XPS heat insulation plate is considered t be the best insulation material in the market. Granules from recycled EPS plate, as the main material, go through the die foaming extruder, calibrator, haul-off and cutting unit. with lower density, water absorption, thermal conductivity and vapour penetrability than of other kinds of heat insulation plates, XPS heat insulation plate features with high strength, low weight, air tightness, corrosion resistance and low cost. Therefore this plate can be widely used in house insulation system, in cold storage, camps, barns and civil construction, in heat insulation system of apartment, office building and workshops.

XPS heat insulation plate extrusion line has two types: single screw tandem extruder type and co-rotation parallel twin screw extruder. the model is like following: 135/150 single screw tandem extruder type and 75/150 co-rotation parallel twin screw extruder and single screw extruder. Because of high mixing efficiency, co-rotation twin-screw extruder can process material of different components.

Newly designed vacuum forming machine by Gwell, calibrating the plate by vacuum negative pressure, can lower the density of product and cut down the production cost in the condition that quality of plate can be well kept.
