Ua ntej- kev kho mob theem: Cov hlau yuav tsum tau ua kom zoo dua cov hlau siv lead ua, pickling los tsim cov phosphate tiv thaiv zaj duab xis los tiv thaiv pwm khawb, thiab tom qab ntawd txias kos duab kom ua tau raws li cov txheej txheem ntawm txoj kab uas hla.
Kev tsim theem: Peb cov txheej txheem tseem ceeb tau ua tiav los ntawm kev siv ntau- chaw nres tsheb txias taub hau tshuab:
Txiav: Precisely tswj qhov khoob qhov ntev thiab lub ntsej muag kawg.
Thawj punch: Ua ntej-forging lub ntsiab lus ntawm lub taub hau.
Thib ob punch: Cov txheej txheem nyuaj xws li qhov kawg precision tsim ntawm tus ntoo khaub lig zawj yuav tsum tau siv kev sib cais pwm ua ke.
Tom qab-kev ua: suav nrog xov dov txoj kev, tempering kev kho cua sov (hardness control), thiab tiv thaiv nto electroplating. Cov txheej txheem xov dov yuav tsum tuav cov pwm ua haujlwm saum npoo roughness Tsawg dua lossis sib npaug rau Ra0.2μm.
