Nyob rau hauv cov txheej txheem ntawm cov khoom seem, muaj ntau ntawm kev siv tshuab yog cov txheej txheem ntau dua.

Cov txheej txheem stamping yog hais txog kev yoog raws ntawm stamping qhov chaw rau cov khoom siv tes, uas yog, tsim cov ntawv stamping hauv qhov loj me, qhov ntev thiab qhov raug ntsuas, qauv qauv thiab hais txog seb puas ua tau raws li cov txheej txheem thev naus laus zis ntawm stamping ua. Cov tsheb sib tsoo lub cev yuav tsum muaj tus cwj pwm zoo hauv kev lag luam thiab kev khwv nyiaj txiag, thiab cov cim tseem ceeb los ntsuas lawv qib yog tus naj npawb ntawm cov khoom stamping, cov naj npawb thiab qhov loj ntawm lub cev sib dhos, cov qauv ntawm cov khoom sib txawv thiab lwm yam.

Txo cov txheej txheem stamping cov txheej txheem, txhais tau hais tias tus lej stamping, txuag tus lej naj npawb, yooj yim cov txheej txheem ntawm kev xa khoom, txo cov neeg ua haujlwm thiab stamping thaj chaw, yog qhov kev ntsuas zoo kom txuag tau peev thiab siv zog, yog li cov stamping manufacturers tuaj yeem tso tus naj npawb ntawm stamping cov txheej txheem tsim raws li txoj hauv kev tseem ceeb los txo tus nqi tsim tsheb, txawm tias txhim kho cov khoom tsim los ua kom tau raws li cov kev xav tau ntawm kev tsim khoom.

Nyob rau tib lub sijhawm, tseem yuav tsum siv ntau li ntau tau qhov tsim nyog lub cev sib dhos, xws li tag nrho lub cev sab laug thiab sab xis phaj thiab vov npog phaj, tsis tuaj yeem tsuas ua rau lub tsheb zoo nkauj. Txo cov huab cua tsis kam, thiab txo tus naj npawb ntawm stamping qhov chaw thiab solder pob qij txha, tuaj yeem txo tus nqi. Thiab cov tsheb niaj hnub tsim USES cov khoom siv coil, cov plhaub nyias hom tag nrho lub cev qauv siab muaj zog lub zog steel phaj thiab galvanized steel phaj, txhua qhov kev thov thov siv cov ntawv thev naus laus zis tshiab.
