Shot Peening of Medical Components
In the medical industry, as metal product components become smaller, lighter, and more complex the component service life is reduced due to the added burden placed
on the parent metals inherent fatigue strength. The case study below outlines one unique solution to this problem.
IMF Case Study:
A major medical manufacturer that produces an innovative implant product line was
losing an opportunity to service the baby-boomer market due to the challenge of
matching the duration of the useful component service life and the age of the recipient
at the time of implant replacement. After an extensive engineering study, and working
with Industrial Metal Finishing, the implant manufacturer implemented a process
that increased the useful service life of the component by approximately four-hundred
percent. Additionally, the process change did not require regulatory approval. As
a result the company was able to capture an otherwise lost market segment.
The process known as shot peening, a highly controlled mechanical procedure, produces
a compressive layer on the surface of the parent metal which results in an increase
of fatigue strength. In some cases the increase is as much as eight-hundred percent.
Benefits of Shot Peening medical components:
- Increases the material fatigue life
- Increases service life of product
- Chemical and coating free solution
- Prevents formation of fatigue cracks from opening on the material surface
- Enhances resistance to corrosion and wear of material placed under repeated stress
- Provides mechanical lubricity
