helix II - special VSI multi-layer dies

Our custom-built VSI multi-layer dies can be combined with either spiral mandrel or side-fed distributors according to the customer’s choice. Depending on the materials to be processed, the optimal distribution concept is used in each case.

  • Long service life for the dies
  • Minimal expense for servicing and cleaning of the critical flow surfaces thanks to strategically positioned parting lines, without dismantling of the other components

Coatings to meet specific requirements available for:

  • Wear protection
  • Optimization of flow behavior
  • Surface sealing
  • Top-quality distribution of the functional layers across the circumference
  • Mechanically and thermally homogeneous melt distribution
  • Minimal residence time range for materials which start a process of cross-linking or thermal degradation following melting (e.g. PEX-b and EVOH)

Special application: tooling for micro and multi duct pipes
