of colour or material. Easy-handling is guaranteed by a compact and modular design, by high precision ball-centring over an adjustable and self-sealing tip-holder – or by the well-proven fine-tuning-centring which is not only requested especially in extrusion-lines for fibre-optic cables. Advanced RX5-Crosshead design keeps away process-deviations and increases quality and efficiency in extrusion-lines for micro-coaxial-, LAN- and standard power cables for automotive and non-automotive applications as well.

Within the RX Crosshead Series – available in sizes from RX2 to RX110 – the latest product launch of RX5 made by Rosendahl meets the very wide-ranged demands in the field of cable applications between 0.1 and 5mm conductor diameter. Perfectly balanced polymer distribution, temperature- and pressure-profiles guarantee a smooth and stable melt-flow across the outlet zone. RX-Type crossheads generally provide high-precision centricity, therefore preventing over-sizing cable wall-thickness and helping to save material. geometry ensures short residence time of polymer melt and enables a quick and easy change Enhanced flow-channel S&E Specialty Polymers LLC, a producer of speciality plastic compounds, has added numerous concentrates to its product portfolio.
