Continuous PU Sandwich Panel Line

The Continuous PU Sandwich Panel Line is an efficient and automated production equipment specifically designed for the continuous production of polyurethane sandwich panels.

sandwich panel line

The Continuous PU Sandwich Panel Line can produce various specifications of polyurethane sandwich panels, such as cold storage panels, wall panels, roof panels, and soft faced coil composite panels. These sandwich panels have excellent insulation, heat insulation, fire resistance, and sound insulation properties, and are widely used in fields such as construction, cold chain, and transportation.

The working principle of Continuous PU Sandwich Panel Line is mainly based on the foaming and curing process of rigid foam polyurethane. The two-component raw materials of hard foam are sent to the mixing head by the metering pump of the high-pressure foaming machine in a certain proportion for mixing, and then evenly distributed on the bottom surface material of the sandwich board. Subsequently, both the upper and lower surface materials are simultaneously fed into the double track laminating conveyor. The rigid foam is foamed and solidified between the upper and lower conveying chain plates of the double crawler laminated conveyor. The cured sandwich panel is cut into finished products of a certain length by a cutting machine on the production line according to production needs.

The main equipment of the Continuous PU Sandwich Panel Line includes 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, steel plate preheating device, double track machine and heating system, cutting saw, etc. In addition, auxiliary equipment such as laminating equipment, cooling equipment, automatic palletizing machines, packaging systems, and environmental protection equipment may also be equipped.

Characteristic

• Highly automated: The entire Continuous PU Sandwich Panel Line adopts advanced automation control system, realizing the full process automation production from raw material transportation, mixing, foaming, curing to cutting, greatly improving production efficiency.
  

• Product diversification: By adjusting the configuration and process parameters of the Continuous PU Sandwich Panel Line, sandwich panels of different specifications and core materials (such as rock wool and polyurethane) can be produced to meet the diverse needs of customers.
  

• Energy saving and environmental protection: The Continuous PU Sandwich Panel Line adopts energy-saving and environmental protection design, such as using efficient and energy-saving foaming equipment, recycling waste gas, etc., which reduces production costs and reduces environmental pollution.
  

• Stable Quality: The Continuous PU Sandwich Panel Line adopts advanced production processes and quality control measures to ensure the stability and reliability of product quality.

The products produced by the Continuous PU Sandwich Panel Line are widely used in fields such as construction, cold chain, and transportation. In the field of architecture, sandwich panels can be used for thermal insulation of walls, roofs, partitions, and other parts; In the field of cold chain, sandwich panels can be used for insulation and heat preservation of refrigeration facilities such as cold storage and refrigerated trucks; In the field of transportation, sandwich panels can be used for thermal insulation and sound insulation of vehicles, ships and other transportation vehicles.

The Continuous PU Sandwich Panel Line is an efficient, automated, and diversified production equipment with broad application prospects and market potential.
