Cov khoom siv hlau hauv chaw ua haujlwm yog hais txog lub ntsiab lus dav dav rau ntau yam khoom siv hauv chaw ua haujlwm thiab cov khoom siv pabcuam siv hauv chaw ua haujlwm ib puag ncig, ua cov khoom siv hlau ua lawv cov qauv lossis cov khoom tseem ceeb, thiab ua tiav los ntawm cov txheej txheem xws li stamping, vuam, casting, khoov, thiab kho qhov chaw. Cov khoom no feem ntau yog siv cov hlau, aluminium alloys, stainless hlau, thiab lwm yam hlau ua cov ntaub ntawv hauv paus, hais txog kev ruaj ntseg thiab kev ua haujlwm zoo, feem ntau ua haujlwm rau cov kev xav tau yooj yim xws li kev tswj cov ntaub ntawv, cov ntaub ntawv khaws cia, chaw ua haujlwm, thiab kev txhawb nqa chaw ua haujlwm.
Los ntawm kev xav txog kev siv, cov khoom siv hlau hauv chaw ua haujlwm tsis txwv rau ib hom khoom siv tab sis suav nrog ntau yam khoom siv uas cuam tshuam nrog kev ua haujlwm hauv chaw ua haujlwm. Piv txwv muaj xws li cov ntaub ntawv hlau, cov ntaub ntawv khaws cia, cov phau ntawv, cov ntaub ntawv tuav, rooj thav duab, kev nyab xeeb, staplers, thiab ntau yam khoom siv hlau cia. Lawv cov yam ntxwv tseem ceeb nyob hauv lawv cov qauv hlau, muab kev thauj khoom- kabmob, kev tiv thaiv, thiab kev siv sijhawm ntev- lub sijhawm ua haujlwm, thaum tib lub sijhawm ua haujlwm raws li kev tsim kho vaj tse thiab cov cuab yeej hauv chaw ua haujlwm, ua rau lawv yog ib qho tseem ceeb ntawm cov chaw ua haujlwm niaj hnub no.
Los ntawm kev xav txog ciam teb, cov khoom siv hlau sib txawv ntawm cov khoom siv hauv chaw ua haujlwm ua los ntawm cov yas, ntoo, lossis lwm yam khoom siv feem ntau hauv lawv cov khoom siv thiab cov yam ntxwv ntawm cov qauv. Txawm li cas los xij, hauv kev siv tswv yim, lub tswv yim no muaj qee qhov sib tshooj. Piv txwv li, qee cov khoom siv tuaj yeem siv cov qauv sib xyaw nrog cov hlau, yas, ntoo, thiab lwm yam. Tsuav yog cov hlau ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa lossis kev ua haujlwm, lawv tseem tuaj yeem suav nrog hauv qeb ntawm cov khoom siv hlau. Nrog rau kev txhim kho ntawm chaw ua haujlwm ib puag ncig, lub tswv yim tseem txuas ntxiv mus tas li, maj mam txuas ntxiv los ntawm cov khoom siv ib txwm siv rau cov khoom siv hauv chaw ua haujlwm niaj hnub uas sib xyaw ua haujlwm, zoo nkauj, thiab kev txawj ntse.
