Ranor, Inc. was founded in 1956 by Robert A. Normandin Sr. and started out in a 18,000 square foot manufacturing space in Fitchburg, MA.

Ranor's reputation for fabricating and machining demanding parts, delivered on-time, quickly spread and its customer base soon expanded to include OEMs in the steam turbine, paper-making and machine tool industries.

By 1975 Ranor had outgrown its original facility and moved to its present location in Westminster, MA. Ranor's fast turn around time and its fresh approach to working with its customers' representatives created more and more opportunities for the company. Numerous expansions to both its facilities and Ranor's capabilities ensued.
