Medical Bone Screw Surface Before ISF Process

Bone Screw Before ISF Process

The medical device industry is a market with no room for anything less than the highest quality and the most reliable results; after all, lives can be at stake. Medically implanted devices often have complex geometries and are composed of titanium and other superalloys, making them exceptionally difficult to hand or electropolish. Smooth surfaces are desired for corrosion resistance, sterility and reduced wear. However, traditional processing techniques fall short in achieving the desired surface finish. The isotropic surface achieved by our Isotropic Superfinish Process (ISF®­­­) offers these critical advantages to the medical industry.

The ISF Process produces proven results that contribute to the life cycle of medical devices. These ultimately effect patient outcomes and quality of life. REM ­can process titanium and other super alloys to produce a low Ra surface (Ra<2 µin.) if needed. The ISF Process also produces an extremely consistent surface, far superior to hand buffing. Additionally, the process enhances the parts sterility by removing surface crevices to eliminate gathering points for bacteria. Lastly, the ISF Process preserves critical part geometries, which is paramount for many of these components.

Some of the Medical Applications REM’s ISF Process can assist with include:

  • Blood Contact Parts
  • Bone Screws and Plates
  • Artificial Knee and Hip Implants
  • Stainless Steel Surgical and Dental Instruments

ISF Medical Part Performance Benefits:

  • Reduce Wear
  • Improve Corrosion Resistance
  • Reduce Bending Fatigue
  • Reduce Hemolysis and Thrombosis in Blood Contacting Parts
  • Improve Sterility
