Quality Control

1. Material Inspection
Raw Material Check: Verify the composition and quality of base metals to ensure they meet specifications.
Plating/Coating Quality: Inspect electroplating (e.g., gold/silver/rhodium plating) for thickness, adhesion, and uniformity.
Allergen Compliance: Ensure nickel-free or hypoallergenic coatings if required.
2. Production Process Control
Casting & Molding: Check for defects like porosity, cracks, or uneven surfaces.
Soldering & Assembly: Ensure joints are secure and smooth without weak spots.
Polishing & Finishing: Inspect for scratches, burrs, or inconsistent textures.
3. Durability & Functionality Testing
Tarnish Resistance: Test for oxidation/corrosion under humidity or sweat exposure.
-Wear & Tear: Simulate friction (e.g., chain pull tests) to assess plating longevity.
Clasp/Closure Testing: Verify functionality and strength of hooks, lobster clasps, etc.
4. Aesthetic & Final Inspection
Visual Appeal: Ensure color consistency, shine, and design accuracy.
Gemstone/Embellishment Security: Check glued or set stones for looseness.
