The foam pu sandwich panel line mainly consists of the following equipment:

• Uncoiler and coil forming machine: used for unwinding and forming upper and lower base surface materials, such as color steel plates, aluminum plates, etc.
  

• Preheating roller conveyor: Preheat the base surface material to improve the bonding effect during polyurethane foaming.
  

• Foaming machine: Mix polyurethane resin raw materials, curing agents, foaming agents, etc. in a specific ratio and pour them evenly onto the base surface material.
  

• Fabric machine: used to evenly coat the mixed polyurethane raw materials onto the base surface material.
  

• Double track machine: provides the temperature and pressure environment required for foaming and curing, allowing polyurethane to foam and solidify between the upper and lower base materials.
  

• Cut to length cutting machine: Cut the solidified sandwich panel according to the set product length.

In addition, according to the specific configuration of the production line and customer needs, it may also include 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, automatic rock wool cutting and conveying system, cutting saw, laminating equipment, cooling equipment, automatic palletizing machine, packaging system, and environmental protection equipment.

The working principle of the foam pu sandwich panel line is as follows:

• Polyurethane resin raw materials, curing agents, foaming agents, etc. are transported to the mixing head in a specific ratio by a metering pump of the infusion machine for uniform mixing.
  

• The uniformly mixed polyurethane raw materials are continuously coated on the upper and lower base materials through the reciprocating motion of the fabric head.
  

• The coated base material enters the double track machine with the tracks, and is foamed and solidified between the heated upper and lower tracks to form a shape.
  

• The cured sandwich panel is processed through trimming devices on both sides of the production line to obtain accurate width dimensions.
  

• Finally, the foam polyurethane sandwich panel is obtained by cutting the product according to the set length using a fixed length tracking saw cutting machine.

Product features:

• Efficient automation: The entire production line adopts automated control, resulting in high production efficiency.
  

• Customized production: Different thicknesses and widths of sandwich panels can be customized according to customer needs.
  

• High quality insulation performance: The produced foamed polyurethane sandwich panels have excellent insulation and heat preservation properties.
  

• Environmental protection and energy conservation: Using environmentally friendly materials and energy-saving technologies to reduce energy consumption and emissions during the production process.

Application areas:

• Exterior wall insulation of buildings: used to improve the thermal insulation performance of buildings.
  

• Central air conditioning supply duct: As the supply duct of the central air conditioning system, it has excellent insulation and sound insulation effects.
  

• Steel structure wall panels and roof panels: used for wall panels and roof panels in steel structure buildings to improve the overall insulation performance of the building.
  

• Cold chain building materials: used for building materials needs in cold chain industries such as refrigerated warehouses and cold chain logistics.

The foam pu sandwich panel line has a wide range of application prospects in various fields such as construction and cold chain due to its efficient automation, customized production, high-quality insulation performance, and environmental protection and energy saving characteristics.
