PU 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 PU sandwich panel machine is welded by strong steel plates which ensure high strength.Machine frame adopts heat – treatment which help release the welding stress and ensure machine non – deformation.
Sand blasting treatment will keep the rust away. Carefully special bottom painting and surface – painting greatly improve anti – corrosion performance and ensure machine long life used. Adopt world – first – class branded spare parts. Quality is further guaranteed.Each machine goes a number of inspection of quality by Guangxing Technical Team before delivery.

PU Sandwich Panel Production Line Features
1. 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. Using 141B (or cyclopentane), instead of CFC as vesicant, PU foaming treatment becomes an environment-friendly production technology.
5. Special double belt conveyor design ensures flat surface, even thickness and anti-deformation of panels.
6. User-friendly design and simple operation control system: HMI together with PLC computer.
Heating System
Main frame of double belt system adopts Box – shape structure processed with overall heating treatment & stress annealing technique, ensure the stability of structure.
Hydraulic System
Panel thickness is adjusted by stable hydraulic system, ensure production precise.
Chain Plate
The steel plates of Double – belt system adopt multiple time heat treatment with stress relief annealing techinque, then multiple – time rough machining and grinding process by Numerical vertical machining centre, to guarantee the surface with high flatness. Thus it will achieve perfect flatness of the final sandwich panel.
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.
