Struggling with Concentricity in High-Speed Cable Insulation?
In this article
In the world of high-speed wire and cable manufacturing, the margin for error is nearly zero. Whether you are producing delicate fiber optics or robust high-voltage submarine cables, the stability of your production line hinges on the precision of your tooling. A minor deviation in alignment can lead to uneven insulation, material wastage, and costly downtime.
The Heart of the Extrusion Process
The quality of the extrusion tip and extrusion dies dictates the final product’s integrity. Low- and high-temperature tooling sets for the insulated wire sector are available, with flow geometries suited to the rheology of modern polymers, so that flow stays laminar and the coating stays centred.
Why Precision Matters
Modern extrusion technology requires tools that can withstand extreme pressure and abrasive materials. Available options include:
-
Diamond-Tipped Guides: Specifically designed for high-speed cable insulation (automotive and aerospace), these guides utilize industrial diamonds to minimize friction and prevent surface defects.
-
High Concentricity: tip and die concentricity to your drawing tolerance, confirmed per order. Keeping the conductor centred is critical for the dielectric strength of high-voltage cables.
-
Material Versatility: Whether your facility processes Polyvinyl chloride (PVC), Polyethylene (PE), or advanced PEEK, carbide and Hastelloy inserts are available for the thermal stability needed for consistent output.
Beyond the Die: A Holistic Solution
The supply range goes beyond the tip and die: breaker plates for consistent material flow, and nitrogen injectors for gas-injection lines. Furthermore, we understand that tool longevity is paramount. An alumina fluidized-bath cleaning system is also available, so your extrusion tip and dies are maintained without the risk of mechanical damage common in manual cleaning.
Custom Engineering for Special Applications
Every manufacturing line has its unique challenges. Tooling is available from high-precision nozzles with bores from 1 µm up to large-dimension tools of Ø350 mm for submarine cables. Geometries can be laser- or ultrasonic-machined to suit your crosshead on request.
Maximize Your ROI
Investing in high-quality tooling isn’t just an expense—it’s a strategy to reduce the “Cost of Quality.” By minimizing material overuse and extending the life of your wear parts, Relink helps you achieve a sustainable competitive advantage in a volatile global market.
