Color Steel Insulated Sandwich Panel Production Line

The production line of color steel insulated sandwich panels adopts an integrated design of gas, electricity, and machinery, integrating systems such as unwinding, forming, composite, and cutting. The full process control is achieved through PLC and touch screen, supporting the switching of various core materials such as phenolic, mineral wool, glass wool, rock wool, polyurethane (PU/PIR), etc. Through modular combination, it can quickly adapt to different scene requirements such as roofs, walls, and cold storage.

Multi functional composite system

• Automation control: PLC and touch screen linkage control are adopted to achieve stepless speed regulation, fixed length cutting, and automatic counting functions. The production line is equipped with an integrated design of loading, unwinding, forming, compounding, and cutting.
  

• Modular design: Supports switching between various core materials such as rock wool and polyurethane (PU/PIR). The polyurethane production line can quickly switch to different products such as roof panels and cold storage panels by replacing modules.
  

• Energy saving technology: The energy consumption of the electric heating system is as low as 40% of the same type, and the environment above 5 ℃ can be heated to the process temperature within 1 hour without the need for additional insulation facilities.

Key process steps

• Composite process: High pressure foaming technology is used to bond the core material and color steel plate, with a glue amount of 0.25-0.4kg/㎡, combined with infrared heating curing to enhance the bonding strength.
  

• Diversified molding: It can produce H-shaped, plug-in, corrugated and other board types with a thickness range of 50-300mm. Some equipment can also process glass wool refractory boards.

No hydraulic servo lifting mechanism, dynamically adjustable plate thickness, fault self diagnosis system reduces downtime by 30%. The polyurethane production line supports double-sided color steel composite.

Application scenarios and selection suggestions

• Industrial buildings: Priority should be given to machines with high automation levels, and supporting molding machines can be used to expand the production of wall panels and roof panels.
  

• Cold chain logistics: It is necessary to match the polyurethane/PIR core material production line and design for low temperature stability at -30 ℃.
  

• Environmental requirements: The rock wool sandwich panel production line needs to be equipped with edge sealing and dust removal devices.
