Yenziwa ngokungeza ungqimba lwe-foil yensimbi esisekelweni sefilimu ngokusebenzisa i-coating kanye ne-vacuum evaporation. Ugqinsi lwe-aluminium anodized ngokuvamile (12, 16, 18, 20) μ m. Ububanzi obungu-500 ~ 1500mm. Ucwecwe lokugxiviza olushisayo lwenziwa ngelendlalelo yokukhululwa enamathelayo, isendlalelo sombala, i-vacuum aluminium bese imboza ifilimu kufilimu, futhi ekugcineni ibuyisela emuva umkhiqizo oqediwe.
