Customer's specification

A precise component with thin-walled sections (nickel alloy).

Wolfensberger solution

It is possible to manufacture delicate, thin sections true-to contour without additional machining using the Precision Casting process. This complies with the dimensional-accuracy tolerances which apply to investment casting. In addition, the casting is head-treated, coated and preassembled so that the customer receives a component ready to install.
