Einführung

In today’s jewelry market, consumers demand not only aesthetic appeal but also safety, Haltbarkeit, und hypoallergene Eigenschaften. Jingying, as a leading OEM jewelry manufacturer, specializes in producing nickel-free silver jewelry mit high-polish finishes, Anlaufbeständigkeit, Und water resistance. This article explores our advanced manufacturing processes, Materialauswahl, and quality control measures that ensure premium-quality, hautfreundlich, and long-lasting jewelry.

1. Nickel-Free Silver Jewelry: Safety & Einhaltung

1.1 Why Nickel-Free?

  • Hautsicherheit: Nickel is a common allergen, causing contact dermatitis in 10–20% of the population.

  • Vorschriftenregulierung: Meets EU Nickel Directive (ERREICHEN), Kalifornischer Vorschlag 65, and other international standards.

1.2 Materials Used in JINGYING’s Nickel-Free Jewelry

Material Zusammensetzung Eigenschaften
925 Sterlingsilber 92.5% Silber + 7.5% Kupfer (Nickel-Free Alloy) Hypoallergen, tarnish-resistant with proper coating
Argentium Silber 93.5% Silber + 6.5% Germanium Highly tarnish-resistant, brighter than traditional sterling silver
Rhodiniertes Silber 925 Silber + Rhodiumbeschichtung Scratch-resistant, ultra-shiny, Nickelfrei
Vergoldetes Silber 925 Silber + 18K Goldbeschichtung Luxurious appearance, nickel-free underlayer

1.3 Testing for Nickel Content

  • DMG Test (Dimethylglyoxime Spot Test) – Detects nickel leaching.

  • Xrf (Röntgenfluoreszenz) Analyse – Ensures compliance with international standards.

2. High-Polish Finishing Techniques

2.1 Polishing Process

  1. Vorpolieren (Rough Finishing)

    • Stolpern – Barrel polishing with stainless steel media for initial smoothing.

    • Einreichung & Schleifen – Removing casting seams with 600–1200 grit sandpaper.

  2. High-Polish Buffing

    • Muslin Wheel + Diamond Compound – Achieves mirror-like shine.

    • Ultrasonic Polishing – For intricate designs.

2.2 Advanced Finishing Options

  • Mirror Polish – Reflective, ultra-smooth surface.

  • Satin Finish – Soft, brushed look.

  • Florentine Finish – Cross-hatched texture.

3. Anschließende Beschichtungen

3.1 Why Jewelry Tarnishes?

  • Oxidation: Silver reacts with sulfur in the air, forming black silver sulfide.

  • Moisture & Chemicals: Perfume, Schweiß, and chlorine accelerate tarnishing.

3.2 JINGYING’s Anti-Tarnish Solutions

Verfahren Wie es funktioniert Vorteile
Protective Lacquer (E-Coating) Clear epoxy/polyurethane layer blocks air exposure Invisible shield, lasts 6–12 months
Rhodiumbeschichtung Electroplated rhodium layer (0.1–0.3 microns) Scratch-resistant, ultra-bright, lang anhaltende
Anti-Tarnish Silver Alloys (Argentium) Germanium reduces sulfur reaction Von Natur aus anlaufgeschützt, no coating needed
Benzotriazole (BTA) Passivierung Chemical dip forms a protective molecular layer Extends shine between cleanings

3.3 Testing Tarnish Resistance

  • Salzsprühtest (ASTM B117) – Simulates years of wear in 24–48 hours.

  • Sulfur Chamber Test – Accelerates tarnish formation for quality checks.

4. Water-Resistant Jewelry

4.1 Why Water Resistance Matters

  • Daily Wear: Showers, swimming, and handwashing can damage jewelry.

  • Langlebigkeit: Prevents corrosion and loosening of gemstone settings.

✔ Waterproof Sealants – Silicone-based coatings for added protection.
✔ Enhanced Prong Settings – Prevents gemstones from loosening in water.

4.3 Water Resistance Testing

  • Immersion Test – Submersion in water for 24 hours to check for damage.

  • Steam Test – Exposes jewelry to high humidity.

5. Qualitätskontrolle & Zertifizierung

5.1 JINGYING’s QC Process

  1. Material Inspection – XRF testing for metal purity.

  2. Surface Check – Microscope inspection for polishing defects.

  3. Coating Adhesion Test – Tape peel-off (ASTM D3359).

  4. Simulation tragen – Taber abrasion test for scratch resistance.

5.2 Zertifizierungen

  • ISO 9001 – Quality management compliance.

  • SGS/ROHS -Berichte – Nickel-free verification.
