1) High automatization:
Full PLC computer integration controlling system with digital servo,frequency conversion

vector and hydraulic controlling technology, user-friendly design and easy operation .
2)High efficiency:
Automatic continuous production. Annual product capacity:1,000,000 M2 (250work days per

year and 10 work hours per day)
3)High Precision:
Heated air recycle oven,strictly control the temperature of PU foaming and solidification

in suitable range.
Special double belt conveyor design ensure flat surface,even thickness and anti-deformation

of the sandwich panel.
4)Environmental :Using 141B(or cyclopentane) as foaming agent,instead of carbon chloral-

fluoride,making the PU foaming treatment become environmental production craft.
5)Low production cost: Operators: 5-7 people
6)Economize investment: International advanced level performance with reasonable price.
