Characteristics of the Polyurethane Sandwich Panel Production Line

The complete set of equipment for the polyurethane sandwich panel production line mainly consists of a decoiling system, film covering and cutting system, forming machine system, steel plate preheating furnace, high-pressure foaming system, double conveyor system, double conveyor heating system, cutting system, horizontal cooling system, stacking system, packaging system, and a series of other equipment. The core part of the polyurethane sandwich panel production line is the forming machine system.

Production Methods of Polyurethane Sandwich Panel

There are basically two production methods for polyurethane sandwich panels: continuous production and discontinuous production. Currently, the continuous production process is suitable for companies that have high yield requirements, whereas the discontinuous production process is suitable for producing special shaped products that cannot be produced continuously, or for production volumes that do not justify investing in continuous equipment.

In the continuous production process, the materials for making the sandwich panel are processed together at high speed. Polyurethane foam is continuously sprayed between the uniformly moving forming upper and lower surface materials, where it undergoes a polymerization reaction to form polyurethane sandwich panels of different forms. The cutting of the fully formed sandwich panel is dne according to the desired length, and the production line does not stop during the cutting process.

In the discontinuous production process, the materials are processed separately. This means that after the surface material is formed, it is cut to the required length, then assembled together and sent into the laminating machine, where foam is injected between the surface materials to form polyurethane sandwich panel in pre-set shapes.

Features of Polyurethane Sandwich Panel Production Line

• The width of the wall panel type can be adjusted to suit different wall width requirements.

  
  

• The adjustable wall panel frame is welded with integrated profiles, the roller shafts on both sides adopt a cantilever structure, single-row bearing seats adopt a combined method to ensure the precision and rigidity of the bearing seats, and the single-row bearing seats are mounted on a ball guide rail. Adjustments can be easily made by adjusting the screw rod to change specifications.

  
  

• The roller wheels and shafts of the forming machine are made of high-quality carbon structural steel, tempered, CNC fine processed, and surface plated with hard chrome, which ensures excellent overall structural performance, thereby ensuring the panel's stability, flatness, and normal forming process.

  
  

• The bearing seats of the roof panel forming machine adopt an independent square bar assembly structure, surface galvanized, with a beautiful appearance, good rigidity, and reasonable structure.

  
  

• The main transmission reducer motor of the profiling machine and other reducer motors, as well as important components and parts, are all produced by well-known domestic and foreign companies, thereby effectively ensuring the overall performance of the equipment.
