top quality    PS foam sheet extrusion line     Technics flow as below:

General Polystyrene Granule (GPPS) with additive are mixed in feeding sysytem, then go into No.1 Extruder---Inject foaming agent--After filter changer, material go into N0.2 Extruder--Extruded from mold head --Cooling and Shaping--Hauling off--Winding --Finished Products—Packing.

1. It adopts Gentian type double-stage series high foam technology.
2. This equipment adopts high speed hydraulic filter changer, which has steady feature, can change the filter immediately without stopping the machine.
3. The foaming shaping machine adopts PLC control, touch screen operation, easily to operate.
4. The raw material is general polystyrene granule (GPPS). 
5. In the extruding process, foam agent (such as butane gas or LPG) is injected at high pressure.
6. After extruding, foaming, cooling, shaping and hauling off, it is winding to finished ps foam sheet rolls.
7. After vacuum forming system, the finished PS foaming sheet can be made into variety of packaging vessels ,such as fast food box ,aquatic plate,supermarket tray ,cake tray , KT board ,instant noodle bowl ,foam tray etc. 
8. It is widely used in the packing for food, fruit, and advertising industrial products, etc.
