Formed Draped Medical Buttons – Deburr

A precision components manufacturer in the San Diego, CA region needed to remove burrs from formed steel drape buttons produced through a stamping operation for medical applications. The objective was to develop a vibratory finishing process capable of consistently deburring the formed components while preventing part nesting and stacking that could interfere with effective finishing.

Bel Air developed a vibratory finishing process for formed steel drape buttons used in medical applications. The process was designed to remove burrs and improve edge quality while maintaining part geometry.

A primary challenge involved the tendency of the stamped components to nest and stack during processing. This created several finishing challenges:

• Limited Media Access: Finishing media could not consistently reach all surfaces of the part.
• Inconsistent Deburring: Burr removal varied when components remained stacked together.
• Part Separation Challenges: A standard vibratory finishing process alone was not enough to keep the formed components separated throughout the cycle.

To address these challenges, Bel Air engineered a specialized vibratory finishing solution that incorporated berms and pneumatic features to improve part separation and media flow throughout the process. By reducing nesting and improving media contact, the system allowed the components to be deburred more consistently and uniformly.

The result was a repeatable deburring process that improved edge quality, reduced the effects of part stacking, and helped overcome a common challenge associated with formed and stamped components.

Custom vibratory finishing solution developed to improve part separation and deburring consistency.
