In contact with crucibles heated to very high temperatures (1500 \u00b0 C), the aluminum changes from a solid state to a gaseous state. Then it condenses on the film, which runs on two cooled drums (in order that the heat does not melt the flexible substrate).<\/p>\n

\nWhy vacuum metallization ?<\/strong><\/div>\n<\/div>\n

The metallisation is done under vacuum, because the temperature can be reduced to 1500 \u00b0 C, instead of 3000 \u00b0 C at normal atmospheric pressure. On the one hand, it is therefore an important energy saving. On the other hand it avoids oxidation of the aluminum and gives a bighter appearance to the product.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_single_image image=”14526″ img_size=”full” alignment=”center” style=”vc_box_shadow_3d” css=””][\/vc_column_inner][\/vc_row_inner][vc_single_image image=”14528″ img_size=”medium” alignment=”right” css=””][\/vc_column][\/vc_row][vc_row][vc_column][vc_separator][vc_single_image image=”12973″ img_size=”full” alignment=”center”][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
