Cov txheej txheem txias txias yog zoo li metamorphosis rau cov hlau, hloov pauv cov hlau zoo tib yam rau hauv ntau yam fasteners los ntawm precision yas deformation ntawm qhov kub thiab txias. Tag nrho cov txheej txheem suav nrog rau 6 cov kauj ruam intricate:
Kev Npaj Hlau: Xaiv cov hlau hlau ntawm txoj kab uas tsim nyog, ua kom lub ntsej muag huv si thiab tsis muaj oxidation.
Ncaj thiab Txiav: Tshem tawm khoov siv lub tshuab ncaj thiab txiav cov hlau kom meej rau qhov ntev.
Ua ntej-forming: Thaum xub thawj nias cov khoom rau hauv qhov khoob uas kwv yees qhov kawg ntawm cov duab.
Kev Tsim: Stamping ib feem hauv qhov tuag kom ua tiav nws cov duab kawg.
Punching thiab Trimming: Tshem tawm cov khoom siv ntau dhau thiab ua tiav qhov thiab cov npoo.
Kev Kho Hniav: Ua qhov tsim nyog tshaj tawm - ua, xws li polishing lossis plating.
