Extrusion
At Talleres PENA, S.L., we design, manufacture and refurbish high-performance screws and barrels for extrusion applications, tailored to each process, polymer and operating environment.
Our advanced bimetallic technologies and heat treatment processes deliver exceptional wear resistance, superior thermal stability and consistent throughput, even when processing highly filled compounds, abrasive materials or corrosive formulations.
Manufacturing Capabilities
- Diameters from Ø18 mm to Ø450 mm
- Unlimited manufacturing length capabilities (no L/D restrictions)
- Precision machining tolerances ≤ 0.01 mm
- Integrated grinding, heat treatment, nitriding and 3D metrology processes
- Full compatibility with single-screw and twin-screw extruders, both co-rotating and counter-rotating
Alloys
Our barrels are manufactured from carefully selected alloy steels, with or without bimetallic lining technology, depending on the application requirements.
