High precision investment casting rau valve

Cov txheej txheem casting peev txheej muab cov khoom siv valve zoo tshaj plaws, sib txuas ua ke kev tsim kho kom raug nrog cov khoom siv zoo tshaj plaws. Cov txheej txheem poob-wax ua tiav qhov tseeb ntawm qhov ntev thiab qhov ua tiav ntawm qhov chaw zoo dua (Ra 3.2μm lossis zoo dua), txo qhov yuav tsum tau ua haujlwm thaum ua kom muaj cov qauv geometries nyuaj, phab ntsa nyias, thiab cov kev hla sab hauv nyuaj uas tsis tuaj yeem ua tiav los ntawm cov txheej txheem ib txwm muaj. Peb tshwj xeeb hauv ntau yam khoom siv suav nrog cov hlau tsis xeb, duplex / super duplex alloys, thiab cov superalloys ua tau zoo, txhua yam ua raws li ASTM, ASME, thiab API cov qauv. Cov txheej txheem tswj hwm solidification ua kom ntseeg tau tias cov qauv noob zoo tshaj plaws, txhim kho cov khoom siv kho tshuab rau kev ua tau zoo dua hauv qhov siab siab, kub siab, thiab corrosive ib puag ncig. Txoj hauv kev tsim khoom ze-net-puab no tsis tsuas yog txhim kho kev siv cov khoom siv tab sis kuj txo cov nqi tsim khoom thiab lub sijhawm ua khoom. Peb lub peev xwm ua haujlwm tas li ua kom ntseeg tau tias muaj qhov zoo rov ua dua rau ob qho tib si tus qauv thiab kev cai valve tsim, muab cov kev daws teeb meem tsim rau cov ntawv thov tswj dej uas xav tau tshaj plaws.
