Discontinuous cold room panel production line 2+2 system pu sandwich
Discontinuous PU Sandwich Panel Production Line is a good choice with Economy investment, flexible size panel, high quality.
- Machine is to make the sandwich panel with the color steel sheet or galvanized sheet and the core of polyurethane discontinuously.
- The multi-layered laminator is consisted of the press and the rail stands. Two worktables move into the press and the other two stay on rail stands. Initially, put the top and the bottom sheets inside of mould frames and then seal, after that, feed the worktables into the press. When worktables inside the press moves out orderly, the other two feed in at the same time. Upon the finish of feeding, the press will close and slant at a angle, waiting for injecting PU raw materials from the PU mixing head into different panels. Meanwhile materials start foaming and curing. At this time, mould frames on worktables moved out for taking out the finished products, then to be ready for next production cycle.
- The main laminator 2+2 produces PU sandwich panel with fixed length such as 6m, 9m, 12m, adjustable width less than 1.2m, different thickness from 50mm to 250mm by the closed molding frame
