Electronic Pin – Brass & Bronze Wire Forms

Bel Air Finishing was tasked with developing an efficient process to radius the cut ends of brass and bronze wire forms used in electronic pins. The goal was to replace the customer’s 48-hour rotary tumbling process with a faster, more effective solution that maintains quality and consistency.

To meet the customer’s requirements, Bel Air Finishing recommended the High-Energy Centrifugal Barrel Finisher. This advanced system significantly reduced finishing time from 48 hours to just 1 hour while delivering superior surface preparation and edge radiusing. The process effectively deburred and polished the wire forms using both wet and dry finishing methods, providing consistent, high-quality results for electronic components.
