Ua rau tuag taus.
1) cov khoom siv ntawm qhov chaw ua haujlwm tseem ceeb ntawm cov pwm tsis raug xaiv.Qhov khoom siv zoo, tsis muaj kev sib tw ua haujlwm; Cov pwm hlau tsis zoo, thiab muaj ntau yam tsis sib xws; Convex thiab concave tuag, forging txheej txheem tsis zoo meej , muaj cov kev kho mob thaum tshav kub kub.
2) qhov tsim cov qauv kev tuag tsis tsim nyog.Qhov elongated thiab convex pwm tsis yog tsim los txhawb cov cuab yeej, qhov chaw tawm qhov chaw tawm tsis tuaj yeem tshwm rau hauv pawg, thiab lub zog tawm ntawm kev lag luam tawm hauv kev nce ntawm kev hloov ntawm tus sawv cev lub rooj sib tham pauv.
3) txoj kev molding tsis zoo meej, feem ntau tshwm sim hauv qhov sib txawv ntawm qhov sib xyaw convex thiab concave tuag forging, kev kho cov tshuab tshav kub kub thiab cov txheej txheem muaj teeb meem, ua rau muaj convex, concave tuag quenching, muag pob thiab tsis sib luag. ntuag, sib tsoo thiab polishing yog tsis nyob rau hauv qhov chaw, qhov nqi roughness tus nqi loj heev.
4) tsis muaj lubrication lossis lubrication tab sis tsis zoo cov nyhuv.
