Cov Txheej Txheem Casting: Kev Siv Tau Ntau Yam Los Ntawm Molding
Ibcam khwb cia hlau pob valveyog ua los ntawm kev nchuav cov hlau uas yaj rau hauv lub pwm uas tau ua tiav lawm. Cov hlau yuav khov thaum txias, zoo li lub cev valve, uas tom qab ntawd ntxuav thiab siv tshuab.
• Lub Ntsiab Cai Tseem Ceeb:Kev tsim ua kua ua rau muaj peev xwm tsim cov duab nyuaj heev thiab cov kab sab hauv hauv ib kauj ruam. Txawm li cas los xij, nws muaj kev pheej hmoo siab dua ntawm cov qhov tsis zoo xws li cov xuab zeb thiab cov pa roj porosity.
• Cov Kauj Ruam Ib Txwm Muaj:
1. Kev Tsim Pwm (piv txwv li, Pwm Xuab Zeb, Pwm Kev Nqis Peev)
2. Kev Yaj Hlau
3. Ncuav rau hauv pwm
4. Txias thiab khov kho
5. Tshem pwm thiab ntxuav (tshem cov rooj vag)
6. Kev Siv Tshuab
7. Kev Tshuaj Xyuas Zoo
Kev Ua Tau Zoo: Forged Steel Valve vs Cast Steel Valve
