3)  2 in &2 out press machine

A. Equipment used
1. One “2+2” multi-layer laminator for “6×1.2m” panels
2. One set of PU foaming machine and installation for pre-storing materials
B. Operating principle
The multi-layered laminator is consisted of the press and the rail stands.Two worktables are to move into the press and the other two stay on rail stands. Initially, put the top and the bottom facing sheets inside of mould frames and then do the necessary sealing work. 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 the injection 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 can be opened and the finished products can be unloaded to get ready for next production cycle.
