Punching kev ua yog ib txoj kev sib koom tes hlau uas ua haujlwm ntawm ntau cov ntaub ntawv, suav nrog cov roj carbon hlau, suav nrog cov hlau roj carbon monoxide, galvanized steel, stainless hlau, txhuas thiab tooj. Cov ntaub ntawv no muaj lawv tus cwj pwm thiab cov txiaj ntsig zoo hauv kev ua stampinging.

Ua ntej tshaj plaws, carbon steel yog ib feem siv punching ua cov txheej txheem zoo thiab lub zog, thiab haum rau kev tsim khoom ntau yam qauv thiab cov khoom siv. Galvanized steel muaj cov tshuaj tiv thaiv zoo heev thiab yog qhov tsim nyog rau kev tsim cov khoom lag luam uas yuav tsum tau corrosion tsis kam, xws li cov khoom siv hluav taws xob thiab cov cuab yeej cuab cov cuab yeej cuab tam.

Stainless hlau muaj cov yam ntxwv ntawm corrosion tsis kam, muaj qhov kub zoo thiab zoo nkauj, thiab kho kom zoo nkauj thiab lwm yam khoom. Aluminium yog lub teeb yuag, muaj qhov zoo thermal conductivity thiab zoo chaw kho cov khoom, thiab qhov chaw tsheb thiab khoom siv hluav taws xob.

Tooj liab muaj cov hluav taws xob zoo thiab thermal ua haujlwm thiab yog qhov tsim nyog rau kev tsim khoom xws li cov hluav taws xob sib txuas, cov xov hlau, thiab cov tshuab hluav taws xob, thiab khoom siv hluav taws xob, thiab cov tshuab hluav taws xob, thiab khoom siv hluav taws xob, thiab cov tshuab hluav taws xob, thiab khoom siv hluav taws xob, thiab cov tshuab hluav taws xob, thiab khoom siv hluav taws xob, thiab cov tshuab hluav taws xob, thiab cov raj hlav hluav taws xob, thiab cov raj hlav hluav taws xob, thiab khoom siv hluav taws xob, thiab cov tshuab hluav taws xob, thiab khoom siv hluav taws xob. Yog li ntawd, raws li cov khoom lag luam sib txawv thiab cov khoom tsim muaj, cov ntaub ntawv uas tsim nyog tuaj yeem xaiv rau kev siv cov khoom lag luam thiab cov khoom ua tau zoo. Hauv kev siv cov kev siv, cov ntaub ntawv xaiv yuav tsum muaj kev nkag siab zoo xws li cov khoom siv cov khoom siv cov khoom siv zaum kawg muaj kev ua tau zoo thiab kev lag luam zoo.
