Nquag porosity, txias kaw, thiab deformation nyob rau hauv tuag- nrum qhov chaw? Cov lus piav qhia ntxaws txog cov teeb meem tseem ceeb ua rau thiab cov txheej txheem optimization daws teeb meem.

Nyob rau hauv lub loj ntau lawm ntawmaluminium tuag castingthiabzinc tuag casting, tsis xws luag xws li porosity, shrinkage kab noj hniav, txias kaw, ntws cov cim, cov khoom warping, thiab ntug burrs tau ntev plagued loj manufacturers. Cov khoom lag luam tsis zoo tsis tsuas yog nce cov khoom pov tseg thiab cov nqi rov ua dua tshiab tab sis kuj tseem ncua kev xa khoom xa tuaj, cuam tshuam rau lub sijhawm ntev - kev koom tes ntawm cov neeg muag khoom thiab cov neeg siv khoom. Especially for high-end components in new energy, 3C electronics, and precision instruments, where stringent requirements exist for internal density, appearance, and dimensional tolerances, defect control has become a key indicator of atuag casting tsob nroj's core kev sib tw.
Porosity thiab shrinkage kab noj hniav yog cov feem ntau tsis xws luag nyob rau hauv tuag casting. Tsis tiav degassing thaum lub sij hawm raw khoom melting, tsis txaus pwm venting tsim, ntau yam fluctuations nyob rau hauv pouring kub, thiab tsis zoo sib xws ntawm filling speeds yuav tag nrho cov ua rau gas trapping nyob rau hauv lub molten hlau, tsim porosity. Lub caij no, cov kev hloov pauv tseem ceeb hauv cov khoom phab ntsa tuab, qhov tsis sib xws ntawm lub tshuab cua txias, thiab cov khoom tsis sib haum xeeb tuaj yeem ua rau cov kab noj hniav tsis zoo. Lub hom phiaj kev txhim kho feem ntau suav nrog kev ua kom sov thiab ziab ntawm cov khoom siv raw, kev ua kom zoo ntawm cov pwm venting qauv, segmented hloov ntawm kev txhaj tshuaj, thiab sib npaug pwm txias dej channel tsim, txo qhov kev faib ua feem ntawm qhov tsis xws luag los ntawm molding qhov chaw.
Nyias-cov khoom siv plhaub phab ntsa yog qhov ua rau txias kaw, uas yog qhov tseem ceeb los ntawm qhov kub thiab txias ntawm qhov sib xyaw ntawm ob lub molten hlau, uas ua rau tsis muaj fusion. Cov tsos mob zoo li no tuaj yeem txhim kho tau zoo los ntawm kev tsim cov pwm preheating kub, optimizing lub rooj vag layout, thiab shortening lub sij hawm filling. Cov teeb meem xws li warping, demolding khawb, thiab ntau burrs tom qab tuag casting feem ntau yog vim tsis muaj DFM tshuaj xyuas ntawm qhov pib kos duab, tsis tsim nyog lub kaum sab xis teeb tsa, thiab tsis txaus parting nto txuam qhov raug. Cov kws tshaj lijtuag casting tuam txhab uas muagyuav cuam tshuam rau hauv cov qauv kev ua kom zoo thaum ntxov hauv cov txheej txheem qhib pwm, txuam nrog lub kaum sab xis tsim nyog, thiab koom tes nrog cov txheej txheem tom ntej tsis siv neeg ntug trimming kom ruaj khov khoom seem sib xws.
Tam sim no, kev sib tw hauv kev lag luam tuag casting yog maj mam hloov los ntawm qis- tus nqi sib tw rau kev tswj kom zoo. Kev txheeb xyuas qhov tsis xws luag thiab kev txhim kho muaj peev xwm tuaj yeem txo cov nqi txuas ntxiv thiab nce kev ua haujlwm zoo rau cov neeg siv khoom qis. Peb lub tuam txhab lees paub kev caituag casting lag luamrau aluminium alloys thiab zinc alloys xyoo- puag ncig. Peb pab pawg kws tshaj lij tuaj yeem muab cov phiaj xwm kho tshwj xeeb rau cov neeg siv khoom kuaj thiab cov khoom lag luam tsis zoo, thiab muab ib qho dawb - nres cov kev pabcuam suav nrog kev twv ua ntej txheej txheem, kev sim ntsuas kev tsim khoom, thiab kev tswj hwm ntau lawm. Cov neeg muas zaub nrog kos duab prototyping thiab loj ntau lawm xav tau txais tos hu rau peb.
