Punching ua yog ib txoj kev ua hlau uas ua haujlwm ntawm ntau yam ntaub ntawv, suav nrog carbon steel, galvanized steel, stainless hlau, txhuas thiab tooj liab. Cov ntaub ntawv no muaj lawv tus kheej cov yam ntxwv thiab qhov zoo hauv kev ua haujlwm stamping.

Ua ntej tshaj plaws, cov pa roj carbon steel yog cov khoom siv xuas nrig ntaus ua cov khoom siv nrog cov txheej txheem zoo thiab lub zog, thiab tsim nyog rau kev tsim ntau yam qauv thiab cov khoom. Galvanized steel muaj cov khoom tiv thaiv corrosion zoo heev thiab tsim nyog rau kev tsim cov khoom lag luam uas xav tau kev tiv thaiv corrosion, xws li cov khoom siv tsheb thiab cov khoom siv hauv tsev.

Stainless hlau muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, kub tsis kam thiab zoo nkauj tsos, thiab yog tsim rau kev tsim khoom siv hauv chav ua noj, tableware, architectural kho kom zoo nkauj thiab lwm yam khoom. Aluminium yog lub teeb yuag, muaj cov thermal conductivity zoo thiab cov khoom siv kho kom zoo, thiab tsim nyog rau kev tsim cov khoom siv aerospace, cov khoom siv tsheb thiab cov khoom siv hluav taws xob.

Tooj liab muaj cov hluav taws xob zoo thiab thermal conductivity thiab tsim nyog rau kev tsim khoom xws li cov khoom siv hluav taws xob, cov xov hlau, thiab cov hluav taws xob. Yog li ntawd, raws li kev xav tau ntawm cov khoom sib txawv thiab cov kev xav tau ntawm engineering, cov ntaub ntawv tsim nyog tuaj yeem raug xaiv rau kev xuas nrig ntaus ua kom tau raws li cov khoom lag luam thiab cov kev xav tau zoo. Hauv kev siv tswv yim, kev xaiv cov ntaub ntawv yuav tsum tau ua tib zoo xav txog yam xws li cov khoom siv lub zog, kev tiv thaiv corrosion, kev ua haujlwm, thiab tus nqi kom ntseeg tau tias cov khoom kawg muaj kev ua tau zoo thiab kev lag luam.
