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:
✔ pemesinan CNC (for sharp, clean edges)
✔ Laser cutting (for delicate patterns)
✔ Pengecoran investasi (for organic shapes)

Panduan ini mencakup how to produce an openwork rose pendant and analyzes cost factors based on materials, tenaga kerja, dan jumlah pesanan.

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 (Badak, Matriks, 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 Pro Kontra Terbaik Untuk
925 Sterling Silver Premium finish, tahan noda Biaya lebih tinggi High-end jewelry
Kuningan (Berlapis Emas) Terjangkau, versatile Semoga menodai seiring waktu Perhiasan mode
Baja tahan karat Tahan lama, hipoalergenik Harder to cut finely Desain minimalis

4. Manufacturing Methods

4.1 Pemesinan CNC

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

  • Terbaik Untuk: Precise geometric patterns.

  • Biaya: $8–$20 per unit (Moq 50+)

4.2 Pemotongan laser

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

  • Terbaik Untuk: Ultra-fine details (MISALNYA., petal textures).

  • Biaya: $5–$15 per unit (Moq 100+)

4.3 Pengecoran (Lilin hilang & 3D Pencetakan)

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

  • Terbaik Untuk: Organik, curved rose shapes.

  • Biaya: $10–$30 per unit (Moq 20+)

4.4 Fabrikasi tangan

  • Proses: Artisans cut and solder metal wires.

  • Terbaik Untuk: Custom one-of-a-kind pieces.

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

5. Step-by-Step Production Process

Melangkah 1: Desain CAD & 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: Pembersihan & Pemolesan

  • Remove burrs with ultrasonic cleaning.

  • Polish to a mirror or matte finish.

Melangkah 4: Pelapis (Opsional)

  • Gold/Rhodium plating untuk kilau ekstra.

  • Antique oxidation for vintage effects.

Melangkah 5: Pemeriksaan Kualitas

  • Periksa defects, berat, 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
Pelapisan Emas Luxe rose gold/yellow gold +$3–$10
teroksidasi Darkened vintage look +$4–$8

7. Kontrol kualitas & Pengujian

  • Akurasi dimensi (caliper measurement)

  • Uji Adhesi Pelapisan (tape peel test)

  • Perlawanan yang Menodai (humidity chamber)

8. Rincian biaya

A. Biaya material

Bahan Biaya per Satuan
925 Perak (25mm) $6–$15
Kuningan (Berlapis Emas) $3–$8
Baja tahan karat $4–$10

B. Tenaga kerja & Production Costs

Metode Biaya per Satuan
Pemesinan CNC $8–$20
Pemotongan laser $5–$15
Pengecoran $10–$30
Buatan tangan $50–$200

C. MOQ Impact on Pricing

Jumlah pesanan Harga per Satuan
1–50 pcs $25–$80
50–200 pcs $15–$40
200–1000 pcs $8–$25
1000+ PC $5–$15

Total Estimated Cost Range:

  • Produksi massal (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. Italia: Luxury craftsmanship (Moq 10+)

11. Studi kasus: 500-Unit Production Run

  • Desain: Laser-cut sterling silver rose pendant

  • Pabrikan: Guangdong Jewelry Co. (Cina)

  • Biaya: $12/satuan ($6,000 total)

  • Timeline: 25 hari -hari (including shipping)

12. Kesimpulan & Rekomendasi

  • Best for Budget: Laser-cut brass (berlapis emas)

  • Best for Luxury: CNC-milled 925 perak

  • Best for Small Batches: Pengecoran + penyelesaian dengan tangan

Langkah Selanjutnya:

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

  2. Permintaan kutipan from 3–5 manufacturers.

  3. Sampel pesanan before full production.
