1, General qhov teeb meem ntawm precision casting

Precision casting yog lub ntsiab lus dav dav ntawm precision casting tshuab.Precision casting yog ib hom hlau tsim cov khoom tau los ntawm cov txheej txheem ntawm precision casting, uas yog, los ntawm pouring molten kua rau hauv lub npaj casting pwm los ntawm pouring, txhaj, inhalation los yog lwm txoj kev, thiab ces txias kom tau tej yam zoo li, loj thiab kev ua tau zoo. .

Precision casting suav nrog peev casting, ceramic casting, hlau casting, siab casting thiab poob ua npuas ncauj casting.Ntawm lawv, peev casting yog feem ntau siv, los yog siv quav ciab poob casting: xaiv cov ntaub ntawv tsim nyog peev (xws li paraffin) los ua peev pwm;rov ua cov txheej txheem refractory thiab xuab zeb blasting txheej txheem ntawm cov peev pwm, ua kom lub plhaub tawv thiab qhuav;thaum peev casting, siv cov txheej txheem kev kho cua sov.Thaum cov pwm sab hauv yog melted kom tau cov kab noj hniav;lub plhaub yog calcined kom tau txais lub zog txaus thiab hlawv tawm qhov seem.Cov khoom siv pwm;hlau cov ntaub ntawv rau pouring;solidification txias, shelling, xuab zeb tu, thiaj li yuav tau txais high-precision khoom.Raws li cov khoom xav tau lossis kev kho cua sov, kev kho mob txias thiab kev kho deg.
