Extrusion is a technological operation in which melt is introduced from the input material (granulate), which is continuously extruded through the profiling device or the extrusion head into the free space. This technology is used to produce finished or semi-finished products that can be classified into several basic groups. Our production falls into the group of tubes and profiles production.

This technology is based mainly on extrusion screw machines or extruders that are part of the production line, consisting of other important mechanisms.
