DOE’s helium critical material designation raises supply, refining, and energy technology questions for U.S. manufacturers.
Thermal Expansion Can Make a Good Machined Part Look Out of Tolerance
A precision-machined component can pass inspection at one temperature and fail at another without any permanent change to the part. The difference may come from thermal expansion rather than poor machining. This is especially important when manufacturers inspect components immediately after machining, move them between production and quality laboratories, or Continue Reading
