Our PU sandwich panel line is one continuous and automatically line which integrate mechanism 、electrical controlling 、hydraulic system and polyurethane chemical reaction technology. The line adopts advanced international roll forming technology, polyurethane foaming technology, digital servo technology, frequency conversion vector technology and hydraulic controlling technology、 automatic stacking technology. The whole line only needs **7 operators. The features of this line are following:
1)、High automatization. The whole 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 cutting style of cut to length without machine stop, so that realize full automatically.
2)、High efficiency. The production speed is 3～7m/min（adjustable according to product forming requirement） The annual product capacity of this line can reach to ******0 M2 (count on the base of **0work days per year and *0 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 machine can make product automatically.
4)、Low production cost。Developing the machine’s automatization, the whole line only needs **7 operators to operate the machine fully, which saves much labor cost and production management cost for enterprises.
5)、Economize investment. The technical performances of this line reach the internationaladvanced level. It can replace the international product completely while its price is lower much than international product, so that economize your investment.
