A sandwich panel production line is always required for the production of metal skinned, Eps/xps board or Rockwool and Glass mineral wool insulated roofing and wall panels of prefab buildings, like assembled container houses.
People like to use metal roofing and wall panels made of pre-painted steel coils or galvanized steel coils instead of stones, bricks or clay tiles for most of residential, commercial, industrial and agricultural steel buildings, however a single metal roofing or wall panel is not a thermal sheet which can prevent a building or a house getting too hot in summer or too cold in winter.
An Eps and Rockwool insulated sandwich panel machine line has been designed for the continuous production of metal faced roofing and wall sandwich panels with thermal materials insulated mainly used for the building of prefab houses. The metal skins for roofing sandwich panels are trapezoildal roofing sheets made of pre-painted steel coils with thickness 0.3-0.8mm, width 1250mm maximum; the thermal materials for roofing and wall sandwich panels are usually EPS or XPS board, and Rockwool or Glass mineral wool;
EPS/Rockwool sandwich panel production line generally consists of 3 manual decoiler, a roof or wal panel roll forming machine (double layer roll forming machine will be equipped for the production of two types of roof sandwich panels), a feeding table for EPS or XPS board and Rockwool or Glass mineral wool strips, glue mixing system, pressing or composing machine, a tracking fly-saw cutter, run-out table and control system. Optional equipment will be provided as per requests, such as auto stacking machine,and auto packing machine.
