Core Module

• Color steel plate feeding system
  Adopting a double coil unwinding device, automatic correction ensures precise alignment of the upper and lower metal plates (usually color steel plates, stainless steel or aluminum plates), providing a foundation for subsequent composite.

• Polyurethane high-pressure foaming machine
  By precisely controlling the mixing ratio of isocyanates and polyols, foam material is injected between bimetallic plates to form a uniform PU insulation layer. High pressure foaming technology can improve the density and closed cell ratio of foam and enhance the thermal insulation performance.

• Continuous laminating machine
  Adopting the double belt pressing process, PU is rapidly cured through heating (60-80 ℃) and pressure (0.5-1MPa), while achieving flatness and thickness control of the board (common thickness 50-200mm).

• Fixed length cutting system
  Equipped with servo driven flying saws or laser cutting devices, the error is controlled within ± 1mm and supports customization of multiple specifications.

• Stacking and packaging line
  Automated stacking robotic arm combined with PE film packaging enhances the efficiency of finished product protection.

Technical highlights and innovations

• Energy saving design: Some equipment integrates a heat recovery system, which uses laminated waste heat for preheating raw materials, reducing energy consumption by 15% -20%.
  

• Intelligent control: Adopting PLC+touch screen control system, real-time monitoring of foaming density, temperature, pressure and other parameters, automatic alarm for abnormalities.
  

• Modular configuration: The device supports quick mold replacement and can produce various board types such as corrugated and flat.
  

• Environmental compatibility: Compatible with environmentally friendly foaming agents such as cyclopentane.

Typical application scenarios

• Cold chain logistics
  Used for cold storage walls and ceilings, PU sandwich panels have low thermal conductivity and can save more than 30% energy compared to traditional materials.

• Industrial plant
  Combining lightweight and high strength, suitable for large-span buildings.

• Cleanroom
  The surface coated color steel plate can meet food grade antibacterial standards, and with seamless polyurethane bonding technology, it meets cleanliness requirements.

The PU sandwich panel forming equipment is a high-end production line that integrates automation control, high-pressure foaming, continuous forming and other technologies. It is mainly used for producing polyurethane (PU) sandwich panels and is widely used in building insulation, cold storage, purification workshops and other fields. The demand for PU sandwich panel equipment in the current market continues to grow, especially in the fields of cold chain logistics and green building. Investing in models with high automation and low energy consumption will become a trend.
