Continuous PU Sandwich Panel Production Line Machine

This Continuous PU Sandwich Panel Production Line Machine has the best functions: such as anti-flaming, thermal insulation, hest insulation, sound insulation, waterproof and environmental protection.

Continuous PU Sandwich Panel Production Line Machine is mainly used in high-rise buildings and advanced office building exterior wall decoration.

This Continuous PU Sandwich Panel Production Line Machine mainly produces three profiles:
Hidden wallboard sheet, corrugated sheet and push-in type wallboard sheet (optional).
During the line working, after the roll forming system, the PU should be sprayed on the surface of panel continuously, and then through the DBL forward. During this time, the PU is foaming and solidifying. After the sandwich panel is forming completely, the shear cut off the panel according to the set length. The machine doesn`t stop during cutting.

Continuous PU Sandwich Panel Production Line Machine Main characteristic and advantage
This Polyurethane sandwich panel machine is a full automatic continuous product line. This line adopts international advanced roll forming technology, HCFC PU foaming technology, laminating transferred technology, frequency vector technology and hydraulic control technology. The whole line needs seven or ten operators to control the system.

The main characteristics are below:
1.High degree of automation: this line adopts NC servo, frequency vector and hydraulic control technology. And it uses auto length setting and cutting without stopping the line.
2.High product efficiency: the product speed is 3-7m/min (according to profile requirement, it can be adjusted steplessly), the manual production capacity is 800000 m2. (each year 250 working days and work 10 hours one day)
3.Simple operation: it adopts computer integrated control technology. It only needs to input and parameters and cutting length, the line will run automatically.
4.Low cost of production: with the improvement of degree of automation, the line needs five to seven operators to keep the line run normally.
