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.
