Norman Noble’s Noble DryEPolish

Norman Noble continues to innovate the finishing process of nitinol-based medical implants with the introduction of Noble DryEPolish. Noble DryEPolish can deburr, smooth, and polish intricate features on metallic-based implants made from nitinol, stainless steel, titanium, and cobalt chrome.

Norman Noble’s COO, Chris Noble says, “We are one of the first contract manufacturers to utilize this technology for finishing. Noble DryEPolish has many advantages over our current deburring, cleaning, electropolishing, and passivation methods. I want to thank our finishing process development team for its research and diligent testing in its quest to improve our capabilities.”

Noble DryEPolish is a dry electropolishing system for high performance nitinol next-gen implant designs. The system can improve corrosion resistance and custom polishing on selective part geometry to meet functional requirements. Noble DryEPolish encompasses the benefits of mechanical and electro-chemical processes in one single process. Straight channels or right and obtuse angles with a minimum diameter of 4mm can be internally polished. Noble DryEPolish also increases efficiency and quality through single operation full batch processing, resulting in decreased variation from part to part. Lastly, it can provide equivalent or better surface finish results compared to traditional liquid electropolishing, with less material removal, allowing for better preservation of geometry, lower surface roughness, and improved corrosion resistance.
