Phab ntsa thickness yuav tsum yog nruab nrab thiab sib xws, thiab qhov tsim nyog demoulding lub kaum sab xis yuav tsum tau tshwj tseg. Txwv tsis pub, yuav muaj dents, xuab zeb qhov, shrinkage qhov, unformed stretch marks, kab nrib pleb, dabtsi yog khoov thiab lwm yam teeb meem nyob rau hauv lub castings, uas ua rau ib tug loj tus naj npawb ntawm cov hlau castings tsis tsim nyog.
2. Pwm tsim, raug raug thiab pwm cov ntaub ntawv thov
Castings yog cam khwb cia nrog cov khoom siv pwm, uas yog ze rau qhov zoo. Tsis muaj teeb meem dab tsi tawm tsam yog coj los ntawm kev siv thev naus laus zis, kev tsim pwm yog qhov tsis raug. Tsis muaj txoj hauv kev kom tsim nyog cov khoom.
3. Cov ntaub ntawv nyoos txo tus nqi
Thaum txo tus nqi ntawm tus thawj cov ntaub ntawv ntawm stainless hlau castings feem ntau yog muab nyob rau hauv daim ntawv ntawm ib tug dav feem pua los yog feem pua, thiab muaj ib tug sib xws ntau yam ntawm variation. Tus nqi luv luv ntawm cov ntaub ntawv qub feem ntau yog siv, thiab cov cuab yeej siv pwm tuaj yeem ua tiav yog tias tsim nyog.
4. Kev tsim thiab kev siv tshuab casting
Kev tsim thiab kev siv cov txheej txheem casting yog ze ze rau cov khoom pwm, cov khoom zoo ntawm cov cuab yeej casting thiab cov txheej txheem ntawm cov neeg ua haujlwm tiag.
