PU sandwich panel is the new wall building materials which have the best function of heat preservation, heat insulation, sound insulation, fire retardant, water proof, portable, environmental protection etc. It can be widely used in the external wall of retaining and decoration of high-rise building and senior office building The PU sandwich panel is the new wall building material for retaining, decoration and heat preservation. It is the most popular of new generation of decorative wall retaining timber construction. The product of this line—PU sandwich panel, is produced with foaming at working site. There’s device which can inject the foaming material between the upper and lower metal sheet ,then will be sent into double belt and evenly forwarded. The chemosynthesis and solidification are finished inside of double belt. The cutting is finished according to the length which is set before running the machine, it is non-stop cutting type, and the cutter will be moved along with the panel.
