Kev piav qhia
Cov Poob Wax Precision Casting Parts yog ua los ntawm 420 stainless hlau. 420 stainless hlau yog martensitic stainless hlau, uas muaj ib tug tej yam degree ntawm hnav tsis kam thiab corrosion kuj, thiab muaj ib tug siab hardness. Nws tus nqi yog ib chav kawm qis ntawm stainless hlau pob, thiab nws yog qhov tsim nyog rau kev ua haujlwm ib puag ncig uas tsis muaj kev xav tau siab rau stainless hlau. 420 stainless hlau yog tsim rau txhua yam ntawm precision machinery, bearings, hluav taws xob, khoom siv, twj, twj, tsheb thauj mus los, khoom siv hauv tsev, thiab lwm yam.
Fabrication method
Cov Poob Wax Precision Casting Parts no yog tsim los ntawm txoj kev poob ciab. Txoj kev no tsis tas yuav qhib pwm thaum ua cov pwm, yog li cov duab ntawm cov casting tsis tshua muaj kev txwv los ntawm cov txheej txheem. Qhov loj tshaj ntawm txoj kev no yog siv cov ntaub ntawv uas tsis tshua muaj melting point li "pwm", simplifying lub pwm ua txheej txheem. Txoj kev no tuaj yeem ua kom tiav cov khoom tiav yam tsis muaj vuam. Txoj kev no tuaj yeem ncaj qha nrum qhov tseeb heev, tsis tas siv cov khoom. Piv nrog rau cov pa turnover casting, nws yog qhov tsim nyog rau cov khoom siv casting nrog cov duab nyuaj.
