Kev nqis peev casting, tseem hu ua poob-wax casting, yog txheej txheem rau kev tsim cov khoom siv hlau thiab precision hlau castings siv fusible wax qauv. Nws cov kauj ruam yooj yim suav nrog ua tus qauv siv quav ciab, txheej nrog ntau txheej ntawm cov khoom siv refractory los ua lub plhaub, dewaxing los ua cov kab noj hniav, thiab tom qab ntawd tua thiab nchuav rau hauv cov hlau molten.
Cov thev naus laus zis no tuaj yeem taug qab rov qab mus rau txoj kev incineration siv nyob rau hauv nruab nrab -Shang Dynasty. Cov neeg laus laus ploj lawm- cov khoom siv quav ciab tau tshwm sim thaum lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg, xws li huab - qauv bronze nkoj tau pom hauv Xichuan, Henan. Niaj hnub nimno peev casting tshuab pib siv nyob rau hauv industrial ntau lawm nyob rau hauv lub 1940s. Cov txheej txheem no tsim cov castings nrog qhov siab qhov tseeb thiab qhov zoo ntawm qhov tiav, thiab tuaj yeem tsim nyob ze -net-puab qhov chaw nrog cov duab nyuaj thiab ntau yam khoom siv alloy. Nws yog dav siv hauv aerospace, automotive, thiab cov cuab yeej kho mob kev lag luam. Nyob rau hauv 2024, Suav peev casting lag luam loj yog 23.231 billion yuan.
