BLO machine provide a special and differentiated service to all our clients that supplying production line along with various techniques and know-hows which are very useful to maintain and operate the equipment in actual work site.
Machine is to make the sandwich panel with the color steel sheet or galvanized sheet and the core of polyurethane.
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.
