When it comes to producing high-quality polyurethane (PU) sandwich panels, precision and efficiency are paramount. At Fineagles Advance Engineering, we take pride in offering state-of-the-art PU sandwich panel production lines that redefine the industry standards. In this article, we’ll unravel the composition and structure of our cutting-edge PU sandwich panel production line.

 

Understanding the PU Sandwich Panel Production Line

The PU sandwich panel production line is a marvel of modern engineering—a fully automated system designed to efficiently manufacture an array of exquisitely shaped and versatile polyurethane sandwich panels. Renowned for its durability, ease of management, technology that rivals advanced European counterparts, and competitive pricing, this equipment has earned accolades both domestically and abroad. Customers across Europe, Asia, the Middle East, Russia, and beyond have embraced it wholeheartedly.

Quality and Sustainability at the Core

Our PU sandwich panels are characterized by their exceptional strength and enduring insulation properties. What sets us apart is our use of polyisocyanurate (PIR) with inherent flame retardancy, ensuring that our panels meet stringent safety standards. Moreover, we prioritize environmental responsibility by incorporating HCFC-14b blowing devices and pentane environmental protection materials, making our production line not just efficient but also environmentally conscious—a true “green” solution.

Deconstructing the Components

Now, let’s delve into the components that make up our PU sandwich panel production line:

1. Unwinding Machine and Inlet Parts

• The unwinding machine is the initial feeding point that stabilizes the coil for the upper and lower parts of the sandwich panel.
• Equipped with a core rod-type hydraulic automatic operation, it offers both convenience and precision.
• The 2+2 system production equipment unit eliminates the need for frequent coil changes, ensuring uninterrupted high-capacity sheet production.

2. Rolling Molding Machine

• This device continuously shapes the sandwich panel when the steel coil, fed from the unwinding machine, passes between the upper and lower sections of the metal roller.
• It is versatile and capable of creating a wide range of aesthetically pleasing wall and roof panels.
• The card-type and rail-wheel design allows for easy adaptation to various panel shapes.

3. Polyurethane Foaming System

• Comprising nozzles, pumps, solution storage tanks, catalysts, gases, and a crossbeam, this system ensures even and precise spraying of polyurethane solution.
• Precision and maintenance reliability are central to its design.
• An intuitive control panel grants users the ability to manage critical foaming process data.

4. Overlay Unit

• This component applies constant pressure and heat to the upper and lower steel plates, facilitating the bonding process with the polyurethane foam core.
• Its robust construction, coupled with side retaining blocks, allows for quick product replacement.

5. Panel Cutting Unit

• Utilizing saws, this unit cuts the laminated panel produced in the previous step to the required length.
• Different cutting methods, such as rotary cutting and saw cutting, can be employed to meet customer specifications.

6. Panel Cooling Conveying Unit

• For thicker polyurethane sandwich panels, sufficient time is needed for complete hardening.
• The cooling conveyor provides the necessary time for panels to fully harden before they proceed to stacking and packaging.

7. Automatic Stacking Machine

• Serving as an automatic stacking mechanism for finished products, it can continuously load the desired quantity through vacuum suction plates or a lifting conveyor system.
• For roofing materials, cross-stacking is available when needed.

8. Panel Packaging Unit

• This unit envelops the panels, loaded onto the automatic stacking machine, with plastic film, ensuring secure packaging from all sides.
• An integrated tray system facilitates the insertion of EPS blocks, simplifying transportation and storage.
