This line is divided into 3 sections - forming section, injecting section and run-out section. Forming Section is to shape the uncoiled skins. In Injection Section, a machine injects Polyurethane on the pre-heated skins and when the skins are passing through the double slat conveyor, the Polyurethane is foamed to a complete panel. After that it is cut into required length. The Run-out section transfers the complete panel and turns over for the packing. The whole line is operated automatically and saves labour work.
