Our History


Peters Machine started in September of 1979 as a job shop machining company operating within a 3,000 square foot building. Caterpillar was the major customer at the time.


Through the years the original owner dabbled in boiler and heat exchanger repairs which transformed into a phase of machining and drilling precision holes for tubes in tube sheets and support baffles.


Since the mid 1990's, Peters Machine, Inc. has progressed and grown with fabricators of pressure vessels focusing as we do today on heat exchanger fabricators and complimentary industries. We now have over 20,000 square feet of manufacturing space with state of the art equipment to satisfy and service our customers. Click here to view our recent expansion and acquisitions.


PMI has continued to base its operation on three core principles: provide unsurpassed quality, price our services competitively, and provide on-time delivery. This philosophy has allowed PMI to grow even in challenging times. We appreciate the opportunity to serve your company and hope that we can include you in our PMI future.
