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)
