The continuous production line of polyurethane composite panel integrates the technology of mechanical, electrical, hydraulic and HCFC chemical polymerization of polyurethane with the automatic continuous production line composed of several units. The production line adopts the international and domestic advanced roll forming
technology, HCFC polyurethane (chemical) foaming technology, composite transmission technology, variable frequency vector technology and hydraulic control technology. The features of the line are:
1.Imported from Germany Kraussmaffei (Kraussmaffei) , the world's leading intelligent, foaming equipment;
2.Produced plate size stability is more, the surface is flat, high integrity, high feeding accuracy;
3.High Degree of Automation;
4.Simple Operation
