“Inspired engineering. Precision Results.”


Ironwood has been active in the Electronics business since inception in 1979. We began with close tolerance molded components that are manufactured using complex, expandable tooling. That has evolved into reel-to-reel (continuous) molding and other insert molding applications using engineered materials.
