Advancing Thin-Wall Cannula Design Through Micro Molding Innovation

Achieving consistent, ultra-thin wall sections has long been a challenge in medical device manufacturing. Accumold engineers recently demonstrated how advanced micro molding techniques can overcome these limitations — producing cannulas with walls as thin as 0.004" in a single-shot process.

By eliminating traditional secondary operations such as extrusion, grinding, or bonding, this approach improves precision, reduces manufacturing complexity, and enhances scalability for high-volume production.

This video highlights the process development and engineering considerations behind thin-wall cannula molding, from material selection to tool design and dimensional control.
