Project Highlights

This seven piece assembly was produced using advanced casting techniques developed at Pentz. Tooling was designed directly from CAD files and CNC machined to an accuracy the allowed the cylindrical sections of the torpedo to be "as cast” instead of being “hogged out” (machined) from a solid billet.

The completed castings met rigorous performance test and NDT inspection requirements.

The result was the US Navy was able to cut costs, improve quality and shorten lead time on production.
