Product Details product description
PU sandwich panel production line is used for continuous production of sandwich panels, double side is flexible material with polyurethane or Phenolic inside . The main products of this line are exterior wall insulation composite panel and duct of central air-conditioner. It’s working principle is : four component of regid foaming material according to a certain ratio deliveried to mixing head by metering pump of high pressure foaming machine, and distributed even on the bottom sheet of lower sandwich panel, deliveried with upper coil to the double belt laminating conveyor at the same time. Regid foam blowed and solidified to shape during the upper and lower conveying chain plate. The shapped sandwich panel cut to a certain prodution desired length products by cutting machine on produciton line.
