The PU sandwich panel made of upper and bottom both metal steel panel and inject the PU liquid inside of them then after curing and then extrusion.
Superior Polyurethane adhesive property can make whole block between foam and metal panel and not need other material to stick again.
The metal panels can be extruded to various shapes and assure high stiffness and capacity
Introduction of production line
The PU continuous production line composed of un-coiler, Cut off the docking, filming, rib/forming, preheating, foaming, continuous solidify, cutting, stacking and packing etc. with high Automation and stable performance.
Foaming area composed of High pressure PU foaming machine , casting machine and double crawler etc.PU provided foaming machine with electrical metering mechanism, automatic coil provided system to insure the material mixed according to ratio, spraying equally, the double crawler with accurate temperature control system and safety foaming processing to assure foaming equally and stable.
