Tam sim no, cam khwb cia dov txheej txheem siv rau txhuas ntawv ci blanks yog maj mam maturing, thiab ntau thiab ntau lub lag luam tau pib siv cov txheej txheem cam khwb cia dov los tsim txhuas ntawv ci, thiab cam khwb cia dov tau dhau los ua cov txheej txheem tseem ceeb ntawm cov ntawv txhuas. Cam khwb cia dov tau tshwm sim hauv xyoo 1970, thiab cov cuab yeej siv tseem tsis zoo tag nrho.
Nyob rau hauv xyoo tas los no, GNEE Cov Khoom Siv tau tsim nws tus kheej tsim "casting thiab dov - txias dov luv luv txheej txheem ntsuab tsim tshuab", uas tau ua tiav rau cov khoom siv high-end xws li ob-zero foil thiab fais fab roj teeb ntawv ci. Cov cuab yeej siv los ntawm kev ua kom zoo tshaj plaws, txheej txheem melting, nruam casting thiab dov txheej txheem thiab txias dov / ntawv ci dov txheej txheem txheej txheem kev ua kom zoo, nrog rau kev ntsuas kev ua tau zoo, kev tswj hwm thev naus laus zis rau tag nrho kev lag luam saw innovation, kev siv casting thiab dov txoj kev hloov. ntawm cov txheej txheem kub dov los tsim cov ntawv txhuas txhuas / ntawv rau cov roj teeb hluav taws xob, txo cov nqi tsim khoom ntawm txhuas ntawv ci / ntawv rau cov roj teeb fais fab, txhim kho kev sib tw ntawm kev ua lag luam, thiab kom muaj kev loj hlob los txhawb kev txhim kho cov roj teeb txhuas hauv kev lag luam. Tuam Tshoj. Kev loj hlob.
Tom qab ua rau hauv cov ntawv txhuas ntawv ci, cov ntawv ci ntawv yog dov los ntawm cov txheej txheem ntawm roughing, nruab nrab thiab tiav yob los tsim aluminium foils ntawm txawv thicknesses, thiab ces annealed rau cov khoom tiav. Feem ntau hais lus, cov ntawv tuab tsuas yog yuav tsum tau ua cov ntawv ntxhib, ib leeg-xoom foils yuav tsum tau ntxhib dov thiab nruab nrab dov, thiab ob-zero foils thiab lwm yam aluminium foils nrog cov kev xav tau siab dua yuav tsum tau ua ntxhib dov, nruab nrab dov thiab tiav dov.
