925 Braccialetto a catena d'argento con zirconia cubica: Processo di produzione con diagrammi dettagliati

Introduzione

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

1. Overview of Materials & Components

1.1 925 Argento sterling

• Composizione: 92.5% argento puro + 7.5% lega (di solito rame).

• Perché 925 Argento?

  • Stronger than pure silver.

  • Hypoallergenic and tarnish-resistant.

• Forms Used:

  • Silver wire (for chain links).

  • Cast silver components (for charms or connectors).

1.2 Zirconia cubica (Cz) Stones

• Proprietà:

  • Lab-created diamond simulant.

  • High refractive index (close to diamond sparkle).

  • Available in multiple colors (clear, nero, pink, ecc.).

• Common Cuts: Round brilliant, princess, smeraldo.

1.3 Additional Materials

• Clasps: Lobster, spring ring, or magnetic.

• Soldering Materials: Silver solder, flusso.

• Polishing Compounds: Jewelry rouge, ultrasonic cleaners.

2. Processo di produzione passo-passo

Fare un passo 1: Progetto & Modellazione CAD

• Hand Sketching (For artisanal designs).

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

• Prototipazione (Wax or resin samples for approval).

Fare un passo 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 (girare, oval, or cable link).

B. Saldatura & Strengthening

• Saldatura: Links are fused using silver solder.

• Pickling: Removes oxidation in an acid bath.

Fare un passo 3: CZ Stone Setting

UN. Bezel or Prong Setting

1. Impostazione della cornice (More Secure for Bracelets):

   • A silver cup holds the CZ stone.

   • The metal rim is pressed over the stone.

2. Impostazione del potto (More Sparkle):

   • Small metal claws grip the CZ.

B. Laser or Hand Setting

• Laser Setting: Precision for small stones.

• Hand Setting: Artisanal craftsmanship.

Fare un passo 4: Assemblaggio & Finitura

1. Chain & Charm Connection:

   • Soldering or jump rings attach CZ elements.

2. Lucidare:

   • Tumbling for smooth edges.

   • Buffing with jeweler’s rouge for shine.

3. Rhodium Plating (Opzionale):

   • Adds extra brightness and tarnish resistance.

Fare un passo 5: Controllo di qualità & Confezione

• QC Checks:

  • Stone security (no wobbling).

  • Silver purity (hallmark stamping).

  • Clasp functionality.

• Confezione:

  • Branded boxes, anti-tarnish pouches.
