About Us

Inland Northwest Metallurgical Services Inc. (INMS) opened for business in the Spokane Valley in February 1996.  We are the only full scale commercial heat treating business in the Inland Northwest.  We started out small with three employees and a few furnaces and a few orders a day. We have grown to process several thousand orders per year on two shifts in nearly 20 different pieces of thermal processing equipment.

In 2008 we built an expansion and added over 7,000 square feet to our existing 10,000 square foot production facility.  We also ventured into the world of Aerospace and received our first audit and certification from NADCAP.  A couple of years later in 2010 we received our first audit and certification from The Boeing Company. 

INMS is owned by Dan Ederer of Seattle, WA.  Dan and his father Dave have been in the heat treating business for over 25 years with full or partial ownership of heat treating facilities in Seattle, Portland, Salt Lake City, and Mexico.  Although INMS is in the smallest market of the Ederer-owned facilities, we stand on our own and have a combination of over 75 years of heat treating experience.  Since the day we opened our doors, we have grown to establish an outstanding reputation for high quality and excellent customer service.
