Kev siv xuab zeb casting yuav ntsib cov teeb meem hauv qab no hauv kev xyaum, thiab cov kev daws teeb meem sib xws:
1. Cov pwm xuab zeb tawg lossis hloov pauv: cov pwm xuab zeb yuav raug cuam tshuam los ntawm qhov kub thiab txias siab thaum lub sijhawm nchuav, ua rau tawg lossis hloov pauv. Cov kev daws teeb meem suav nrog kev siv cov khoom xuab zeb muaj zog siab, ntxiv cov khoom siv lossis cov qauv txhawb nqa kom txhim kho kev tiv taus cua sov ntawm cov xuab zeb.
2. Qhov thiab qhov tsis zoo: thaum lub sijhawm ua xuab zeb casting, vim tias cov pa roj nyuaj rau khiav tawm ntawm cov xuab zeb, nws yuav ua rau muaj qhov lossis qhov tsis zoo sab hauv ntawm qhov chaw ntawm qhov casting. Cov kev daws teeb meem suav nrog kev ua kom zoo dua cov qauv xuab zeb, txhim kho kev tsim qauv ntawm lub kaw lus casting, thiab ntxiv cov qhov cua kom txhawb kev khiav tawm ntawm cov pa roj thiab txo qhov tshwm sim ntawm qhov tsis zoo.
3. Qhov loj ntawm kev casting tsis yog qhov tseeb: kev casting xuab zeb, vim yog qhov shrinkage thiab deformation ntawm qhov casting, tej zaum yuav ua rau qhov loj ntawm casting tsis yog qhov tseeb. Cov kev daws teeb meem suav nrog kev tswj qhov nrawm ntawm cov pwm xuab zeb los ntawm kev kho qhov loj ntawm cov pwm thiab kev them nyiaj shrinkage tsim nyog kom ntseeg tau tias qhov casting kawg mus txog qhov loj me tsim nyog.
4. Kev lag luam hnyav thiab cov khoom pov tseg ntau: Vim tias lub neej ua haujlwm ntawm cov pwm xuab zeb tsawg, tej zaum yuav xav tau kev lag luam hnyav thiab kev kho, ua rau muaj cov khoom pov tseg ntau hauv cov txheej txheem tsim khoom. Cov kev daws teeb meem suav nrog kev ua kom zoo dua qub ntawm kev tsim pwm xuab zeb, siv cov ntaub ntawv pwm xuab zeb uas tiv taus cua sov zoo dua, txhawb kev saib xyuas pwm xuab zeb, thiab lwm yam, kom ntev lub neej ua haujlwm ntawm cov pwm xuab zeb thiab txo cov khoom pov tseg.
Cov qauv yav tom ntej ntawm kev lag luam xuab zeb casting yuav suav nrog cov hauv qab no:
1. Kev siv tshuab thiab kev txawj ntse: nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, kev ua xuab zeb yuav qhia ntau yam kev siv tshuab thiab thev naus laus zis ntse los txhim kho kev ua haujlwm zoo thiab zoo.
2. Kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob: txo cov khib nyiab thiab kev siv hluav taws xob hauv cov txheej txheem ntawm kev npaj xuab zeb, thiab txhawb kev txhim kho ntawm kev lag luam xuab zeb casting mus rau kev coj ntawm kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob.
3. Zoo thiab raug siab: los ntawm kev ua kom zoo dua cov ntaub ntawv thiab cov txheej txheem xuab zeb molding, qhov zoo thiab raug ntawm cov castings tau txhim kho tas li kom tau raws li qhov kev thov ntawm kev ua lag luam rau cov khoom.
4. Kev tsim khoom sai thiab kev hloov kho kom haum: qhia txog kev siv tshuab prototyping sai thiab kev tsim khoom raws li qhov xav tau kom luv lub voj voog tsim khoom thiab muab cov kev daws teeb meem khoom lag luam raws li tus kheej.
5. Kev tsim kho tshiab ntawm cov khoom siv thiab kev nthuav dav ntawm daim ntawv thov: tshawb nrhiav kev siv cov khoom siv tshiab hauv kev xuab zeb casting, thiab qhib kev lag luam dav dua.
Qhov saum toj no tsuas yog ib qho ntawm cov kev taw qhia kev loj hlob ntawm kev lag luam xuab zeb casting yav tom ntej. Nrog rau kev txhim kho tas mus li ntawm thev naus laus zis thiab kev hloov pauv ntawm kev thov ua lag luam, kev lag luam xuab zeb casting muaj ntau lub peev xwm thiab cov cib fim.
