Extrusion line parts are essential for keeping insulation and jacketing production running at consistent speed, dimensional accuracy, and surface quality. From screws and barrels to crossheads, dies and tips, every component in the extruder directly affects melt flow, wall-thickness uniformity, and material consumption. Worn or out-of-tolerance parts lead to eccentricity issues, surface defects, and increased scrap, which is why reliable access to original and compatible replacements is critical for any wire and cable plant running insulation, sheathing, or jacketing lines.

We supply spare and wear parts for the extruders, crossheads, and downstream equipment used in wire and cable extrusion, covering everything from screws and barrels engineered for PVC, PE, XLPE, LSZH, and fluoropolymer processing, to crossheads and dies and tips built for precise concentricity and material distribution. Our customers run extrusion lines from manufacturers such as Maillefer, Rosendahl Nextrom, Troester, and Davis-Standard, and we provide both original and functionally equivalent components designed to meet the tight tolerances and material specifications required for high-speed insulation and sheathing production.

Beyond the extruder itself, we cover the components that keep the rest of the line running: spark testers for continuous insulation quality control, haul-off belts for stable line speed and tension, and the general parts used throughout cooling troughs, printers, and take-up sections. We also supply the electrical, pneumatic, mechanical, and hydraulic parts behind temperature control, screw drive systems, and line automation, allowing plant engineers to source replacements for the entire extrusion line — not just the extruder — through a single point of contact.

When a screw, barrel, or crosshead is no longer available from the original manufacturer — common on older or discontinued extrusion lines — our custom parts service offers a practical alternative. Through reverse engineering, we recreate worn screws, barrels, or die components from a physical sample, drawing, or basic dimensions, and through custom manufacturing, we produce new parts machined to the exact tolerances your process requires. We also offer enhanced parts with improved wear-resistant coatings or alloys, helping extend service life on screws and barrels exposed to abrasive compounds or continuous high-temperature operation.

Sourcing reliable extrusion line spare parts reduces unplanned downtime, protects insulation quality, and helps maintain consistent output across PVC, PE, XLPE, rubber, and fluoropolymer extrusion processes. Our team supports part identification, cross-referencing, and technical recommendations for extrusion equipment used across the wire and cable manufacturing industry, with worldwide shipping available to deliver directly to your facility.
