Lower costs thanks to weight saving
Driver Hub
Customer's specification
Weight saving by comparison with welded design and high resistance to corrosion.
Wolfensberger solution
Optimised, casting-compatible shaping has made it possible to reduce the weight by one third. The DUPLEX steel used (GX2CrNiMoN 26-6-3/1.4468) meets the very stringent corrosion-resistance requirements (lyes and aggressive chemicals etc.).

Full-service partner
Chain Link
Customer's specification
Maximum-quality component, ready to install.
Wolfensberger solution
We, as a prime contractor, are able to cover the entire value-added chain. Since we have acted as a strategic partner for many years now, we are able to offer all required machining and treatment steps. This means that the customer is able to focus on his own core competences.

Reduced machining costs thanks to precision casting
PELTON ROTOR
Customer's specification
Reducing the high machining costs.
Wolfensberger solution
It was possible to cut around two thirds of the original machining requirements by true-to-contour casting of the Pelton bowls using the ceramic precision casting Exacast®.

Precise true contouring thanks to 3D-printed cores
IMPELLER WHEEL
Customer's specification
Very true contouring using the sand-casting method.
Wolfensberger solution
The conventional manufacturing method with multi-part core segments was able to be replaced and it was possible to achieve better true contouring using a monobloc core produced by digital printing.
