Cold forming yog ib txoj kev ua ntawm txhuas ntawv ci, qhov paub zoo tshaj plaws yog txias ua aluminium foil. Cov khoom siv txhuas uas twb muaj lawm nyob rau hauv cov txheej txheem ntawm ntau yog siv los ua kom tiav qhov tsim ntawm cov tshuab tuag casting, txias nws yog multilayer composite cov ntaub ntawv, aluminium, nylon, aluminium, PVC) muab cov khoom tso rau hauv ib puag ncig kub, siv cov stamping tuag ib tug npaum li cas ntawm lub siab nyob rau hauv lub siab ntawm daim ntawv, pab kom nws tsim cov yas deformation lossis sib cais, xav tau cov khoom zoo thiab qhov loj me, Xws li cov txheej txheem siab molding. Hauv cov txheej txheem txias txias, aluminium ntawv ci yog molded los ntawm pwm nyob rau hauv siab los tsim ib kab noj hniav. Vim li no, txias txoj kev yog kim tshaj li kub sib sau.

Cov kev taw qhia ntawm hlau ntws txawv raws li extrusion. Cov txheej txheem tuag casting tuaj yeem muab faib ua rau pem hauv ntej extrusion, rov qab extrusion thiab ua ke extrusion. Cov kev taw qhia ntawm extrusion axis ntawm pem hauv ntej extrusion yog zoo ib yam nrog cov ntws kev taw qhia ntawm cov hlau extruded, thaum lub ndlwg kev taw qhia ntawm thim rov qab extrusion yog opposite. Thiab txias forming aluminium foil yog hu ua ntau extrusion cua sov kub los faib. Extrusion tuaj yeem muab faib ua kub extrusion thiab txias extrusion, kub extrusion yog lub ingot yog rhuab rau recrystallization kub saum extrusion, thiab txias extrusion yog extrusion ntawm chav tsev kub, uas kuj yog lub hauv paus ntawm lub npe ntawm txias forming aluminium ntawv ci.

Cold-formed foils feem ntau ntim rau hauv cov ntawv ci tag nrho raws li cov khoom xav tau kev tiv thaiv siab tshaj plaws. Hauv qee lub tebchaws tsim kho nyob rau sab hnub poob, kev siv cov tshuaj yeeb dej caw yog nce ntxiv nrog rau kev siv cov ntawv txias txias. Cold-formed aluminium foil tseem tau txais koob meej ntxiv, raws li nws tsuas yog cov khoom uas yog 100 feem pua ​​resistant rau noo noo, oxygen thiab lub teeb.

Aluminium foil / aluminium foil blister ntim yog cov khoom sib xyaw, ib tug ntawm cov uas muaj ib tug laminated yas zaj duab xis (PVC los yog PE), txheej txheej yog feem ntau yog cov nplaum, ntawv ci, nplaum, thiab cov yas zaj duab xis sab nrauv. Cov txheej txheej sab nraud ntawm aluminium ntawv ci, uas tau PET los yog PVC, txhawb nqa nyias aluminium ntawv ci thiab ua raws li thermal foob. Cov txheej txheem ntau txheej no pab xyuas kom cov pinholes tsis dhau los ntawm cov ntawv ci, xyuas kom nruj. Nws kuj muaj qee yam hlau stretching peev xwm, txhawb txoj kev kos duab txias. Cov daim hlau multilayer no yog tsim, ntim thiab kaw rau ntawm lub tshuab uas ua cov haujlwm no hauv cov txheej txheem tsim khoom ua ntej, ib yam li cov thermoplastic-filling-sealing tshuab ua, yam tsis muaj daim hlau hlwv raug rhuab ua ntej cov kauj ruam molding.

Hauv cov txheej txheem txias txias, cov kab noj hniav yuav tsum loj dua nyob rau hauv cov txheej txheem kub txheej txheem, uas tsub kom tag nrho cheeb tsam ntawm lub pob, thiab cov khoom tseem tuaj yeem txav mus rau hauv npuas.
