Sheet hlau ua yog hais txog kev tsim cov khoom siv hlau los ntawm cov ntawv nyias nyias. Piv txwv li, nws tsim cov khoom xws li chimneys, hlau chim, roj tso tsheb hlau luam, roj cov kaus poom, qhov cua ducts, lub luj tshib, reducers, hloov daim, thiab funnels. Cov txheej txheem tseem ceeb suav nrog kev txiav, khoov, folding, sib sau, vuam, thiab riveting, uas yuav tsum muaj qee qhov kev paub txog geometric. Sheet hlau qhov chaw yog cov khoom siv hlau nyias uas tuaj yeem ua tiav los ntawm stamping, dabtsi yog khoov, thiab ncab. Ib qho kev txhais dav dav yog tias cov no yog cov khoom uas nws cov thickness tseem tsis hloov pauv thaum ua. Nyob rau hauv sib piv, lwm hom hlau Cheebtsam muaj xws li castings, forgings, thiab machined qhov chaw.
Kev ua haujlwm txias feem ntau yog hais txog kev txiav thiab shaping ntawm cov hlau, qhov twg cov cuab yeej txiav tshem tawm cov hlau ntau dhau los ntawm cov khoom ua haujlwm lossis qhov khoob kom ua tiav cov duab tshwj xeeb, qhov loj me, thiab qhov chaw tiav. Cov txheej txheem ua haujlwm txias xws li tig, drilling, milling, npaj, sib tsoo, thiab broaching. Hauv kev ua haujlwm hlau, kev ua haujlwm txias yog txhais raws li cov txheej txheem ua rau cov yas deformation hauv cov hlau hauv qab nws qhov kub thiab txias recrystallization. Qhov no suav nrog cov txheej txheem xws li txias dov, kos duab txias, txias forging, stamping, thiab txias extrusion. Kev ua haujlwm txias yuav ua rau muaj kev cuam tshuam ntau dua thiab tuaj yeem ua rau muaj zog thiab lub zog ntawm cov khoom siv los ntawm kev ua haujlwm hardening. Txawm li cas los xij, nws kuj txo cov hlau ductility. Kev ua haujlwm txias yog tsim rau kev tsim cov khoom hlau nrog me me ntoo khaub lig- ntu qhov ntev thiab qhov xav tau siab rau qhov raug qhov tseeb thiab qhov chaw tiav.
