Two aluminium coils of the same width are unrolled, flattened and brushed simultaneously; on the lower strip, a circuit of channels is imprinted by means of a screen printing technology.\nThe two strips are heated to a temperature of about 400 \u00b0C in two continuous furnaces, and \nsubsequently coupled and hot rolled at a pressure of 600 tons.<\/p>\n<\/div>\n

Upon exiting the hot rolling mill, the two strips are perfectly joined together and, after an annealing phase at a temperature of roughly 450 \u00b0C, the strip is cooled, dried and cut into equal length plates. \nAn automatic press inflates the Roll-Bond panels on a production line, which are subsequently cut to size with automated cutting lines or laser cutting machines.<\/p>\n<\/div>\n
The complete production flexibility of Roll-Bond technology allows to create an unlimited number of ducts, making the cooling plates suitable for multiple applications.\n\nMainly used in the refrigeration sector, Roll-Bond technology was also recently extended to air conditioning, the automotive industry, renewable energy, electronics and many other sectors.<\/p>\n<\/div>\n
