Quick Detail of Continuous PU Sandwich Panel Line

1. High automatization:
Full PLC computer integration controlling system with digital servo, frequency conversion vector and controlling technology, user-friendly design, and easy operation.

2. High efficiency:
Automatic continuous production.
Annual product capacity: 500,000 M2 (250 working days per year and 8 work hours per day)

3. High Precision:
Heated air recycle oven, strictly control the temperature of PU foaming and solidification in a suitable range.
Special double belt conveyor design ensure a flat surface, even thickness, and anti-deformation of the sandwich panel.

4. Environmental:
Using 141B (or cyclopentane) as a foaming agent, instead of carbon chloral-fluoride, making the PU foaming treatment become environmental production craft.

5. Low labor cost for production:
Operators: 5 people

6. Economic investment:
The International advanced level performance with reasonable price.

7. Multifunctional:
The Panel produced by this machine will be used for following building works:
  • Commercial/Industrial Cool rooms
  • Freezers
  • Pre-fabricated Building
  • Cool room & Freezer Doors
  • Portable Buildings
  • Shipping Container Conversion Sales/Leasing/Maintenance
