The advantages of this rock wool sandwich panel machine are the following:

1. High automatization. The whole rockwool production line adopts one full computer integration controlling system of digital servo technology, frequency conversion vector technology and hydraulic controlling technology,which realizes whole connection, collecting control and collecting management. Adopt the cutting style of cut to length without machine stop, so that realize full automatically.


2. High efficiency. The production speed of rockwool sandwich panel machine is 3 ~ 8m/min (adjustable according to product forming requirement). The annual product capacity of this line can reach to 800000 M2 (count on the base of 250work days per year and 10 work hours per day)


3. Easy operation.Adopt collecting controlling system,using man-machine conversation. After preparing for the raw material and finishing other production requirements, input required parameters,then the machine can make the product automatically.


4. Low production cost. Developing the machine's automatization,the whole line only needs 5-8 operators to operate the machine fully,which saves much labor cost and production management cost for enterprises.
