#12 - Dry finishing implants

Improving surface finish can extend the functionality and lifespan of osteosynthesis implants that promote bone growth following accidents or surgery. Despite design and manufacturing improvements in recent years, implants can fail due to:

• Fretting corrosion – Fluids inside the body, mechanical stress of functionality

• Performance – Polishing, finishing processes can impact fatigue, tensile strengths; reduce biocompatibility

Medical device manufacturing demands various post-processing steps, some that require manual labor. Some parts need only slight rounding and cleaning. Others need intensive processing such as polishing. Post-processing failures can cause metal to enter patients’ bloodstreams, resulting in blood poisoning.

Eliminating and improving post-processing to improve surface finishes can improve implants and patient care. The DLyte machine range specializes in dry finishing to improve implant surface finishes.
