Jewelry Polishing

Jewelry Polishing

Jewelry polishing and burnishing by hand is a labor intensive and time consuming process and is far too expensive to use in a mass production, large-scale environment. Using mass finishing and jewelry polishing systems, jewelry manufacturers save time and money as compared to the more traditional hand finishing techniques.

Mass Jewelry Burnishing and Finishing

In the jewelry manufacturing industry, mass jewelry polishing systems can provide excellent results:

  1. Significant reductions in labor costs
  2. Increases in quality control
  3. Increases in productivity
  4. Reduced losses of precious alloys

The purpose of the process is to polish/finish jewelry in a quick and efficient manner in order to get the jewelry pieces ready for the next step in the process.

This tumbling action, combined with the proper media, will polish jewelry pieces to a beautiful brilliance. Either the MT Series Wet Barrel Mini-Tumbler System or the K14 Series Wet Barrel Tumbler System are ideal for this application and both come in a variety of barrel sizes to accommodate any capacity needs.

The Vibratory Bowl System is a widely used type because it is very effective and cost efficient.

For a truly deep brilliance, use a burnishing compound with stainless steel media. The Kramco 910 Burnishing Compound is a high lubricity, high polishing product designed with jewelry polishing in mind.
