This line is for making PE/B1 class aluminum composite panel. Thebasic theory is to composite aluminum coil, high polymer film andcore material from extruder under the pressure of high temperaturerollers, and cut it to the required length. We upgraded the 2nd,3rd ,4th generation line referred to the advantages of the 1stgeneration lines from Germany, and invented 2-roller compositing,3&2-roller two-way compositing technique. Not only improved theoperation and use performance, but also regarded as the originalproductions in the industry.
