Continuous PU/PIR Sandwich Panel Production Line, also called polyurethane sandwich panel manufacturing line/production line/machine, is an automatic production line, which is consisting of decoiler, film coating, pre-cutting, cutting equipment, roll forming system, preheating, foaming, solidification, band saw cutting, cooling, stacking and packing. The whole PU/PIR sandwich panel production line integrates technologies of mechanics, chemistry, electrical control, hydraulic pressure pneumatic and temperature control.
Jinggong is one of the leading sandwich panel machine manufacturers in China who has been specialized in providing high-quality PIR/polyurethane sandwich panel production line. The panel production line were exported to many countries, such as Poland, Brazil, Jordan, Kuwait, Saudi Arabia, Tunisia, and so on. The production line performance has got unanimous approval and favorable comment from domestic and international customers. Feel free to contact us for PIR/PU sandwich panel production line price!

Zhejiang Jinggong Science & Technology Co., Ltd., which is located in Shaoxing, Zhejiang, developed the PU sandwich panel production line by themselves. This line has reached the world's advanced technology, stopped relying on import, and entered the time that there is no PU production line manufacturer in China. It means China localization age of PU production line is coming. The continuous sandwich panel line made by Jinggong consists of decoiler, roll forming machine, preheating, high pressure foaming, double belt machine, bandsaw, stacking, packing and cooling, realizing an automatic production from uncoiling to packing. Max production speed is 12 meters per minute. Annual output is 1 million square meters.

Features of PU/PIR Sandwich Production Line
Beautiful and applicable, multiple functions, such as thermal isolation, sound isolation and flame retardance.
Using heated air recycle oven, strictly control the temperature of PU foaming and solidification in suitable range.
Using high-pressure foaming system, precise measurement, high stability, little dust in the locale, protect the worker's health.
Using 141B or Pentane as foaming agent. Instead of carbon chloral-fluoride, make the PU foaming treatment become an environmental production craft.
Special double belt conveyor, flat surface of sandwich panel, even thickness, anti-pattern
Operation system controlled by PLC computer, personal design and simple operation.
