscosity yog qhov yuav tsum tau ua. Cov ciab no muaj qhov muag qis dua li cov qauv ciab. Yog li ntawd, thaum lub sij hawm dewaxing txheej txheem, lub ciab ntws tawm tag nrho ntawm cov ceramic pwm tsis tas yuav tsum siv qhov kub siab dua.
Qhov zoo ntawm kev khiav ciab yog nws zoo weld lub zog thiab tsawg kawg thermal nthuav tawm coefficiention. Cov neeg ua haujlwm tuaj yeem ua cov ciab tsis muaj kev txhawj xeeb txog qhov sib tsoo hauv cov ceramic pwm. Cov qauv ciab wax yuav tsum tau muab raus dej rau hauv dej thiab khaws cia kom txog thaum nws ua tiav.
Dej-soluble ciab
Qee qhov chaw thiab cov khoom siv yuav tsum muaj cov nyom thiab precise inductions. Yog li ntawd, cov cores meej yuav tsum tau teeb tsa sab hauv cov qauv ciab me. Txhawm rau tsim cov cores, dej-soluble ciab yuav tsum tau. Thaum cov tub ntxhais ua tiav tiav, nws tau muab tso rau hauv cov ciab pwm, thiab tom qab ntawd tus qauv ciab yog txhaj rau cov pwm. Thaum cov ciab mould txias, cov qauv yog muab tso rau hauv dej thiab acid da dej kom yaj cov dej-soluble tub sab hauv lub ciab mould.
Nplaum quav ciab
Npluav ciab feem ntau siv nyob rau hauv kev teeb tsa thiab ua tiav cov txheej txheem. Cov tshuaj haaxes no pab tau rau tus qauv sib txawv ua ke, lossis yog siv los sib dhos lub rooj vag. Cov quav ciab pab los tsim kev sib raug zoo nrog rau cov chaw, tso cai rau lawv nrog cov haujlwm ntawm cov neeg ua haujlwm thaum ua cov khauj khaum ceramic.
Saib mus rau yav tom ntej, kev nqis peev casting cov ntaub ntawv ciab tseem yuav txuas ntxiv mus rau hauv cov khoom lag luam ntsuab kom ua rau kev ua haujlwm zoo rau kev ua haujlwm kom ua tau zoo.
