Thermal Insulation Sandwich Panel Production Line

The insulation sandwich panel production line is a high-end manufacturing system that integrates automation control, material composite, and precision molding. It mainly produces composite panels with core materials such as polyurethane (PU/PIR), phenolic (PF), and rock wool.

sandwich panel line

The core equipment includes:

• Raw material processing system: pre mixing device, foaming machine (for polyurethane core materials), mortar mixer (for cement-based boards).
  

• Molding module:
  Continuous laminating machine: The composite of color steel/aluminum foil and core material is achieved through rolling or hydraulic forming.
  Steel wire mesh welding machine (optional): enhances the bending strength of the plate, suitable for building load-bearing structures.
  

• Curing unit: Steam curing room or infrared heating system to accelerate the curing of core materials.
  

• Post processing equipment: fully automatic trimming machine, CNC cutting machine (accuracy ± 0.5mm), polyurethane edge sealing device (to improve fire resistance).

Innovative processes and product advantages

• Multi core material compatible design:
  Modular production lines can quickly switch between producing polyurethane, rock wool, or phenolic sandwich panels, such as Sinowa's PU/PIR/rock wool multi-purpose production line.
  The phenolic production line supports the composite of aluminum foil/non-woven fabric and other surface layers, with a closed cell rate of>95% and a thermal conductivity as low as 0.06W/m · K.

• Energy saving and environmental protection features:
  The cement foam insulation board production line utilizes industrial waste such as fly ash, with a daily output of 300m ³ and no wastewater or exhaust emissions.
  Polyurethane thread adopts pentane foaming technology to replace traditional fluorine, with zero ODP value.

• Intelligent control:
  The PLC+bus control system enables remote interaction, with a fault self diagnosis rate of over 90%.
  The automatic thickness adjustment system (servo lifting mechanism) replaces hydraulic control and improves accuracy by 30%.

In the field of architecture:

• Exterior wall insulation: A-level fireproof phenolic board is suitable for high-rise buildings.
  

• Cold storage/purification workshop: Polyurethane sandwich panels are preferred due to their low thermal conductivity.
