PU Rockwool Sandwich Panel Production Line is a continuous automatic composite production equipment for PU edge-sealed rockwool sandwich panels. It integrates upper and lower steel facings, rockwool core and PU foam material through continuous pouring, edge sealing, double-belt pressing & curing, fixed-length cutting and finished panel conveying. The finished panels feature excellent fire resistance, thermal insulation and structural rigidity. With high automation and stable process, the line delivers panels with good sealing performance and high fire rating. It is widely used in industrial workshops, clean rooms, cold storage and prefabricated buildings. The whole layout can be customized according to workshop dimensions, compatible with different panel thicknesses and joint profiles.
