Bel Air Finishing was tasked with reducing manual labor and achieving a consistent, polished finish on cast silver pendants. The goal is to streamline production by cutting down, pre-polishing, and polishing silver castings efficiently while maintaining high-quality surface finishes.

At Bel Air Finishing, we recognize that achieving a flawless, polished finish is vital for decorative castings, especially in metals like brass and zinc. To meet these needs, we recommend the FM Bruni 3 Roll Burnisher, a high-performance finishing machine designed to eliminate the labor-intensive steps of traditional burnishing and wet grinding.

The FM Bruni 3 employs an innovative rolling mechanism to smooth and polish surfaces with nonabrasive, controlled pressure, preventing common defects such as tool marks or an “orange-peel” effect. This technique produces a brilliant, dense surface that resists wear and enhances durability, making it ideal for decorative pieces that require both aesthetic appeal and longevity.

For jewelry and consumer goods, the FM Bruni 3 has consistently proven its precision and versatility. Its open-trough design allows easy monitoring and quick removal of parts, further streamlining the process. In our latest video, we showcase the Bruni 3 in action on brass and zinc samples—a tower and a sasquatch—demonstrating how this single-step process, which includes wet grinding, creates a mirror-like finish directly from casting. Trusted by the jewelry industry, the FM Bruni 3 Roll Burnisher is a reliable choice for customers seeking superior quality and efficiency in decorative finishing.

To streamline the finishing process for cast silver pendants, Bel Air recommended an advanced high-energy disc finishing technique. This process effectively removes surface imperfections, smooths edges, and prepares the pendants for a polished finish. By combining precise wet grinding and polishing technologies, the solution achieves consistent, high-quality results while significantly reducing manual labor.

The Centrifugal Disc Finisher played a key role in this process, offering efficient handling of intricate jewelry pieces and delivering smooth, pre-polished surfaces that meet the exacting standards of the jewelry industry. This approach ensures faster production times, superior surface quality, and improved overall efficiency for jewelry manufacturers.
