qhov zoo dua
(1) Qhov ntau thiab tsawg ntawm cov stamping qhov chaw yog tau lees paub los ntawm cov pwm, uas muaj cov yam ntxwv zoo ib yam, yog li ntawd qhov zoo yog ruaj khov thiab qhov sib hloov ua tau zoo.
(2) Vim kev siv cov pwm ua, nws muaj peev xwm ua kom tau qhov chaw nrog cov phab ntsa nyias, lub teeb nyhav, kev coj zoo, qhov chaw zoo, thiab cov duab uas lwm txoj kev ua tsis tuaj yeem lossis nyuaj rau kev tsim khoom.
(3) Stamping processing feem ntau tsis tas yuav muaj cua sov ntawm seem, thiab nws tsis txiav ntau ntau ntawm cov hlau zoo li txiav kev, yog li nws tsis tsuas yog txuag hluav taws xob, tab sis kuj txuag tau hlau.
(4) Rau cov xovxwm uas ib txwm ua, nws tuaj yeem tsim tau ntau daim ntawm ib feeb, thaum lub tshuab nrawm nrawm nrawm tuaj yeem tsim ntau pua lossis ntau txhiab daim ib feeb. Li ntawd, nws yog tus txheej txheem zoo heev.
Vim tias cov txheej txheem stamping muaj cov yam ntxwv hais saum toj no, nws tau siv dav hauv ntau yam ntawm kev lag luam hauv lub teb chaws. Piv txwv li, kev lag luam xws li aerospace, tshuab, ntaub ntawv hluav taws xob, tsheb thauj mus los, riam phom, khoom siv hauv tsev, thiab kev lag luam teeb txhua qhov muaj stamping ua. Tsis tsuas yog nws siv dav hauv kev lag luam, tab sis txhua tus neeg muaj kev sib cuag ncaj qha nrog cov khoom stamping txhua hnub. Stamping tuaj yeem tsim qhov me me ntawm cov khoom me hauv moos thiab cov twj paj nruag, thiab ntxiv qhov npog loj rau cov tsheb thiab tsheb laij teb. Cov ntaub ntawv stamping tuaj yeem siv cov ntawv tsis muaj hlau, tsis muaj hlau thiab qee yam tsis siv hlau.
