What is a sandwich panel machine and how it works?

Here we are introducing Sandwich Panel Continuous Line, which can automatically and continuously produce the sandwich panels, from metal sheet uncoiling to, foam injection to finished sandwich panels output. The core material can be PUR, PIR, Rockwool, 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.
