Rihont injection PU panel In order to obtain a perfect and homogenous adhesion between the polyurethane and the pre-painted galvanized steel sheet the polyurethane injection and expansion is effected in hot press.
Raw materials of rigid-foam liquids are delivered into the mixing head through the metering pump on the injection machine and then injected onto the bottom facing sheet going to conveyors along with the top superficial sheet. Between the upper and lower conveyors, the liquid materials are foamed and hardened into shape, after which the laminated panel is edge-trimmed and cut by an automatic tracking cutter into segments according to the preset length.
