Qhov zoo thiab qhov tsis zoo ntawm Poob Foam Casting

Poob-ua npuas ncauj casting yog ib hom evaporative-pattern casting txheej txheem uas zoo ib yam li peev casting tsuas yog ua npuas ncauj yog siv rau cov qauv es tsis txhob siv quav ciab. Cov txheej txheem no yuav siv sij hawm kom zoo dua ntawm qhov tsis tshua muaj dej kub npau npau kom yooj yim rau kev nqis peev casting txheej txheem los ntawm kev tshem tawm qhov xav tau kom yaj cov quav ciab tawm ntawm pwm.
Qhov txheej txheem casting no yog qhov zoo rau cov txheej txheem nyuaj heev uas yuav xav tau cov cores. Nws kuj tseem muaj qhov tseeb qhov tseeb, tswj qhov zoo tshaj plaws nto tiav, yuav tsum tsis muaj cov cua ntsawj ntshab, thiab tsis muaj kab sib cais yog li tsis muaj flash tsim. Cov xuab zeb uas tsis muaj kev sib koom ua ke ntawm ploj ua npuas dej tuaj yeem ua tau yooj yim dua los tswj ntau dua li cov xuab zeb ntsuab thiab cov xuab zeb sib txuas ua ke. Poob ua npuas ncauj feem ntau yog kev lag luam ntau dua li kev nqis peev casting vim nws cuam tshuam cov kauj ruam tsawg dua. Risers feem ntau tsis tas yuav tsum tau ua vim qhov xwm txheej ntawm cov txheej txheem; vim hais tias cov hlau molten vaporizes ua npuas ncauj thawj cov hlau rau hauv pwm txias sai dua li lwm tus, uas ua rau lub ntuj directional solidification. Ua npuas ncauj yog yooj yim rau manipulate, carve thiab kua nplaum, vim nws cov khoom tshwj xeeb. Kev hloov pauv ntawm LFC feem ntau tso cai rau kev sib sau ua ke rau hauv ib qho tseem ceeb; lwm cov txheej txheem tsim yuav xav tau kev tsim khoom ntawm ib lossis ntau qhov chaw los ua ke.
Qhov tsis zoo ntawm ob lub ntsiab yog tias cov qauv nqi tuaj yeem siab rau cov ntawv thov ntim tsawg thiab cov qauv yooj yim puas los yog distorted vim lawv lub zog tsawg. Yog hais tias ib tug tuag yog siv los tsim cov qauv muaj ib tug loj pib nqi.
