This production line adopts European technology, cost reduced by technical transformation, which has high stiffness, strength, accuracy, and stability; polyurethane sandwich panel production line is used for the continuous production of polyurethane foam sandwich panel, such as polyurethane insulation panel with surface layer of non-woven cloth, cement mortar, kraft paper or aluminum foil.
Working principle of pu sandwich panel production line:
Polyurethane resin, curing agent and foaming agent are delivered to high-speed mixing head in certain proportion through metering pump, evenly mixed and continuously coat an basal plate by coating head's reciprocating motion, then enter into double crawler machine with plate, foam and cure between the top and bottom layer of heated double crawler machine; when it is cured and shaped, the trimming device on both sides will get it into accurate size. Finally, the sizing following tracing cutting machine cut off it as per preset length.
