Research and development at Rosendahl Nextrom
We are permanently researching and testing new material components.
energy-efficient silicone extrusion
Infrared curing for silicone
To make silicon cables resistant to high temperatures, they need to be cross-linked. Rosendahl machines rely on infrared curing. Compared to other cross-linking methods, infrared curing is more efficient and flexible, with minimum scrap rates and easily controllable parameters. It is even up to 15% faster than hot air systems and consumes around 30% less power during production.
