The ALEMO EXT130 foam sheet extrusion line is designed to extrude polyethylene and polypropylene foam sheets using direct gas injection. The design and geometry of the screw are what make the melt strength exceptional.

The ALEMO EXT130 twin-screw extruder for polyethylene and polypropylene foam sheet achieves exceptional melting, mixing, and cooling with minimal material shear. The design of the sheet die head and die determine the final consistency of the product. This ensures uniform thickness and density across the entire width of the foam sheet.

The feed screw of the foam extruder is designed to bring the material to the desired temperature with optimal gradual cooling. This is considered essential in foam extrusion for maximum density reduction, up to 25%.

ALEMO designs and develops extruders based on the production process, not the other way around, thereby achieving high uniformity in foam thickness across the entire width. ALEMO foam sheet extruders achieve higher productivity, better product quality, and lower energy consumption of less than 0.3 kWh per kg of extruded material — 40% less than Tandem extruders.

ALEMO extrusion lines are designed to offer a higher level of safety.
