Our History

Paragon Precision originally started as Paragon Tool, Die and Engineering in 1946.  After years of supporting local business in Southern California with their tool and die needs Paragon started manufacturing rotating components for the aerospace Industry in the early 1950’s.  From one of the first successful deliveries of the Titan Rocket Propulsion Systems rotating assemblies beginning in 1953 and many other programs Paragon shifted its focus completely to manufacturing turbomachinery components.

In the 1970’s Paragon Tool, Die, and Engineering changed its name to Paragon Precision Inc.  Most recently in 2020 Paragon Precision was acquired by Princeton Precision Group.  For over 75 years Paragon Precision has been called on by industry leading companies to produce prototypes and production needs. Paragon’s commitment to tackling some of the most complex machining products has garnered long lasting relationships with some of the world’s top companies.
