Rosendahl Nextrom’s RX 5 crosshead is especially developed for fiber optic cable applications. During the extrusion process high reproducability and constant product replication are central values for Rosendahl.
The Rosendahl Nextrom RX 5 crosshead with linear guiding is optimized for secondary coating lines. This works for both dry as well as for jelly filled applications. It comprises of a fine tuning centering unit and a jelly unit for bubble-free jelly filling. The specially customized and adjusted needle supports the required precision during the extrusion process.
The loose tube trend shows, that small size products are getting higher in demand. And smaller products require thinner wall thickness. With a wall thickness of 0.15 up to 0.3 mm, the crosshead RX 5 meets the targets with precision. Even at geared line speeds up to 1000 m/min, the product keeps its shape and its required properties.
Rosendahl Nextrom developed additional tools like the trolley with heating zone and special crosshead fixing. This supports product centricity and keeps the crosshead fixed on the same position.
The crosshead unit is easy to handle and has proven its reliability. If you wish to see a real life example visit the company in Pischelsdorf, Austria. In the local Technology Center the loose tube line is ready to be seen during production where interested parties can bring along their local material and their individual recipe for tests on Rosendahl Nextrom‘s laboratory line.
