Lorem ipsum dolor sit ares mendare hier steht Text
Infrared curing as a productivity booster
Up to 15% faster processing and 30% lower energy consumption compared to hot air methods
Rosendahl silicone extrusion line combines low-shear extrusion with advanced infrared curing to produce high-quality silicone-insulated cables. Designed for standard and ceramifying silicone compounds, the line delivers:
- Reliable infrared curing with guaranteed cross-linking rates
- Reduced energy consumption
- Minimal start-up scrap
Typical applications include cables used in automotive, EV charging, fire safety, railway, industrial, and other high-performance cable applications.
From extrusion and curing to intelligent process control, every component is engineered to work together as one integrated production system.
Low-shear silicone extrusion
Precise temperature control, gentle material processing, and integrated cooling ensure stable, high-quality silicone extrusion.
Automatic stripe feeding
Continuous material supply from the box to the extruder. Automatic strip break detection included.
Fully automated infrared curing
The 3-zone curing section ensures fast surface curing and gentle crosslinking, all managed via line control.
Guaranteed cross-linking performance
A mathematical simulation model guarantees accurate, predictable cross-linking performance.
