Introduction

Polyurethane sandwich panels are widely used in construction sector. PU panels are made by casting polyurethane prepolymer with polyol and isocyanate. Polyurethane panels are suitable for indoor and outdoor environments. The polyurethane is formed on the surface of both sides of the steel plate or the aluminum plate through the continuous and discontinuous production line, and a variety of decorative materials can be attached to the surface of the plate. Continuous pu sandwich panel production is faster than discontinuous production line. PU sandwich panel line can be customized according to needs.

Polyurethane sandwich panels are widely used in construction sector.

Polyurethane sandwich panels are widely used in construction sector. Polyurethane foam is an excellent insulator and is therefore used in building, wall and roof insulation. It is also used in furniture, decoration etc.

In case of polyurethane sandwich panels the two outer surfaces are made up of glass fiber sheets impregnated with resin which provides strength to the panel and also acts as moisture barrier preventing moisture from entering into the core between glass fiber sheets from either side creating a water tight seal around it.

In another type of sandwich panel one or both sides may be made up of foamed polystyrene plastic instead of glass fiber sheets. The core material between these two layers can vary depending on use but usually it is some kind of foam such as polyester or polyisocyanurate which has higher R value than other types due to low thermal conductivity properties.

PU panels are made by casting polyurethane prepolymer with polyol and isocyanate.

Cast polyurethane prepolymer is a light-weight material that is used in the production of PU panels. Polyurethane prepolymer is a resin that has not undergone reaction with any hardener or catalyst. The main components of cast polyurethane prepolymer include:

• Polyol &#; this is an organic compound (a molecule containing carbon, hydrogen and oxygen)

• Isocyanate &#; this is also an organic compound (a molecule containing carbon, hydrogen and nitrogen).

Polyurethane panels are suitable for indoor and outdoor environments.

Polyurethane panels are suitable for indoor and outdoor environments. They are strong and durable, waterproof, fireproof, easy to clean and install. These panels are light weight and easy to transport.

These properties make them ideal for use in places where you require a material that will stand up to heavy traffic as well as harsh weather conditions. For example, they can be used on patios or terraces where children play or pets run around without causing damage like a traditional wooden deck would do over time due to wear & tear from footsteps etcetera..

The polyurethane is formed on the surface of both sides of the steel plate or the aluminum plate through the continuous and discontinuous production line, and a variety of decorative materials can be attached to the surface of the plate. The thickness of plates used in pu can also be controlled within a certain range according to different project requirements so that it has good heat insulation performance. In addition, there are various types of surface treatment available for pu panels such as powder coating, electroplating, rubber coating and so on.

Continuous pu sandwich panel production is faster than discontinuous production line.

Compared to discontinuous production, continuous production is more efficient. Continuous production lines are made up of several PU sandwich panel machines that work together to produce panels for you. This is beneficial because it allows you to produce a high volume of panels quickly and efficiently. A continuous sandwich panel line also has the ability to produce different types of panels, which makes it easier for your company to make multiple products in one location.

Continuous pu sandwich panel production is faster than discontinuous PU sandwich panel production line because the machines are constantly running without stopping or slowing down during operation. As a result, it takes less time for one person working alone on a continuous line than someone working alone on their own individual machine at their own pace would take when making the same product using similar equipment (or even just doing manual work). Because there aren't any long breaks between steps or processes involved with making these panels (like waiting for glue curing), there's no downtime either!

PU sandwich panel production line can be customized according to needs.

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.
