About Thompson

Mission Statement

Founded in 1963 by Wally Thompson, Thompson Foundry has been providing casting services to clients from all over the world. Providing unparalleled customer service and exceeding customer expectations are ideals that Thompson Foundry proudly upholds.

Products and Services

Thompson Foundry is a ferrous casting operation capable of producing 1 off castings to large runs of castings.

We produce castings in Ductile Iron, Cast Iron, Ni-Hard, Hi-Chrome White Iron, Ni-Resist, corrosion resistant Stainless steel, Heat resistant Stainless steel, Manganese steel, mild steel, alloy steel.

We manufacture UNIGRATE replacement parts for power boilers, recovery boilers.

We have extensive experience in the casting of pump parts including stage pump bowls, volutes, impellers, stuffing boxes, bearing housings, gears etc.

We can provide custom casting services and are able to work from drawings or existing parts. All the steps from patterns to completion, including casting, solidification modeling using SUTcast, machining, and supplying completed assemblies is done in our facility.

We are often called upon when the castings are difficult to produce or have tight time lines for delivery, With our four induction we have the ability to schedule various alloys for production on the same day. Casting weights up to 700 lbs. in Steel alloys and 1700 lbs in cast iron and ductile are available.
