The Automatic PU Sandwich Panel Line usually consists of a series of automated equipment and systems, including but not limited to unwinding system, steel plate feeding system, steel plate automatic docking system, reinforcement unit, forming machine system, high-strength bonding system between steel plate and polyurethane, corona system, steel plate preheating system, double track machine and heating system, cutting system, packaging system, and conveying system. In addition, it may also include some auxiliary equipment, such as dust removal and environmental protection equipment, tank areas, and safety systems.

The working principle of the Automatic PU Sandwich Panel Line is relatively complex, but it can be roughly summarized as the following steps:

• Raw material preparation: prepare hard foam two-component raw materials (such as polyurethane stock solution) in a certain proportion.
  

• Mixing and pouring: The raw materials are sent to the mixing head by the metering pump of the high-pressure foaming machine for mixing, and then evenly poured onto the bottom surface material of the sandwich panel.
  

• Laminating and curing: the upper surface material and the poured foam raw material are sent to the double crawler laminating conveyor, foamed and solidified between the upper and lower chain plates of the conveyor.
  

• Cutting and packaging: The cured sandwich panel is cut into products of a certain length by a cutting machine on the production line as needed, and then packaged.

The products produced by the Automatic PU Sandwich Panel Line have various advantages, such as good insulation performance, flame retardancy, sound insulation performance, and environmental protection performance. These products are widely used in various fields such as construction, decoration, pipeline ventilation, subway construction, and cold chain building materials. Specifically, polyurethane sandwich panels can be used for external wall insulation in industrial plants, commercial office buildings, civil buildings, as well as for the production of cold storage panels, wall panels, roof panels, etc.

At present, the Automatic PU Sandwich Panel Line has a high demand and competitiveness in the market. With the continuous development of the construction industry and the increasing demand for energy conservation and environmental protection, the market demand for polyurethane sandwich panels, as an efficient and energy-saving building material, will continue to grow. Meanwhile, with the continuous advancement of technology and the improvement of automation level, the production efficiency and product quality of the Automatic PU Sandwich Panel Line will also be further improved.
