Continuous PU Panel Production
How Continuous Production Works
Continuous PU panel production uses machines to make panels nonstop. Raw materials like polyurethane foam and outer layers are added to a conveyor. These materials mix and form panels as they move along. The panels are then cut to size and checked for quality. This process is fast and great for making many panels quickly.
This method is very efficient. It can produce panels at 12 meters per minute. Manufacturers can make up to 1 million square meters of panels each year. These panels, with PUR or PIR cores, are excellent for keeping heat in. Many companies now use this automated process for better quality and to meet industry needs.
Advantages of Continuous Production
Continuous PU panel production has many benefits for big projects:
High Productivity: Machines make panels faster than manual methods.
Consistent Quality: Panels made this way are more uniform and reliable.
Cost-Effectiveness: Making many panels lowers the cost per piece.
Scalability: This method can handle growing production needs easily.
The market shows how useful this method is. By 2025, the market value will reach $18.43 billion. By 2034, revenue is expected to grow to $24.13 billion, with a 7.0% yearly growth rate.

Limitations of Continuous Production
Continuous PU panel production is fast but not perfect for all projects. It works best for standard designs and large-scale production. Custom designs are harder to make with this method. Also, the machines needed for this process are expensive. Smaller manufacturers may find it hard to afford them.
Discontinuous PU Panel Production
How Discontinuous Production Works
Discontinuous PU panel production makes one panel at a time. First, outer layers like steel or aluminum are placed in a mold. Next, polyurethane foam is injected into the mold. The foam expands to fill the space between the layers. Once it hardens, the panel is taken out and checked for quality.
This method is great for making panels with special shapes or designs. It is best for smaller orders or custom projects. Unlike continuous production, this process gives more control over each panel’s details.
Advantages of Discontinuous Production
Discontinuous production has many benefits for flexible projects:
Customization: Panels can have unique sizes, shapes, or finishes. This is perfect for special architectural needs.
Lower Initial Investment: The machines cost less than those for continuous production. This is helpful for smaller manufacturers.
Versatility: You can easily switch between different panel designs or types.
Tip: For small batches or custom designs, discontinuous production is a smart choice.
Limitations of Discontinuous Production
Discontinuous production is flexible but slower. Each panel takes time to make, limiting daily output. This method may not work well for large projects needing many panels. Keeping all panels consistent can also be tricky.
Note: Discontinuous production is great for custom work but lacks the speed and efficiency of continuous production for big projects.
Comparing Continuous and Discontinuous PU Panel Production
Productivity and Efficiency
