1. Introduction to Openwork Jewelry

Openwork (or filigree) jewelry features intricate cut-out designs, making it lightweight yet visually striking. A rose-shaped pendant in this style requires precision manufacturing, typically using:
✔ CNC machining (for sharp, clean edges)
✔ Laser cutting (for delicate patterns)
✔ Investment casting (for organic shapes)

This guide covers how to produce an openwork rose pendant and analyzes cost factors based on materials, tenaga kerja, and order quantity.

2. Designing the Rose-Shaped Pendant

Key Design Considerations

  • Pattern Complexity (more details = higher cost)

  • Ukuran & Ketebalan (affects material usage)

  • Attachment Method (bail, jump ring, or integrated chain)

Software Used

  • Cad (Rhino, Matrix, ZBrush) for 3D modeling

  • Vector (Adobe Illustrator) for laser-cut designs

Example Design Specs:

  • Diameter: 25mm

  • Ketebalan: 1.2mm

  • Bahan: 925 Sterling Silver

3. Materials Selection

Bahan Pros Cons Best For
925 Sterling Silver Premium finish, tarnish-resistant Higher cost High-end jewelry
Kuningan (Gold-Plated) Terjangkau, versatile May tarnish over time Fashion jewelry
Stainless Steel Tahan lama, hypoallergenic Harder to cut finely Minimalist designs

4. Manufacturing Methods

4.1 CNC Machining

  • Proses: A computer-controlled router cuts the design from a metal sheet.

  • Best For: Precise geometric patterns.

  • Cost: $8–$20 per unit (MOQ 50+)

4.2 Pemotongan laser

  • Proses: A laser burns through metal to create intricate designs.

  • Best For: Ultra-fine details (MISALNYA., petal textures).

  • Cost: $5–$15 per unit (MOQ 100+)

4.3 Pengecoran (Lost-Wax & 3D Pencetakan)

  • Proses: Wax model → Plaster mold → Molten metal casting.

  • Best For: Organic, curved rose shapes.

  • Cost: $10–$30 per unit (MOQ 20+)

4.4 Fabrikasi tangan

  • Proses: Artisans cut and solder metal wires.

  • Best For: Custom one-of-a-kind pieces.

  • Cost: $50–$200 per unit (Labor-intensive)

5. Step-by-Step Production Process

Melangkah 1: CAD Design & Prototyping

  • Create a 3D model of the rose pendant.

  • Test print in wax or resin before metal production.

Melangkah 2: Metal Cutting/Forming

  • CNC/laser cuts the design from a sterling silver sheet.

  • If casting, inject molten silver into a mold.

Melangkah 3: Cleaning & Pemolesan

  • Remove burrs with ultrasonic cleaning.

  • Polish to a mirror or matte finish.

Melangkah 4: Pelapis (Opsional)

  • Gold/Rhodium plating for extra shine.

  • Antique oxidation for vintage effects.

Melangkah 5: Quality Inspection

  • Check for defects, weight, and dimensions.

  • Test plating durability (salt spray test).

6. Finishing & Plating Options

Menyelesaikan Effect Cost Addition
Polandia Tinggi Mirror-like shine +$1–$3
Matte/Satin Soft, non-reflective +$2–$5
Gold Plating Luxe rose gold/yellow gold +$3–$10
Oxidized Darkened vintage look +$4–$8

7. Kontrol kualitas & Testing

  • Akurasi dimensi (caliper measurement)

  • Plating Adhesion Test (tape peel test)

  • Tarnish Resistance (humidity chamber)

8. Cost Breakdown

A. Material Costs

Bahan Cost per Unit
925 Silver (25mm) $6–$15
Kuningan (Gold-Plated) $3–$8
Stainless Steel $4–$10

B. Tenaga kerja & Production Costs

Method Cost per Unit
CNC Machining $8–$20
Pemotongan laser $5–$15
Pengecoran $10–$30
Handmade $50–$200

C. MOQ Impact on Pricing

Jumlah pesanan Price per Unit
1–50 pcs $25–$80
50–200 pcs $15–$40
200–1000 pcs $8–$25
1000+ pcs $5–$15

Total Estimated Cost Range:

  • Mass Production (1000+): $10–$25/unit

  • Small Batch (50–100): $20–$50/unit

  • Custom Handmade: $80–$300/unit

9. OEM vs. ODM Production

  • OEM: You provide the design; factory produces it.

  • ODM: Factory designs & manufactures for you.

Best Choice?

  • Startups → ODM (lower design cost)

  • Established brands → OEM (full customization)

10. Top Manufacturers

  1. Cina: Low-cost, high-volume (MOQ 500+)

  2. Thailand: Handcrafted excellence (MOQ 50+)

  3. Italy: Luxury craftsmanship (MOQ 10+)

11. Case Study: 500-Unit Production Run

  • Desain: Laser-cut sterling silver rose pendant

  • Pabrikan: Guangdong Jewelry Co. (Cina)

  • Cost: $12/unit ($6,000 total)

  • Timeline: 25 hari -hari (including shipping)

12. Kesimpulan & Recommendations

  • Best for Budget: Laser-cut brass (gold-plated)

  • Best for Luxury: CNC-milled 925 perak

  • Best for Small Batches: Pengecoran + hand-finishing

Next Steps:

  1. Finalize CAD design (or use ODM catalogs).

  2. Permintaan kutipan from 3–5 manufacturers.

  3. Sampel pesanan before full production.
