Recently, a major medical implant manufacturer invited Industrial Metal Finishing’s
president, Bob Hayden, to
participate at a shot peening symposium that was attended by a number of the company’s
principal engineering and administrative personnel as well as members of their outside
support team. The primary topic was the identification and validation of key characteristics
of the
shot peening process on their products.
The shot peening process, when preformed properly, increases the fatigue strength
of some metals as much as 400%. Through scientific testing, shot peening proves
to be a reliable and repeatable manufacturing process as long as the process parameters
outlined in the governing specification are properly monitored and maintained, however
the procedures for verification of post peening results are often not as detailed.
Post process verification is somewhat more difficult due to the varying geometry,
hardness, and chemistry of peened parts. The fatigue strength improvement is established
through a series of tests where both peened and non-peened parts are cycled to failure.
Additionally, with the introduction of non-destructive testing equipment, verification
of the desired process result – through statistical analysis – is practical and
more efficient.
If you would like technical consultation for your shot peening applications from
a member of our engineering staff please contact us.
Industrial Metal Finishing sponsors Cornell University team for second year.
The Cornell University Autonomous Underwater Vehicle team is a
group of university students who design and build robotic submarines. Autonomous
Underwater Vehicles (or AUVs) have a wide range of applications including: military,
offshore, and university research.
The Cornell University team contacted Industrial Metal Finishing
for technical and processing assistance preparing aluminum AUV parts for anodize and ensuring a required micro-surface finish.
Industrial Metal Finishing’s engineers developed a process which took the aluminum
parts from a 250+ surface finish to 32 or better micro-surface finish with minimal
material loss to maintain assembly tolerances.

metal finishing requirements please

"On behalf of the entire Cornell University Autonomous Underwater Vehicle Team I
would just like to thank you for having given us the opportunity to have partaken
in this life changing experience. Industrial Metal Finishing's contribution to our
team allowed us to turn what started out as no more than an idea into a working
AUV, Proteus. Without the contributions of Industrial Metal Finishing none
of this would have ever been possible. Our entire team is indebted to you
and your company and it is with the utmost sincerity that we thank you, once again,
for helping us to recognize our goals this year."
