Hauv kev lag luam tsheb, cov khoom ntim khoom yog qhov haujlwm tseem ceeb heev. Ntau yam sib txawv ntawm cov khoom siv stamping tau siv hauv kev sib dhos lossis tsim cov tsheb loj. Cov ntaub ntawv raw siv hauv cov ntawv thooj ntawv no sib txawv, thiab ib puag ncig thiab lub hom phiaj ntawm kev siv kuj txawv. Tam sim no cia' saib cov hlau stamping qhov chaw.
Qhov chaw stamping hlau yog ib yam ntawm cov hlau stamping qhov chaw rau tsheb. Yam khoom thooj ntawv no muaj qhov sib txawv hauv ntim, qhov hnyav thiab siv ib puag ncig. Txawm li cas los xij, hauv kev tsim khoom thiab siv cov txheej txheem, hom khoom siv thooj ntawv no vam khom nws tus kheej tshwj xeeb, nyob hauv txoj haujlwm siab hauv kev ua cov khoom siv tsheb thooj av.
Ib qho ntxiv, hauv cov txheej txheem tsim khoom ntawm cov hlau stamping qhov chaw, raws li ib puag ncig thiab lub hom phiaj ntawm lawv siv, kev ua haujlwm sib txawv, tab sis feem ntau hais lus, pleev xim, electroplating lossis phosphating tiv thaiv kev kho yog hom kev kho mob ntau heev.
Feem ntau, cov khoom ntim hlau tuaj yeem tsim tawm hauv chav ib puag ncig kub thaum tsim khoom. Hom khoom siv stamping no feem ntau yog ua los ntawm cov hlau lossis cov hlau tsis yog hlau raws li cov khoom siv raw hauv kev tsim khoom, thiab hauv cov txheej txheem ntawm kev ua cov khoom thooj, Cov pwm siv kuj yog ua los ntawm cov khoom no. Los ntawm cov pwm ua ntej no, ua ke nrog kev ua haujlwm siab ntawm cov xovxwm, hom khoom siv thooj ntawv no tau tsim raws li qhov ua tiav.
Txawm hais tias muaj ntau hom sib txawv hauv cov txheej txheem ntawm kev ua lub tsheb thooj voos kheej kheej, xws li kev kho tshuab lossis ua yas, txheej txheem thev naus laus zis siv hauv cov txheej txheem ua cov hlau stamping feem ntau muaj qhov zoo ntawm kev lag luam thiab yooj yim ntawm kev ua haujlwm. Nta.
Ua ntej tshaj plaws, hauv cov txheej txheem ntawm kev ua cov hlau stamping qhov chaw, cov tswv lag luam tuaj yeem siv cov cuab yeej siv tshuab rau kev tsim khoom, lossis siv cov cuab yeej siv tshuab rau kev tsim khoom, thiaj li ua kom ntseeg tau tias cov khoom siv stamping tau tsim, cov khoom muaj ntau dua li tus qauv, thiab kev ua haujlwm tau zoo dua qub. Hauv kev tsim cov khoom thooj ntawv, cov xovxwm tuaj yeem tsim ib qho khoom lag luam hauv ib qho haujlwm, thiab thaum siv cov nias sib txawv, cov naj npawb ntawm cov khoom thooj ntawv uas tsim tawm rau ib lub sijhawm sib txawv. Cov xovxwm zoo ib yam tuaj yeem tsim kaum ob ntawm qhov chaw thim nyiaj hauv ib feeb, tab sis kev nrawm nrawm nrog kev ua tau zoo tuaj yeem tsim tau ntau pua qhov chaw thim ib feeb.
Cov pwm siv hauv cov txheej txheem ua cov hlau thooj ntawv yog ua los ntawm cov ntaub ntawv zoo, yog li nws tuaj yeem ua kom ntseeg tau tias lub neej ntawm pwm tuaj yeem siv tau ntev dua. Cov pwm no muaj kev txwv nruj me ntsis, qhov loj me, qhov ntxhib nto thiab lwm yam ntxwv hauv kev tsim khoom. Yog li ntawd, hauv cov txheej txheem ntawm kev ua qhov chaw thim nyiaj, nws tuaj yeem ua kom paub meej tias cov txheej txheem stamping tau tsim nyob rau hauv nruj raws li qhov ntsuas, thiab cov nplais ntawm qhov chaw thooj ntawv tuaj yeem ua kom ntseeg tau. Nws yuav tsis raug puas tsuaj. Ib qho ntxiv, kev tsim khoom tam sim no siv rau hauv pwm, thiab nws yooj yim los hloov txhua qhov kev tiv thaiv tom qab nws puas lawm.
Ib qho ntxiv, thaum siv cov pwm los ua cov hlau stamping qhov chaw, tsuav yog cov yam ntxwv ntawm cov pwm tau teev tseg, cov khoom thooj ntawv uas tsim tau tuaj yeem lav kom ua tau raws li qhov xav tau. Yog li ntawd, thaum cov neeg ua haujlwm tsim ntau yam ntawm cov khoom siv thooj ntawv, txawm tias cov khoom siv thwj rau hauv lub npog ntawm lub tsheb lossis lub sijhawm nres hauv lub moos, kev siv cov pwm tshwj xeeb tuaj yeem ua tiav cov khoom ruaj khov. Tsis tas li ntawd, cov ntaub ntawv siv hauv qhov chaw thwj cim yog txias. Kev hloov pauv thiab ua kom tawv tuaj yeem ua kom ntseeg tau tias cov khoom siv thooj ntawv muaj lub zog siab thiab cov qauv nruj.
