FATIGUE TESTING

IMR approaches fatigue testing as a complimentary technology, not a volume business where hundreds of customers come and go on a daily basis.  Our customers work directly with the engineers who understand the science, and whose experience exceeds just fatigue testing.  We provide answers and accessibility, not just reports. 

Our customers have engineering and design challenges that often extend far beyond a simple material certification based on an ASTM specification.  They have warranty, liability, and performance claim concerns.  Their fatigue testing needs are likely to be part of a sophisticated failure analysis or product performance claim research requiring advanced SEM-EDS expertise, skilled metallographic analysis, access to published metallurgists and material scientists, unique product testing rigs, advanced chemical analysis and perhaps even access to polymer chemists and composites experts.  They don’t want to have to deal with multiple labs for one project. 

IMR provides one-stop shopping.  Our engineers are able to manage projects that span weeks or even months, multiple disciplines, and multiple iterations.  We also now carry Nadcap and A2LA accreditation for many of our fatigue testing services.

October 2012 - We are pleased to announce that IMR Portland has added high-precision, low-stress grinding to our machining capabilities. This will allow us to produce fatigue specimens in-house and shorten turnaround times.
