Qhia txog cov txheej txheem tsim cov duab thav duab

Ua ntej, txiav: Siv lub tshuab txiav ua ntej txiav thiab shaping ntawm cov ntoo los yog txhuas phaj, thiab tom qab ntawd ua haujlwm ntxiv tom qab txiav.

Thib ob, stamping: Rau cov khoom siv txhuas, ib lossis ntau qhov kev kho mob stamping yog ua, thiab lub tshuab stamping yog siv rau kev ua kom tiav cov duab zoo tagnrho. Rau cov khoom ntoo, kev ua haujlwm ntxiv thiab polishing yog xav tau tom qab txiav los txhim kho cov khoom ntawm cov khoom.

Thib peb, txhob lo lo ntxhuav npo luam ntawv: Muab cov cim lag luam lossis cov lus tshaj tawm ntawm qhov pom tseeb tshaj plaws ntawm cov khoom kom ua tiav kev tshaj tawm thiab kev tshaj tawm zoo dua. Nyob rau tib lub sijhawm, nws tseem tuaj yeem tso cov cim lag luam tus kheej rau tus neeg siv khoom.

Plaub, ci xim: Siv cov thev naus laus zis no rau qee cov khoom lag luam los ua kom cov khoom sib txawv, kom cov nyhuv ntawm cov khoom ntau tshaj cov yam ntxwv ntawm ib qho khoom siv nws tus kheej, thiaj li ua tiav cov xim zoo nkauj thiab muaj txiaj ntsig zoo dua.

Thib tsib, kev sib dhos: Ntawm txoj kab sib dhos dynamic, ntau txhiab cov khoom sib dhos thiab tsim txhua hnub. Cov kev txawj ntse ntawm cov neeg ua haujlwm ua kom cov khoom zoo thaum sib dhos sai.

Thib rau, kev ntim khoom thiab kev tshuaj xyuas zoo: Lub ntim ntawm cov khoom yog nruj me ntsis raws li cov kev xav tau ntawm cov neeg siv khoom lossis kev coj ua thoob ntiaj teb, kom cov khoom tuaj yeem ua tiav cov txheej txheem xa tawm thiab tshuaj xyuas thiab cais tawm. Tom qab cov khoom tsim, txhua pawg ntawm cov khoom yuav raug soj ntsuam nruj kom ntseeg tau tias cov khoom muaj txiaj ntsig zoo los ntawm qhov chaw, lav zoo rau cov neeg yuav khoom thiab cov neeg siv khoom.
