The composite pu sandwich panel machine usually consists of units such as an uncoiler, a preheated unpowered roller conveyor, a foaming machine, a mobile fabric machine, an upper uncoiler platform, a molding machine, and a double track machine.

• Uncoiler: responsible for unwinding and conveying metal coils, with manual neutralization and tension control function to ensure smooth conveying of coils.
  

• Preheating non powered roller conveyor: Preheating metal coil, aluminum foil, fiberglass cloth, non-woven fabric and other substrates to prepare for subsequent foaming and compounding.
  

• Foaming machine: Using a low-pressure continuous foaming machine or a high-pressure foaming machine, the polyurethane original solution and curing agent are mixed in a certain proportion and evenly sprayed between the substrates to form a foaming layer.
  

• Mobile fabric machine: responsible for evenly spreading the mixed polyurethane raw materials between the boards.
  

• Upper unwinding machine platform: used to support the upper unwinding machine and ensure the smooth transportation of the upper surface material.
  

• Compression molding machine: to press the composite board into the desired shape and strength.
  

• Double track machine: completes online foaming and shaping of polyurethane, ensuring the flatness and consistency of thickness of the board surface.

Characteristic

• High precision and efficiency: Advanced automation control system is adopted to achieve zone control and emergency stop protection functions, improving production efficiency and product quality.
  

• Diversified products: Support the expansion of drying and stacking units, and can produce diversified products such as double-sided color panel sandwich panels.
  

• Energy saving and environmental protection: By using electric heating tubes combined with fuel stoves, the double belt machine can be quickly heated to the required temperature for production, and the heating power can be adjusted according to the actual situation to save energy.
  

• Easy to maintain: The equipment structure design is reasonable, easy to disassemble and maintain, reducing the labor intensity of on-site construction.

Composite pu sandwich panels are widely used in various construction fields such as public buildings, industrial plants, purification engineering, and modular houses due to their excellent thermal insulation performance, flame retardancy, air tightness, sound insulation performance, and green environmental protection. At the same time, it can also be used for insulation of ventilation ducts in central air conditioning, as well as pipelines in petroleum, chemical, heating, municipal and other industries.

At present, there are multiple brands of composite pu sandwich panel machines on the market, and prices vary depending on factors such as brand, model, and configuration. When making a purchase, users should choose based on their actual needs and budget. At the same time, attention should also be paid to selecting suppliers with good after-sales service and technical support to ensure the normal operation and long-term use of the equipment.

The composite pu sandwich panel machine is an efficient, energy-saving, and environmentally friendly industrial equipment with broad application prospects in the fields of construction and insulation.
