The PUR Sandwich Panel Line usually consists of multiple key equipment, including uncoiler, forming machine, PUR spraying machine, high-pressure foaming machine, laminating machine, cutting machine, etc. These devices work together to complete the entire production process from raw material uncoiling, forming, spraying, foaming, compounding to cutting.

Working Principle

• Uncoiling and Forming: After the steel coil is unfolded on the unwinding machine, it enters the forming machine for compression forming, forming the bottom and upper surface materials of the sandwich panel.
  

• PUR spraying and foaming: the PUR foam plastic original solution is sent to the mixing head by the metering pump of the spraying machine in a certain proportion for mixing, and then evenly sprayed on the underlying surface material of the sandwich panel. Then, the upper surface material and the bottom surface material are sent together to the high-pressure foaming machine for foaming to form a sandwich layer of foam structure.
  

• Compounding and curing: the foamed sandwich board enters the laminating machine, and the upper and lower layers of surface materials are tightly combined with the foam sandwich layer through pressing. After that, the sandwich panel will be cured on the production line for a certain period of time to ensure that the foam is fully cured.
  

• Cutting and Finished Products: The cured sandwich panel is cut into a certain length of finished product by a cutting machine on the production line according to production needs. During the cutting process, customized sizes and shapes can be made according to customer requirements.

Characteristics and Application

• Highly automated: The PUR sandwich panel automatic production line integrates multiple processes such as unwinding, cutting and docking, laminating, spraying, foaming, laminating, and cutting, achieving highly automated production and greatly improving production efficiency.
  

• Stable quality: Due to the advanced technology and equipment used in the continuous production line of PUR sandwich panels, the quality of the sandwich panels can be ensured to be stable and reliable, meeting various application needs.
  

• Widely used: PUR sandwich panels have excellent insulation, heat insulation, sound insulation and other properties, and are widely used in the construction industry for walls, roofs, cold storage and other fields. Meanwhile, in the field of automobile manufacturing, PUR sandwich panels are also used to produce large quantities of panels such as body panels and interior panels.

With the continuous advancement of technology and the expansion of application scope, the continuous PUR sandwich panel production line is developing towards a more efficient, environmentally friendly, and intelligent direction.

The continuous PUR sandwich panel production line is an efficient and automated production equipment with broad application prospects and development potential.
