What is hybrid extrusion?
Interview mit Materialexperte Dr. Herwig Juster
Advantages of combining plastic extrusion with the mechanical strengths of inserts
Hybrid extrusion is an innovative manufacturing process that combines the advantages of traditional plastic extrusion with the mechanical strength of metallic inserts. During extrusion, thermoplastic materials are directly reinforced with metal elements such as wires or cords.
The key: reinforcement takes place inline, during the continuous process, eliminating the need for additional production steps. The result is a composite profile that unites the best of both material worlds – lightweight and flexible like plastic, but stable and durable like metal.
What are possible applications of hybrid extrusion?
The range of applications is wide – wherever components need to be lightweight yet highly durable:
- Automotive engineering: Structural parts, crash absorbers, guiding systems
- Window and façade systems: Slim profiles with enhanced stability
- Sealing systems: Flexible but reinforced geometries for long-lasting use
- General lightweight design: Components requiring the balance between weight reduction and strength
Conclusion
Hybrid extrusion opens new possibilities for intelligently combining materials to create components with optimized properties. For designers and engineers, this means: greater design freedom, higher performance, and a production technology that is both technically and economically attractive.
Given the increasing demand for lighter, more efficient, and sustainable products, hybrid extrusion is a process that will continue to gain importance in the future.
