Cov pwm mus tas li yog hais txog cov txheej txheem casting uas siv cov pwm tshwj xeeb (tuag) kom tau txais cov kua nplaum cam khwb cia hlau. Nws yog tsim los tsimcastingsnyob rau hauv qhov ntau. Cov txheej txheem cating no yog hu ua hlau tuag casting lossis lub ntiajteb txawj nqus tuag casting, txij li cov hlau nkag mus rau hauv pwm hauv lub ntiajteb txawj nqus.
Piv nrog rau cov xuab zeb casting, plhaub pwm casting los yog peev casting, nyob rau hauv uas pwm yuav tsum tau npaj rau txhua yam ntawm cov casting, cov pwm mus tas li tuaj yeem tsim cov castings nrog tib lub tshuab molding rau txhua qhov casting.
Cov khoom siv pwm ntawm qhov chaw mus tas li yog txiav txim siab los ntawm kev txiav txim siab ntawm qhov kub thiab txias, qhov loj ntawm qhov casting thiab zaus ntawm lub voj voog casting. Lawv txiav txim siab tag nrho cov cua sov yuav tsum tau yug los ntawm qhov tuag. Fine-grained grey cam khwb cia hlau yog feem ntau siv cov khoom siv tuag. Alloy cam khwb cia hlau, carbon steel thiab alloy steels (H11 thiab H14) kuj yog siv rau cov ntim loj heev thiab qhov loj. Graphite pwm tuaj yeem siv rau cov ntim me me los ntawm txhuas thiab magnesium. Lub neej tuag yog tsawg dua rau qhov kub siab melting alloys xws li tooj liab lossis grey cam khwb cia hlau.
Rau kev ua ib qho hollow feem, cores kuj yog siv rau hauv cov pwm mus tas li. Cov cores tuaj yeem ua los ntawm hlau lossis xuab zeb. Thaum siv cov xuab zeb cores, cov txheej txheem hu ua semi-permanent molding. Tsis tas li ntawd, cov tub ntxhais hlau yuav tsum tau muab tshem tawm tam sim tom qab solidification; txwv tsis pub, nws extraction yuav nyuaj vim shrinkage. Rau cov duab nyuaj, collapsible hlau cores (ntau daim cores) yog qee zaum siv cov pwm mus tas li. Lawv siv tsis yog qhov dav vim qhov tseeb tias nws yog qhov nyuaj rau kev ruaj ntseg ntawm qhov tseem ceeb raws li ib qho ntawm ib qho raws li qhov sib txawv ntawm qhov sib txawv uas yuav tshwm sim. Yog li ntawd, nrog collapsible cores, tus tsim qauv yuav tsum muab siab ntev rau ntawm qhov ntev.
Nyob rau hauv lub voj voog casting tsis tu ncua, qhov kub ntawm cov pwm siv yog nyob ntawm qhov kub thiab txias, casting voj voog zaus, casting hnyav, casting zoo, casting phab ntsa thickness, phab ntsa thickness ntawm pwm thiab thickness ntawm pwm txheej. Yog hais tias lub casting yog ua tiav nrog lub txias tuag, thawj ob peb castings yuav muaj misruns mus txog rau lub tuag mus txog nws cov hauj lwm kub. Txhawm rau zam qhov no, cov pwm yuav tsum tau pre-rhuab rau nws qhov kev ua haujlwm kub, nyiam dua hauv qhov cub.
Cov ntaub ntawv uas feem ntau cam khwb cia rau hauv pwm mus tas li yog aluminium alloys, magnesium alloys, tooj liab alloys, zinc alloys thiab grey cam khwb cia hlau. Chav tsev casting hnyav li ntawm ob peb grams mus rau 15 kg nyob rau hauv feem ntau ntawm cov ntaub ntawv. Tab sis, nyob rau hauv cov ntaub ntawv ntawm txhuas, loj castings nrog ib tug loj ntawm txog 350 kg los yog ntau tshaj yuav raug tsim. Pwm tas mus li casting yog tshwj xeeb tshaj yog haum rau siab ntim ntau lawm ntawm me me, yooj yim castings nrog uniform phab ntsa thickness thiab tsis muaj intricate lug.
Qhov zoo ntawm Permanent Pwm Casting Txheej Txheem:
1. Vim hais tias ntawm cov hlau pwm siv, qhov txheej txheem no ua kom zoo-grained casting nrog superior mechanical zog.
2. Lawv tsim tau zoo heev nto tiav ntawm qhov kev txiav txim ntawm 4 microns thiab zoo dua tsos
3. Tight dimensional tolerances tau
4. Nws yog kev lag luam loj rau kev tsim khoom loj vim tias cov neeg ua haujlwm koom nrog hauv kev npaj pwm raug txo
5. Cov qhov me me-cored tej zaum yuav raug tsim los piv rau cov xuab zeb casting
6. Cov ntawv ntxig tuaj yeem muab pov rau hauv qhov chaw
