Compounding & Extrusion
USEON supplies complete compounding lines as turn-key projects: material handling, dosing, extrusion and pelletizing. Given your material and recipe, we configure the line. Start from what you make.
- Masterbatch
- Engineering & functional compounds
- Reactive & special processes
- Polyolefin finishing
- 01
Material handling
Vacuum loading and premixing.
- 02
Dosing
Loss-in-weight feeders for pellets, powder and liquid; side feeders.
- 03
Extrusion
Twin screw, triple screw, tandem or single screw.
- 04
Pelletizing
Strand, water ring, underwater or air-cooled die face.

Consultation from in-house process engineers
Given the material and the recipe, we propose the extruder, the feeding layout and the pelletizing method. You can run a test on our lab machines first.
One-stop: the whole line from one builder
Material handling, dosing, extrusion and pelletizing are designed, built and commissioned together, so the stations match each other.
Options sized to the job
Twin, triple, tandem or single screw and six pelletizing methods: the line is configured for the formula, and not larger than the job needs.
