PU Sandwich panel machine includes uncoiling system, film covering and cutting system, roll forming machine, preheating oven, high pressure foaming system, double belt conveyor, double belt heating device, cutting system, etc….The Sandwich Panel Press Machine adopts gantry lift-draw type, locates directly without any foundation. 2+2 type saves much time for panel preparation and discharge time which increase times of efficiency. The polyurethane foaming process of Guangxing can meet various needs of the construction industry. The products produced by Polyurethane Sandwich Panel Machine include: insulation board, sandwich board, etc
PU/EPS Sandwich Panel Machine
PU/EPS Sandwich Panel Machine / Sandwich Panel Production Line can produce Polyurethane (PU) foam panel, Phenolic (PF) foam board with high density, excellent quality, any sizes for multifunctional used. Polyurethane composite board is widely used in metallurgy, petroleum, automobile, mineral processing, water conservancy and other aspects of materials, with strong elastic strength, excellent wear resistance and other advantages.

PU Sandwich Panel Production Line Features
1. Sandwich panel machine can product beautiful sandwich panels with high practicality, such as insulation, sound – proofing and flame retardance.
2. Hot air circulation furnace strictly controls pu foaming and solidification temperature in suitable range.
3. Precise measurement, high stability, little dust making of the high pressure foaming system protect worker’s health from harm in producing.
4. The pu sandwich panel machine using 141B(or cyclopentane), instead of CFC as vesicant, PU foaming treatment becomes an enviroment-friendly production technology.
5. Special double belt conveyor design ensures flat surface, even thickness and anti-deformation of panels.
6. PU sandwich panel machine user-friendly design and simple operation control system: HMI together with PLC computer.

PU Sandwich Panel Machine Heating System
Our heating system heats the chain plate surface only, NOT whole machine. It is more energy saving, higher efficiency, and protecting rolling bearings avoid damage for a longer life-time used.

Sanwich Panel Machine Hydraulic System
Panel thickness is adjusted by stable hydraulic system, ensure production precise.

Sanwich Panel Production Line Chain Plate
Special strong High-strength weather-resistant steel. With bushing between pin and chain plate, avoid wearing out.Overall welding structure , protect steel unit around it , higher running precise ,longer life. Chain plate edge is sloped on both sides , can avoid bearing damage and pin damage. With the latest upgraded new technology, the chain plate flatness ±0.0.05mm, which is almost negligible. Important guarantee of the final panel flatness ±1mm only

PU Sandwich Panel Machine Box – Shape Structure
Main frame of double belt system adopts Box-shape structure pro – cessed with overall heating treatment & stress annealing technique, ensure the stability of structure.

World First Class-Branded Spare Parts
