925 Gelang rantai perak dengan zirkonia kubik: Proses pembuatan dengan diagram terperinci

Perkenalan

925 silver chain bracelets with cubic zirconia (CZ) stones are a popular choice in fashion jewelry due to their affordable luxury, daya tahan, 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, pengecer, and manufacturers understand production from raw materials to finished product.

1. Overview of Materials & Components

1.1 925 Sterling Silver

• Komposisi: 92.5% perak murni + 7.5% paduan (biasanya tembaga).

• Mengapa 925 Perak?

  • Stronger than pure silver.

  • Hypoallergenic and tarnish-resistant.

• Forms Used:

  • Silver wire (for chain links).

  • Cast silver components (for charms or connectors).

1.2 Zirkonia kubik (CZ) Stones

• Properti:

  • Lab-created diamond simulant.

  • High refractive index (close to diamond sparkle).

  • Available in multiple colors (jernih, hitam, pink, dll.).

• Common Cuts: Round brilliant, princess, zamrud.

1.3 Additional Materials

• Clasps: Lobster, spring ring, atau magnetik.

• Soldering Materials: Silver solder, flux.

• Polishing Compounds: Jewelry rouge, ultrasonic cleaners.

2. Proses pembuatan langkah demi langkah

Melangkah 1: Desain & Pemodelan CAD

• Hand Sketching (For artisanal designs).

• 3DAD Modeling (For precision in mass production).

• Prototyping (Wax or resin samples for approval).

Melangkah 2: Silver Chain Production

A. 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 (bulat, bulat telur, or cable link).

B. Pematerian & Strengthening

• Pematerian: Links are fused using silver solder.

• Pengawetan: Removes oxidation in an acid bath.

Melangkah 3: CZ Stone Setting

A. 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.

Melangkah 4: Perakitan & Finishing

1. Rantai & Charm Connection:

   • Soldering or jump rings attach CZ elements.

2. Pemolesan:

   • Tumbling for smooth edges.

   • Buffing with jeweler’s rouge for shine.

3. Pelapisan Rhodium (Opsional):

   • Adds extra brightness and tarnish resistance.

Melangkah 5: Kontrol kualitas & Kemasan

• QC Checks:

  • Keamanan batu (no wobbling).

  • Silver purity (hallmark stamping).

  • Clasp functionality.

• Kemasan:

  • Branded boxes, anti-tarnish pouches.
