The path that a jewelery lock goes through until it reaches the customer is a much more meticulous process than it seems. Sub-millimeter tolerances, thousands of on-off tests and metallurgical controls; determines whether a lock is “good” or “excellent.” In this article, we describe the journey of a lock from the production line to the quality control desk.
1. Raw Material and Alloy Control
It all starts with the right alloy. Gold carat, hardness and flexibility balance are tested at the first stage of production. An incorrect alloy may cause the lock to fatigue and break over time.
2. Precision Manufacturing and Tolerance
Parts produced with modern CNC and casting technologies are measured at the micron level. Even the slightest deviation in the spring bearing or engagement point of a lock directly affects the comfort of use.
Critical Measurement Points
- Spring pressure and return time
- Docking depth and grip strength
- Surface roughness and polishing quality
3. Endurance (Fatigue) Tests
A lock is opened and closed tens of thousands of times throughout the life of the product. That's why in our laboratory the locks are put through cyclic testing that simulates real use. The aim is to guarantee that the performance of the first day is maintained for years to come.
Quality begins where it is not visible; Because true durability is only proven over time.
4. Surface Work and Final Inspection
Polishing, plating and final visual inspection; It determines both the aesthetics and skin contact comfort of the lock. A smooth surface is both more hygienic and more durable.
5. Documentation and Traceability
As Günaydın Kilit, we have our processes audited with international standards such as ISO, SEDEX, Higg Index and WCA. In this way, every lock we produce reaches our customers with a traceable and documentable quality assurance.
