Here we introduce the sandwich panel continuous production line, which can use the sandwich panel machine to automatically and continuously produce sandwich panels, from metal sheet uncoiling to foam injection to finished sandwich panel output. The core material can be PUR, PIR, rock wool, phenolic.
The PU/PIR line includes the following parts: uncoiling system, roll forming machine, preheating oven, foam machine, accessories of foaming system, double belt conveyor, double belt heating device, cutting system, cooling system, stacking system, packing system, electric system, etc.
The product of this line sandwich panel is a new type building material, which has the function such as good flame retarding, keep warm, heat insulation, sound insulation, waterproof, handiness, environmental protection and so on. It is widely applied in protection and decoration of outside wall for tall building and first-class office building. It can do protection, keep warm and flame retarding.
Our line annual production capacity is 800000 square meters. (250 working days per year, 10 hours working time per day.)
This production line can mainly produce roof panel, cold storage panel and wall panel. Or any other profiles requested by buyer, the machine can be customized.
We welcome you to catch a glimpse of the video:

Working flow
Feeding coil ------- uncoiling material -------- Film covering (Pre-cutting) -------- edge slitting (waste edge rewinder) -------- Roll forming ------- Preheating material ------- mixed Foaming/glue spraying ------ Laminating in double belt conveyor ------- Band Saw Cutting product ------ Run out conveyor -------- Cooling ---------- Automatic stacking product -------- packing --- Output the finished sandwich panels
The following describes how the sandwich panel machine works:
Material feeding: Outer layers and core material are fed into the machine.
Bonding: Adhesive is applied, and layers are bonded to create a sandwich structure.
Compression: Panels undergo compression for strong bonding.
Trimming and cutting: Excess material is trimmed, and panels are cut to size.
Quality inspection: Panels are checked for adherence to standards.
Stacking and packaging: Finished panels are stacked and packaged for delivery.
