Extrusion technology
The next generation of extruder screws

Boost your output by up to 40% with the latest screw and feeding zone design by Rosendahl.

The extrusion process is subject to constant change: Cable products are getting smaller. Wall thicknesses are getting thinner. Materials are being substituted. Production speeds are increasing. The process window for the extrusion process is getting narrower.
To deal with these and future demands, Rosendahl’s R&D team has enhanced their extruder screws and the corresponding feeding zones in extensive laboratory and field tests. The results are outstanding:

• Up to 40% higher throughput
• Improved melting performance
• Improved mixing quality and melt 
     homogeneity
• Less wear and tear

Screw and feeding zone – a powerful duo
Bringing the extruder screws to that new level of excellence, is the result of rigorous testing and iterative design adjustments with the support of the latest simulation software, combined with field tests at different customers’ sites. The focus of the R&D work was to refine the interaction between the extruder screw and the feeding zone. After all, the synergy between those two parts is key for maintaining a homogeneous polymer mass over the entire extrusion process.
The team itself is impressed with the results achievable. “It’s more than we imagined when we started this R&D project,” says Marc Richling, director of extrusion technology.
