Oscillating masses

Décovi SA is regularly chosen by the biggest watch brands for the production, laser engraving and decoration of oscillating weights.

The company Meyer Sintermetall AG in Studen supplies us with heavy metal blank washers. These are made from pressed tungsten powder and placed in moulds of various diameters. They are then annealed and calibrated in the furnace (sintering) to avoid tension in the material. The density thus obtained is 18.1 kg/dm3 or other densities on request.

We then carry out the turning of the blanks, the milling, the engraving (laser or mechanical), the deburring, but also the decorations (snail, côtes de Genève, circular graining, surface treatment, sparing and pad printing). Assembly and riveting are also possible in the case of so-called “bi-metal” masses. We also propose the assembly of the ball bearing.

Our oscillating masses can be marked with the “Swiss made” seal, to the complete satisfaction of our renowned customers.
