Kev taw qhia txog kev ua haujlwm hlau rau tim Nkij teb chaws thaum xyoo pua 10th BC pib lub Hnub Nyoog Hlau hauv Tebchaws Europe. Cov neeg Greek thaum ub tau tsim cov cuab yeej cuab tam thiab riam phom los ntawm hammering hlau, txawm li cas los xij, Roman faj tim teb chaws tau nce mining rau hlau thiab pib tsim cov diav, saucepans, qhov rooj fittings thiab lwm yam khoom uas tseem siv cov ntawv hlau niaj hnub no.
(1) Ua ntej xyoo pua 20th
Txoj kev loj hlob ntawm cov ntawv hlau tshuab muaj keeb kwm ntev. Ntau txoj kev tau siv los smelt hlau los ntawm ancient bronze thiab hlau hlab ntsha. Nrog rau kev nce qib ntawm smelting technology, cov ntaub ntawv ntawm cov hlau phaj maj mam yaj, thiab kawm paub siv qee cov cuab yeej los daws cov ntaub ntawv ntawm cov hlau phaj. Qhov no yog tus qauv ntawm cov ntawv hlau tshuab. Ua ntej xyoo pua 20th, nws feem ntau yog xuas tes ua ntawv hlau.
(2) Txij li thaum ntxov 1980s
Lub Hoobkas ua cov ntawv hlau tau hais rau peb tias txij li thaum pib ntawm lub xyoo pua 20th, cov pwm thiab cov khoom siv stamping tau maj mam siv rau hauv kev ua cov ntawv hlau. Nyob rau xyoo 1980, CNC sheet hlau pib tshwm. Nyob rau hauv ib txwm muaj xwm txheej, kev txhim kho ntawm kev siv dav siv tuag thiab cov khoom siv stamping thiab CNC automation cov cuab yeej siv hlau nplaum muaj ob qhov tseem ceeb. Tus qub tau yug los rau stamping, thaum tom kawg tau yug los rau CNC sheet hlau.
(3) 20th Century Gift hauv 1980
Vim tias nyob rau xyoo 1980, Tuam Tshoj tau dhau los ua lub ntiaj teb kev tsim khoom thiab kev noj haus. Raws li lub hauv paus ntawm kev tsim khoom, ib qho ntawm cov stamping thiab sheet hlau kev lag luam kuj tau ua tiav qhov kev loj hlob tsis tau muaj dua. Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis hauv Suav teb, ntau cov ntawv hlau ua lag luam thiab kev lag luam tau pib tsim, piv txwv li, muab kev taw qhia laser rau kev lag luam zoo tsim ntawm cov ntawv hlau ua hauv Suav teb.
Sheet hlau ua Hoobkas tau hais rau peb tias vim tias nws tau siv dav hauv cov khoom siv hlau, suav nrog yuav luag txhua qhov kev tsim khoom thiab cov khoom siv raw, nws tsuas yog siv hauv kev sib txuas lus thiab kev lag luam hluav taws xob, tsheb, maus taus tsim, aerospace, ntsuas thiab ntsuas kev lag luam, tsev neeg. Cov khoom siv hauv kev lag luam, thiab lwm yam. Feem ntau, stamping thiab tsim ntawm txhua yam khoom siv tshuab thiab hluav taws xob yog siv rau kev tsim cov ntawv hlau, tsim rau batch ntau lawm stamping txheej txheem, thiab precision machining ntawm CNC sheet hlau ua.
