PU Foam Core Sandwich Panel Line

The PU Foam Core Sandwich Panel Line is a combination of equipment specially used to produce polyurethane foam sandwich panels. This production line usually has the ability of highly automated and continuous production, and can efficiently produce polyurethane foam sandwich panels with stable quality.

sandwich panel line

The PU Foam Core Sandwich Panel Line is mainly composed of the following equipment:

• Uncoiler: used for unwinding and conveying raw materials, such as steel plates or color steel plates.
  

• Forming machine: Press the raw materials to form the desired sandwich panel shape.
  

• Preheating device: Preheating the raw materials to improve the foaming effect of polyurethane.
  

• Foaming machine: The polyurethane raw materials, curing agent, foaming agent, etc. are mixed in a certain proportion and then injected into the middle of the sandwich board to produce foam through chemical reaction and solidify.
  

• Laminating conveyor: Laminate the upper and lower materials with the foamed polyurethane foam to form a sandwich panel.
  

• Edge trimming device: Trimming the edges of sandwich panels to obtain accurate dimensions.
  

• Cutting machine: Cut the sandwich panel into finished products according to the set length.

In addition, depending on the different configurations of the production line, it may also include unwinding systems, steel plate feeding systems, automatic steel plate docking systems, reinforcement units, corona systems, double track machines and heating systems, n-pentane foaming systems, cutting saws, laminating equipment, cooling equipment, automatic palletizing machines, packaging systems, chemical material storage systems, conveying systems, dust removal and environmental protection equipment, etc.

The working principle of PU Foam Core Sandwich Panel Line is roughly as follows:

• After being uncoiled by the unwinding machine, the raw materials are molded into the desired sandwich panel shape by the forming machine.
  

• The preheating device preheats the raw materials.
  

• The foaming machine will mix polyurethane raw materials and inject them into the middle of the sandwich board, generate foam through chemical reaction and solidify it.
  

• The laminating conveyor laminated the upper and lower materials with the foamed polyurethane foam.
  

• Edge trimming device is used to trim the edges of sandwich panels.
  

• The cutting machine cuts the sandwich panel to the set length to form the finished product.

The polyurethane foam sandwich panel has the advantages of efficient heat preservation, corrosion resistance, light weight, thin wall, stable quality, good weather resistance, etc. It is widely used in the external insulation of building exterior walls, central air-conditioning air supply ducts, steel structure wallboards and roof panels and other fields. At the same time, because the production line of polyurethane foam sandwich panels is highly automated and continuous, it is also suitable for large-scale industrial production.

At present, PU Foam Core Sandwich Panel Lines are widely used in the domestic and foreign markets. With the continuous development of the construction industry and the improvement of the requirements for energy conservation and environmental protection, the market demand for polyurethane foam sandwich panels, as a high-quality thermal insulation building material, is also increasing. Therefore, the PU Foam Core Sandwich Panel Line has a broad development prospect, and there will be more technological innovation and upgrading to meet the market demand in the future.

The PU Foam Core Sandwich Panel Line is an efficient, stable and reliable production equipment. Its products have a broad application prospect in the construction field.
