Compatible with single-screw and twin-screw extruder configurations
Available in multiple L/D ratios to match existing machine specifications
Corrosion and abrasion-resistant inner surface options for filled or aggressive compounds
Custom bore diameters and flange configurations upon request
Suitable for processing PVC, XLPE, HDPE, PP, TPE, and specialty cable compounds
Full dimensional cross-referencing with OEM barrel specifications

Primary and secondary insulation extrusion for power cables
Jacketing and sheathing lines for energy and data cables
Medium and high-voltage cable production (MV/HV)
Fiber optic cable sheathing lines
Automotive wire and harness insulation
Telecommunications and coaxial cable manufacturing
Compound extrusion for filled and cross-linkable materials
Pressure and tandem extrusion head configurations

We assist in identifying the correct barrel based on your extruder model, screw diameter, L/D ratio, and compound type. Support includes dimensional cross-referencing, wear assessment, and compatibility matching with your existing screw and die head configuration.

We supply extrusion barrels for wire and cable production lines, including units compatible with leading machine manufacturers such as Maillefer, Davis-Standard, Troester, Rosendahl, Nextrom, and other OEM extruder brands used across the global cable industry. Our range covers single-screw extruder barrels and twin-screw extruder barrels in a wide variety of bore diameters, lengths, and lining specifications — making it easier to keep your production line running without long lead times.

The extruder barrel is one of the most critical wear components in any wire and cable extrusion line. It works in direct contact with the rotating screw and the extruded compound, which means it is continuously exposed to mechanical friction, thermal stress, and — depending on the material — chemical aggression. We offer barrels in nitrided steel, bimetallic, and hardened alloy versions, each suited to different compounds including PVC, XLPE, HDPE, LLDPE, PP, TPE, Halar (ECTFE), and fluoropolymers (FEP, PFA, PVDF) used in energy cables, fiber optic cables, automotive wiring, and telecommunications applications.

Dimensional compatibility is key when replacing an extrusion barrel in a cable manufacturing line. We cross-reference bore diameter, outer diameter, overall length, L/D ratio, flange configuration, feed zone geometry, and heating zone layout against your existing OEM specifications or worn barrel dimensions. Whether you operate a 45mm, 60mm, 90mm, 120mm, or 150mm extruder — or a custom size — we can source barrels that match your machine’s design envelope and process requirements.

All units are available with worldwide shipping and full technical support to assist with installation, alignment, and process optimization on your cable extrusion line.
