Introduction of Sandwich Panel Machine 

Expandable Polystyrene Sandwich Panel Machine mainly consists of a roll forming machine and a sandwich panel laminating system. Through this line, corrugated sandwich panels can be produced directly, without the shortcoming that traditional corrugated sandwich panels have to be laminated manually after the forming of corrugated sheet. Moreover, both the roll forming machine and the laminating system can work independently. The roll forming machine of the line consists of feeding system, roll forming system and cutting system, while the lamin ating system is made up of such equipments as uncoiler, feeding, squeezing, gelatinizing, heating, laminating, edge rolling, edge turn-over, groove-making, edge pruning, 
pneumatic device, automatic cutting and PLC. The whole machine possesses advanced working crafts, merging mechanical and electrical equipments into an organic whole. Annual production of this line (eight ours a day) is about 600,000 square meters.

Machine Features

1.Beautiful appearance, low noise, high efficiency
2.Multiple function: In addition to corrugated sandwich panels, this line can be used to 
produce simple corrugated sheets, and model SWL1222 & SWL1222-98 sandwich panels.
3.The transmission of the laminating system is achieved by worm and worm gear which make the laminating speed smooth and steady.
4.The line employs advanced PLC and sets the length and cuts the panel automatically.
5.The main body is welded with type “H” section steel as its material. The surface is treated by rotoblast.
6.Rollers of the laminating system are covered with rubber, which is advantageous to the protection of the surface color of galvanized sheets and makes the equipment laminate steadily.
