Txhawm rau ua kom tau raws li cov kev xav tau sib txawv, cov ntawv hlau tuaj yeem ua tiav ntau yam thiab kev kho mob:
1. Txiav: suav nrog shearing, laser txiav, plasma txiav, thiab lwm yam, kom tau txais cov ntawv hlau ntawm ntau qhov sib txawv thiab cov duab.
2. Bending thiab Forming: Los ntawm cov txheej txheem xws li dabtsi yog khoov, stamping, thiab sib sib zog nqus daim duab, cov ntawv hlau yog ua tiav rau hauv ntau yam qauv.
3. Vuam: Siv los koom nrog cov ntawv hlau sib txawv los ua kom tiav cov qauv lossis cov khoom siv.
4. Kev kho deg: Txau, plating, polishing, etching, thiab lwm yam, txhawm rau txhim kho cov tsos zoo thiab corrosion kuj.
5. Kev kho cua sov: kho cov txheej txheem sab hauv ntawm cov hlau los txhim kho cov khoom siv kho tshuab.
