Main characteristic and advantage
This rock wool sandwich panel line 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.
