How does a watch obtain its elegant matte finish?

Shining jewelry thanks to innovative blasting technology

How does a watch obtain its elegant matte finish, and how are these beautiful, smooth structures conjured all around their cases? What wearers of these precious timepieces rarely give a second thought to: Nearly every watch case is blasted for the de-burring process. In this manner, metal- or plastic cases receive their beautiful, evenly structured surfaces. SIGG Strahltechnik keeps contemporary blasting technology for grinding, polishing and de-burring of shining pieces in the watch and jewelry production in its portfolio.

Blasting technology for an appealing watch case

A leading role, particularly for high-value watches, plays, besides an appealing watch case, also the look of the movement. After the milling process, for the de-burring, the movements are blasted with a high-quality blasting abrasive. Benefits: There are also blasting abrasives available, which do not change the color of the brass parts. Appropriate for treatments like these are injector blasting systems with a rotary basket. The rotary basket prevents fine and small parts from being wasted during the blasting, and also serves larger quantities to be processed.

Glass beads for fine jewelry

The jewelry industry, however, primarily uses wet blasting cabinets with glass beads or corundum as an abrasive. SIGG Strahltechnik keeps a comprehensive offer ready for this industry as well. Which system is the right choice, is determined by SIGG Strahltechnik specialists by means of the testing laboratory. A further issue at stake is, for example, whether the jewelry is supposed to be coated after the blasting process. Other selection criteria are size and quantity of the jewelry pieces. For large quantities, the right choice would be rotary table blasting systems by SIGG Strahltechnik.
