Key rings

The technical precision, the classy appearance of a jewel.

The innovative open/closed principle on this key ring was devised by a major luxury leatherware brand in 2005.

Developing this product meant meeting an array of demands:

  • Finding the right spring constants,
  • Respecting close tolerances,
  • Ensuring correct alignment of parts,
  • Reconciling working clearances with finishing width,
  • Guaranteeing an immaculate appearance,
  • Achieving quality marking at the best cost,
  • Optimising means of production after a substantial increase in volumes.

All of these demands were fully factored into the production process. Each part is manually fitted with the utmost care before passing through a series of quality checks.
