Polyurethane pu continuous 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.

Automatic control of pu sandwich panel production line:
Automatic control system includes uncoil area control, double crawler forming machine and drying cutting area control, the whole control system is operated through touch screen parameter and s to realize automation production with reliable and stable preformance, simple and easy opeartion, Each operating position is installed with emergency stop to ensure equipment and personal safety in case of an emergency, The adopting of new technology realizes high accuracy, high intelligence, and high speed control.
