NASA and Pratt and Whitney Select Metalex to Manufacture Impeller for Space Shuttle Main Engine
In 1995, representatives from NASA and Pratt & Whitney visited Metalex. Among the visitors was Otto Goetz, NASA’s chief engineer for the Space Shuttle’s Main Engine (SSME) and one of the few remaining pioneers from Dr. Werner Von Braun’s original U.S. Space program.
The NASA team was looking for a company with precision 5-axis milling expertise required to manufacture the complex one-price impellers for the space shuttle’s turbopumps, an exceptionally difficult project. After this meeting Metalex was selected and successfully delivered a perfectly conforming 1st article of the re-designed SSME impeller in less than 6 months.

Dr. Russel Ackoff Visited Metalex
The late Dr. Russel Ackoff, Professor emeritus of the Wharton School, author of Recreating the Corporation, visit Metalex and observed:
“The visit to Metalex was very exciting and it reinforced my belief that significant progress is possible in the corporate world. Metalex has by far the most advanced manufacturing system I have ever seen, one based on using and developing employee competence and job satisfaction. It endows work with dignity and purpose. Little wonder the company’s employees extract so much satisfaction from their work.
Although the company is far from status and far from being “stuck” it appears to be eagerly awaiting the next quantum leap in the future and it wants to lead the way there. Senior management conceived and directed implementation of past jumps that have made the company the outstanding organization that it is. Senior management has been atypically open to new ideas and has been willing to try them. Now it appears to be reaching out for another break from the past.
The next break should be one that comes form the workforce blue-and-white collar. They should be organized so that they generate and implement new ideas. This increased responsibility at the working level should not discourage senior management from continuing to develop innovations, but it should not be the only, or even principle ,source of innovation”
