ALEMO extrusion line for XPS foam profile and cornice production is designed to produce foam profiles of different shapes. The used process xps production line is hot extrusion.

This extrusion manufacturing process is characterized mainly by continuous mixing of a blowing agent (CO2) into melted polymer. The compound of various components is prepared in a mixer. Then is transported to a dosing device which feeds the mixture into the extruder.

The mixture is heated to the melting point temperature of polystyrene. After that, CO2 is added to the melted polymer mixture and fulfils the function of blowing agent. This is necessary for the production of solid foam.

The obtained mixture of polymer and gas is further mixed and cooled by special cooling units. Those units are designed to work at high pressures. The mixture is then forced through special dies (matrix) to make the desired form of the profile.

The extrusion machine head is optionally designed for single stream or two stream profile production. After extrusion, the profile is guided through a mandrel to give the final shape. Further on, the profile is cooled to keep the desired shape and dimension.

Before cutting, the profile is labelled by an in-line printing unit. The profile is cut with a millimetric precision by an automatic cutter to the desired length. Finally is transported to an area prepared for the packaging.

ALEMO offers high technology for product with high quality geometry, shape and flat surface.

The ALEMO extrusion technology offers also a fast-die changing system. It allows to change die/ product in few seconds, without stopping the extruder. This solutions gives to ALEMO customers a huge advantage over competitors. Meaning in terms of time, raw material and overall production costs reduction.

ALEMO supports the Customers also with die/product shape development according to Customer’s request and design. ALEMO extruders produce XPS profiles which are the lightest products on the market. This means lowest quantity of raw material used per linear meter of profile.
