Continuous PIR Sandwich Panel Production Line

The continuous PIR sandwich panel production line adopts a modular assembly concept, and all components are completed through CNC machining centers, achieving rapid exchange and combination. It supports the production switching of various core materials such as PU, PIR, rock wool, etc., and the thickness can be adjusted.

Key technologies of continuous pir sandwich panel production line

• Double track laminating process
  High temperature foaming: In a constant temperature environment of 50-60 ℃, the spraying uniformity of the foaming material is controlled by PLC to ensure that the density deviation of the core material is ≤ 3%.
  Synchronous molding: The upper and lower color steel plates (thickness 0.4-1.2mm) are laminated with PIR core material in one go, and the line speed can reach 8-12m/min.
  Intelligent temperature control: The infrared temperature measurement system monitors the track temperature in real-time with an error of ± 1 ℃.

• Fully automatic cutting system
  High precision cutting: laser positioning combined with hydraulic cutting blade, length error ≤ 0.5mm/m, supports customized size (up to 24m).

• Polyurethane edge sealing technology
  Rock wool composite process: using PIR edge sealed rock wool sandwich panel, with improved fire resistance level, suitable for high demand scenarios such as purification workshops.
  Waterproof structure: The concealed nail connection is combined with a unique waterproof groove design, and the roof slope can be as low as 3%.

Expansion of application areas

• In the field of new energy: used for fire-resistant partitions in lithium battery factories, resistant to electrolyte corrosion.
  

• Cold chain logistics: The dimensional stability is better than EPS/XPS materials at -40 ℃ low temperature environment.
  

• Modular building: Eccentric hook plate design enables fast splicing, increasing construction efficiency by 40%.
