The rock wool sandwich panel line is one continuous and automatic line that integrates mechanism, electrical controlling, hydraulic system and polyurethane chemical reaction technology. The rockwool sandwich panel machine adopts advanced international roll forming technology, digital servo technology, frequency conversion vector technology and hydraulic controlling technology, automatic stacking technology.

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

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.

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)

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.

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.

Zhejiang Jinggong Science and Technology Co., LTD., independently research, develop, and manufacture the PU/Rockwool sandwich panel continuous production line, which reaches the world's advanced technology, fills the blank of domestic PU/Rockwool production line manufacturing. It marks the coming of the era of localization of the PU/rock wool sandwich panel continuous production line. The mineral wool sandwich panel line manufactured by Zhejiang Jinggong Science and Technology Co., LTD. consists of the coiler system, filming, cutting, and slitting device, roll forming system, pre-heating device, rockwool system, rockwool upper and lower adhesive spraying system, pu side seal foaming machine, double belt system, double belt heating system, bandsaw system, stacker system, packing system, etc. It truly realized all the automatic integration production functions from pre-painted steel sheet decoiling to product's packaging. The maximum speed of this production line reaches 8 meters per minute, annual production of PU panel 1 million square meters.

The whole production line is exported to Jordan, Kuwait, Tonicia, Russia, Brazil, Argentina, UAE, India, and other countries. The performance of the production line got unanimous approval and favorable comments from the customers. With the development of the construction industry, PU side seal rock wool sandwich panel will be more widely used in construction field. Jinggong Science and Technology will provide the best products and top quality service to the general customers by using most sophisticated manufacturing and technology, also make our own contribution for national and even global environmental protection, energy conservation.
