925 Bracelet en chaîne en argent avec zircone cubique: Processus de fabrication avec des diagrammes détaillés

Introduction

925 silver chain bracelets with cubic zirconia (CZ) stones are a popular choice in fashion jewelry due to their affordable luxury, durabilité, and brilliant sparkle. Ce 5,000-word guide Fournit un step-by-step breakdown of the manufacturing process, supported by detailed process diagrams, to help jewelry designers, détaillants, and manufacturers understand production from raw materials to finished product.

1. Overview of Materials & Components

1.1 925 Argent sterling

• Composition: 92.5% argent pur + 7.5% alliage (généralement cuivre).

• Pourquoi 925 Argent?

  • Stronger than pure silver.

  • Hypoallergenic and tarnish-resistant.

• Forms Used:

  • Silver wire (for chain links).

  • Cast silver components (for charms or connectors).

1.2 Zircone cubique (CZ) Stones

• Properties:

  • Lab-created diamond simulant.

  • High refractive index (close to diamond sparkle).

  • Available in multiple colors (clear, noir, rose, etc.).

• Common Cuts: Round brilliant, princesse, émeraude.

1.3 Additional Materials

• Clasps: Lobster, spring ring, or magnetic.

• Soldering Materials: Silver solder, flux.

• Polishing Compounds: Jewelry rouge, ultrasonic cleaners.

2. Processus de fabrication étape par étape

Étape 1: Design & Modélisation CAO

• Hand Sketching (For artisanal designs).

• 3D CAD Modeling (For precision in mass production).

• Prototypage (Wax or resin samples for approval).

Étape 2: Silver Chain Production

UN. Chain Link Formation

1. Wire Drawing: Silver wire is pulled to the desired thickness.

2. Link Cutting: Wire is cut into equal segments.

3. Link Shaping: Each segment is bent into a loop (rond, ovale, or cable link).

B. Soldering & Strengthening

• Soldering: Links are fused using silver solder.

• Pickling: Removes oxidation in an acid bath.

Étape 3: CZ Stone Setting

UN. Bezel or Prong Setting

1. Bezel Setting (More Secure for Bracelets):

   • A silver cup holds the CZ stone.

   • The metal rim is pressed over the stone.

2. Prong Setting (More Sparkle):

   • Small metal claws grip the CZ.

B. Laser or Hand Setting

• Laser Setting: Precision for small stones.

• Hand Setting: Artisanal craftsmanship.

Étape 4: Assemblée & Finition

1. Chaîne & Charm Connection:

   • Soldering or jump rings attach CZ elements.

2. Polissage:

   • Tumbling for smooth edges.

   • Buffing with jeweler’s rouge for shine.

3. Placage de rhodium (Facultatif):

   • Adds extra brightness and tarnish resistance.

Étape 5: Contrôle de qualité & Conditionnement

• QC Checks:

  • Stone security (no wobbling).

  • Silver purity (hallmark stamping).

  • Clasp functionality.

• Conditionnement:

  • Branded boxes, anti-tarnish pouches.
