. PU Insulation Part

Specifications of sandwich panels producible: 

 Max. length   6000mm

 Max width     1000mm

 Thickness     30mm

 Equipment used

1. One “1+1” double-layer laminator for steel Panel

2. One set of PU foaming machine 

Operating principle

The sandwich panel consists of double layer CORRUGATED panel,the foam will be between these panels.

The double-layered laminator is consisted of the press and the 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. 

Constituents of Equipment

One “1+1” double-layer laminator for CORRUGATED panel

The laminator is used to make sandwich panels with the max. lenth of 6m, max. width of 1.0m and the thickness 30mm.
