Composite PU Sandwich Panel Line

The Composite PU Sandwich Panel Line is a combination of equipment specially used for the production of polyurethane sandwich panels. This sandwich panel is made of polyurethane foam as the core material, and the upper and lower surfaces are bonded with color steel plates, galvanized plates, aluminum plates or other soft surface substrates. It has excellent thermal insulation performance, lightweight and high strength, and is easy to construct. It is widely used in the fields of building insulation, decoration, partition, air-conditioning air supply pipes, steel structure wallboards and roof panels.

The Composite PU Sandwich Panel Line usually consists of a series of equipment, including:

• Raw material preparation equipment: equipment used for storing and transporting polyurethane raw materials (such as black and white materials and foaming agents) to ensure a stable supply of raw materials.
  

• Mixing and pouring equipment: After mixing polyurethane raw materials in a certain proportion, they are evenly poured onto the bottom surface material of the sandwich panel through a pouring machine. This step is crucial to the production line and directly affects the quality of the sandwich panel.
  

• Laminating and curing equipment: send the upper and lower materials casted with polyurethane foam into the laminating machine, and foam and solidify between the upper and lower chain plates. The laminator is usually equipped with a hot air circulation device to ensure the uniform curing of polyurethane foam.
  

• Edge trimming and cutting equipment: The cured sandwich panel is processed by an edge trimming device to obtain accurate width dimensions, and then cut according to the set product length by an automatic tracking cutting machine.
  

• Auxiliary equipment, such as feeding devices, preheating devices, side paper sticking devices, roller frames, etc., play an auxiliary and supporting role in the production process.

Characteristic

• High degree of automation: Modern Composite PU Sandwich Panel Lines usually adopt fully automated control, achieving automated production from raw material preparation to product cutting, greatly improving production efficiency.
  

• Good scalability: The Composite PU Sandwich Panel Line can add unit equipment such as drying boards, palletizing, and packaging according to customer needs, achieving multifunctional production.
  

• Stable product quality: Thanks to advanced mixing and pouring techniques, as well as precise trimming and cutting equipment, the consistency and stability of product quality are ensured.
  

• Energy saving and environmental protection: The Composite PU Sandwich Panel Line adopts energy-saving measures such as hot air circulation devices to reduce energy consumption. Meanwhile, polyurethane sandwich panels, as green building materials, comply with the national energy-saving and emission reduction policies.

With the increasing emphasis on energy conservation, emission reduction, and building energy efficiency by the country, as well as the promotion of green building policies and the improvement of energy-saving standards for new buildings, the market demand for composite pu sandwich panels will continue to grow. Especially in ultra-low energy consumption buildings and green building projects, polyurethane sandwich panels will receive more attention due to their excellent performance. Therefore, the Composite PU Sandwich Panel Line has broad market prospects and development potential.
