The line is a kind of specialized equipment used for producing color-steel-sided sandwich panels with the middle layer of anti-combustion polyurethane, polyisocyanurate or phenolic foam. The thickness of the produced sandwich panel ranges from 30 to 150 mm, the width between 700 and 1000 mm and the length on request. The production line is mainly applied to make wall and roof panels of steel structure buildings, which can also make various other insulation panels if replacing facing sheet. Its operation principle is as follows: Rigid polyfoam raw materials, according to a certain blending ratio, are delivered into mixing head to agitate through metering pump unit on the injection machine and then uniformly injected onto the bottom facing sheet of sandwich panel. After the injection, the bottom facing sheet shall move toward the double-belt conveyors together with panel’s top facing sheet. Between the two conveyors, injected raw material is foamed and hardened into shape. At the end of the line, the formed sandwich panel is cut into preset length by an automatic tracking cutter.
