Macro’s PS Foam Extrusion Line is a tandem extruder system that produces expanded polystyrene sheet (EPS) at extrusion output rates up to 700 kg/h.

The key feature of the line is a newly designed innovative cooling screw that guarantees efficient cooling of the melt and highly uniform melt temperature distribution in the secondary extruder. This not only allows extrusion to occur at elevated outputs but also creates advantageous properties within the foam structure, such as an increased proportion of closed-cells, improving the overall strength of the foamed sheet.

The die is designed so die lip adjustments can be performed without shutting down the line, saving costs on materials and labour.
