FDC (fast dimension change) in pipe extrusion

Complete lines for quick, in-line dimension change from a single source

Pipe manufacturers aiming to be competitive in production these days need extrusion lines which are powerful, flexible and quickly adjustable, as well as cost-efficient in operation. To meet these requirements, we have developed a system for automatic pipe dimension change during production. The system can be delivered as a complete solution, or the customer can choose individual components to retrofit his line.

  • Efficient extrusion line with high throughput
  • Material savings thanks to reduced change-over times
  • High flexibility as to pipe geometry and production planning
  • High-performance extruders along with an inner pipe cooling system ensure highest productivity with low energy consumption
  • Adjustable components over a particularly large diameter range
  • Modular concept, from changing one adjustable component to a complete, automatically adjustable extrusion line, e.g. diameters 200 - 630 mm, comparable to standard extrusion lines
  • Simple handling thanks to an extended control concept for automatic dimension change
  • Excellent pipe quality with homogeneous pipe surface and even wall thickness distribution
  • The FDC system is suited for the production of PE-HD single layer, as well as co-extruded multi-layer pipes
