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)
✔ Yatırım kadrosu (for organic shapes)

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

2. Designing the Rose-Shaped Pendant

Key Design Considerations

  • Pattern Complexity (more details = higher cost)

  • Size & Kalınlık (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

  • Kalınlık: 1.2mm

  • Malzeme: 925 Som gümüş

3. Materials Selection

Malzeme Pros Cons En iyisi
925 Som gümüş Premium finish, kararsız Higher cost High-end jewelry
Pirinç (Gold-Plated) Ekonomik, çok yönlü May tarnish over time Moda takıları
Paslanmaz çelik Durable, hypoallergenic Harder to cut finely Minimalist designs

4. Manufacturing Methods

4.1 CNC işleme

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

  • En iyisi: Precise geometric patterns.

  • Maliyet: $8–$20 per unit (Moq 50+)

4.2 Lazer kesimi

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

  • En iyisi: Ultra-fine details (Örn., petal textures).

  • Maliyet: $5–$15 per unit (Moq 100+)

4.3 Döküm (Lost-Wax & 3D Printing)

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

  • En iyisi: Organic, curved rose shapes.

  • Maliyet: $10–$30 per unit (Moq 20+)

4.4 Hand Fabrication

  • İşlem: Artisans cut and solder metal wires.

  • En iyisi: Custom one-of-a-kind pieces.

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

5. Step-by-Step Production Process

Adım 1: CAD Design & Prototip

  • Create a 3D model of the rose pendant.

  • Test print in wax or resin before metal production.

Adım 2: Metal Cutting/Forming

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

  • If casting, inject molten silver into a mold.

Adım 3: Temizlik & Parlatma

  • Remove burrs with ultrasonic cleaning.

  • Polish to a mirror or matte finish.

Adım 4: Kaplama (İsteğe bağlı)

  • Gold/Rhodium plating for extra shine.

  • Antique oxidation for vintage effects.

Adım 5: Kalite denetimi

  • Check for defects, weight, and dimensions.

  • Test plating durability (salt spray test).

6. Bitirme & Plating Options

Finish Etki Cost Addition
Yüksek cila Mirror-like shine +$1–$3
Mat/saten Yumuşak, non-reflective +$2–$5
Altın kaplama Luxe rose gold/yellow gold +$3–$10
Oksitlenmiş Darkened vintage look +$4–$8

7. Kalite kontrolü & Testing

  • Boyutsal doğruluk (caliper measurement)

  • Plating Adhesion Test (tape peel test)

  • Tarnish Resistance (humidity chamber)

8. Cost Breakdown

A. Material Costs

Malzeme Cost per Unit
925 Gümüş (25mm) $6–$15
Pirinç (Gold-Plated) $3–$8
Paslanmaz çelik $4–$10

B. Labor & Production Costs

Yöntem Cost per Unit
CNC işleme $8–$20
Lazer kesimi $5–$15
Döküm $10–$30
Handmade $50–$200

C. MOQ Impact on Pricing

Sipariş miktarı Price per Unit
1–50 pcs $25–$80
50–200 pcs $15–$40
200–1000 pcs $8–$25
1000+ PC'ler $5–$15

Total Estimated Cost Range:

  • Seri üretim (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. Çin: Low-cost, high-volume (Moq 500+)

  2. Thailand: Handcrafted excellence (Moq 50+)

  3. Italy: Luxury craftsmanship (Moq 10+)

11. Vaka çalışması: 500-Unit Production Run

  • Tasarım: Laser-cut sterling silver rose pendant

  • Üretici: Guangdong Jewelry Co. (Çin)

  • Maliyet: $12/unit ($6,000 total)

  • Timeline: 25 günler (including shipping)

12. Çözüm & Recommendations

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

  • Best for Luxury: CNC-milled 925 gümüş

  • Best for Small Batches: Döküm + hand-finishing

Next Steps:

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

  2. Request quotes from 3–5 manufacturers.

  3. Order samples before full production.
