4. Double belt Laminator
The length of double belt conveyor with our company manufacturing is 36m,increased working length,the productivity improved by 20–30% compared with the present machine in the same producing condition.Controlled by Germany Siemens servo machine.Adopt side seal hanging system and snap-in connection way,could make fixing and demounting more quickly and easily ,saving a lot of labor.

5. Band saw cutting
We adopt tilt brand saw in conjunction with disk saw. The usage of disk saw can realize connection point cutting of roof panel for easy to installation and improve production efficiency. The usage of tilt brand saw considerably reduce impact force for saw surface, so it effectively protect panel interface. Negative pressure ventilation greatly reduces dust pollution for protect operator and prolong the service life of machine.
