Insulation PU Sandwich Panel Production Line

The insulation pu sandwich panel production line is a system that uses automatic equipment to realize the composite processing of color steel plate and polyurethane foam. It is compatible with color steel/aluminum foil/cement based cloth, and can produce polyurethane, rock wool, mineral wool, glass wool, phenolic and other types of panels

sandwich panel line

The insulation polyurethane sandwich panel line can be divided into two types according to the production mode: continuous and discontinuous. The core equipment includes:

• Uncoiling and Forming System
  The fully automatic unwinding machine is equipped with a hydraulic correction device, which can process steel coils with a width of 800-1250mm and a forming speed of up to 15m/min (continuous). The non continuous type adopts a molding machine, and the length of the single board can reach 12 meters.
  The upper and lower steel plates are processed into the desired plate shape through roll forming equipment, and the quick replacement mechanism supports diversified designs (such as corrugated, flat, etc.).

• Foaming and laminating system
  The high-pressure foaming machine adopts six component online mixing technology (continuous) or two-component infusion (discontinuous), with a ratio accuracy of ± 0.5% and a foaming density deviation controlled within ± 5%.
  The temperature control range of the double track laminating machine is 40-120 ℃, the pressure is 2kg/cm ², and the curing time is shortened by more than 30%.

• Post processing and automation control
  The follow-up saw cutting machine achieves a cutting accuracy of ± 1mm, and the palletizing system automatically stacks. The daily production can reach 300 square meters (non continuous) or 2000 square meters (continuous).
  Siemens PLC integrated control system realizes real-time parameter monitoring and supports remote fault diagnosis.

Process flow: Five stage continuous production (uncoiling → forming → pouring → foaming → cutting → palletizing), using six component online mixed casting technology.

Sinowa insulation pu sandwich panel production line supports quick switching between PU/PIR/rock wool core materials, and the surface layer is compatible with materials such as color steel, aluminum foil, non-woven fabric, etc., suitable for multiple scenarios such as cold storage, factory buildings, and exterior walls.

Application in the field of architecture: steel structure factory buildings, cold chain logistics warehouses, prefabricated building exterior wall insulation.
