Extrusion Lines
Our "classic" extrusion lines stand out through tried and tested technology. The essential parts of our processing equipment have been continuously enhanced throughout the years. Our know-how is based on the experience that comes with countless start-ups, on the improvements to aggregates and components developed in long-term partnerships and, last but not least, on the trust our customers place in our capability as innovators.
Insights won through laboratory testing of various compounds are implemented and integrated.
This translates into economic benefits for our customers. At the same time, the risks related to process-relevant production technology are reduced. Our structured approach to engineering technology has generated a module-based design concept:
- extruder
- extrusion headsUpstream
- tooling
- downstream equipment
- winders and booking equipment
- control system technology
The Machine Concept
For years, the hot feed extruder determined the basic principles of today's extrusion technology. To this day, hot feed extruders are used for compounds with special process technological requirements (e.g. for truck tires) or for replacement investments within an existing production line. However, it is the cold feed pin type extruder that now dominates all tire production areas.
Especially the modern car tire production has now been completely based on cold feed technology for many years. When compared with hot feed extruders, cold feed pin type extruders offer a more economic operation - because no preheating mills are needed - which translates into a high acceptance rating for investments in new plant equipment. In addition, the investment costs for equipment and operation are further reduced because no calender is needed.
Modular Design of Extrusion Lines for Tire Production
Our extrusion heads offer a universal flow channel technology with a hydraulic hammerhead locking system to ensure a fast and safe changing of profiles in combination with a high degree of operational reliability and profile extruding precision. The extrusion head geometry and the selection of the corresponding extruders depend on the required output, the profile dimensions and the width. Various extrusion aggregates with different extrusion head widths are available to meet these demands.
