XPS Foam Board Machine

XPS Foam Board Machine is a continuous two-stage extrusion physical foaming line. It uses polystyrene (PS) pellets as raw material, together with foaming agent, flame retardant, nucleating agent and other additives. Through melting, plasticizing, mixing, pressurized foaming, shaping and cooling, trimming and cutting, it produces closed-cell XPS extruded polystyrene insulation boards.

There are two mainstream foaming routes in the market: conventional HFC foaming type and CO₂ supercritical foaming type.

Main Components

1. Multi-component loss-in-weight batching & vacuum feeding system: precise metering and sealed conveying of PS pellets, flame retardant, nucleating agent etc.

2. Co-rotating twin-screw main extruder: raw material melting, plasticizing, mixing and pressure build-up

3. HFC foaming agent high-pressure metering & injection system: boosting and quantitative injection of foaming agent into melt

4. Cooling single screw extruder (stabilizer): melt cooling, homogenization and pressure control before foaming

5. Hydraulic screen changer: impurity filtration with non-stop screen changing

6. Special XPS foaming flat die head: wide discharge for uniform transverse thickness

7. Vacuum shaping cooling platform + traction unit: board shaping, cooling and synchronous traction

8. Online thickness testing, edge trimming & scrap crushing recycling system

9. Finished board conveyor, turnover and stacking station; optional automatic packer

10. PLC + HMI electric control system: parameter monitoring, alarm and recipe storage

Production Process

Loss-in-weight raw material proportioning → vacuum feeding into twin-screw extruder for melting and mixing → supercritical CO₂ high-pressure quantitative injection into melt → melt enters cooling single-screw for cooling, pressure stabilization and homogenization → filtration via screen changer → extrusion through flat die, pressure release and foaming → shaping and cooling → hauling → on-line thickness measurement, edge trimming → fixed-length cutting → inspection → stacking and packing; trimmed scraps are crushed and recycled for feeding.

Supply Description

Foaming injection system can be supplied separately, or a complete turnkey production line is available. Drawing customization, voltage adaptation, domestic and overseas installation & commissioning, as well as formula technical support are provided.
