About Arenz
Arenz GmbH & Co. KG in Meckenheim specialises in plasticising and wear technology for the plastics and rubber processing industry. The company manufactures plasticising screws (pin-type, three-zone and barrier screws), wear-resistant barrels, bushings, non-return valves and feed rolls as well as single-screw extruders and co-/counter-rotating systems in OEM quality. Manufacturing takes place in the company's own workshop using modern CNC technology (turning and milling), complemented by carbide coating and surface treatment. Materials include nitriding steel, bimetal and HIP materials. In addition to new production, Arenz offers regeneration, repair and overhaul of screws, barrels and extrusion systems, wear measurement and process optimisation of plasticising. With more than 55 years of experience and over 50,000 manufactured components, the company operates internationally and services extruders and multiplex extrusion heads worldwide.
