Our Story

We started our heat treat venture under the name Beaver Heat Treating Corporation back in 1955. A lot has changed since then. We’re now Thermal Modification Technologies, Inc. We moved across town from Milwaukie to Tualatin in 2013. On the other hand, much has remained the same. We’re still family-owned. We’re still powered by a great team, and we remain grateful for the opportunity to continue serving the heat treat needs of the Pacific Northwest and beyond.

Our Mission 

We exist to strengthen products, people, and partnerships.

As heat treaters, we don't make parts; we make our customers' parts stronger. That is a great metaphor for what we aim to do for our people who, as we say around the shop, "really make the magic happen." Similarly we seek strong relationships with our customers, our vendors, and our community at large.

Our Values

We believe that values have consequences, that is, they show up day in and day out. Here's what we value, and therefore, how we act:

Character: do the right thing
Teamwork: help others
Excellence: relentlessly pursue in-spec, on-time
