Stamping yog cov txheej txheem tsim khoom uas siv rau cov khoom siv sab nraud- xws li cov ntawv, strips, raj, thiab cov ntaub ntawv- siv cov xovxwm thiab cov tuag los ua kom cov yas deformation lossis sib cais, yog li tsim cov khoom ua haujlwm (stampings) ntawm cov duab thiab qhov ntev. Cov ntaub ntawv tseem ceeb rau stamping yog kub- dov thiab txias- cov nplooj ntawv steel thiab strips.
Cov ntaub ntawv rau stamping tuaj nyob rau hauv ntau yam ntaub ntawv, xws li nplooj ntawv, strips, thiab blanks (blocks). Cov ntawv loj loj thiab feem ntau yog siv rau stamping qhov loj; rau me me mus rau nruab nrab- qhov loj me, cov ntawv feem ntau yog txiav rau hauv ib daim hlab ua ntej siv. Strips (tseem hu ua coils) muaj nyob rau hauv ntau qhov dav thiab tuaj yeem ncav cuag ob peb mais ntawm qhov ntev, ua rau lawv haum rau kev pub mis tsis siv neeg hauv siab - ntim ntau lawm; cov ntaub ntawv nyias nyias kuj tuaj yeem muab rau hauv daim ntawv strip. Cov khoob tsuas yog siv rau stamping qib steel lossis kim tsis yog -ferrous hlau.
