1. Introduction to Openwork Jewelry

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

Acest ghid acoperă how to produce an openwork rose pendant and analyzes cost factors based on materials, muncă, si cantitatea comandata.

2. Designing the Rose-Shaped Pendant

Key Design Considerations

  • Pattern Complexity (more details = higher cost)

  • Dimensiune & Grosime (affects material usage)

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

Software Used

  • CAD (Rhino, Matrice, ZBrush) for 3D modeling

  • Vector (Adobe Illustrator) for laser-cut designs

Example Design Specs:

  • Diameter: 25mm

  • Grosime: 1.2mm

  • Material: 925 Argint veritabil

3. Materials Selection

Material PRO Contra Cel mai bun pentru
925 Argint veritabil Premium finish, rezistent la pată Cost mai mare High-end jewelry
Alamă (Gold-Plated) Accesibil, versatile Se poate rătăci în timp Bijuterii de modă
Oţel inoxidabil Durabil, Hipoalergenic Harder to cut finely Minimalist designs

4. Manufacturing Methods

4.1 Prelucrare CNC

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

  • Cel mai bun pentru: Precise geometric patterns.

  • Cost: $8–$20 per unit (MOQ 50+)

4.2 Tăiere laser

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

  • Cel mai bun pentru: Ultra-fine details (De ex., petal textures).

  • Cost: $5–$15 per unit (MOQ 100+)

4.3 Casting (Cere pierdută & 3D tipărire)

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

  • Cel mai bun pentru: Organic, curved rose shapes.

  • Cost: $10–$30 per unit (MOQ 20+)

4.4 Hand Fabrication

  • Proces: Artisans cut and solder metal wires.

  • Cel mai bun pentru: Custom one-of-a-kind pieces.

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

5. Step-by-Step Production Process

Pas 1: CAD Design & Prototipare

  • Creați o 3D model of the rose pendant.

  • Test print in wax or resin before metal production.

Pas 2: Metal Cutting/Forming

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

  • If casting, inject molten silver into a mold.

Pas 3: Curățare & Lustruire

  • Remove burrs with ultrasonic cleaning.

  • Polish to a mirror or matte finish.

Pas 4: Placare (Opțional)

  • Gold/Rhodium plating for extra shine.

  • Antique oxidation for vintage effects.

Pas 5: Quality Inspection

  • Check for defecte, greutate, and dimensions.

  • Test plating durability (salt spray test).

6. Finisare & Opțiuni de placare

Termina Effect Cost Addition
Înaltă poloneză Mirror-like shine +$1–$3
Matte/Satin Soft, non-reflective +$2–$5
Placă de aur Luxe rose gold/yellow gold +$3– 10 USD
oxidat Darkened vintage look +$4–$8

7. Controlul calității & Testare

  • Dimensional Accuracy (caliper measurement)

  • Plating Adhesion Test (tape peel test)

  • Rezistența la pătare (humidity chamber)

8. Defalcarea costurilor

O. Material Costs

Material Cost per Unit
925 Argint (25mm) $6–$15
Alamă (Gold-Plated) $3–$8
Oţel inoxidabil $4– 10 USD

B. Muncă & Production Costs

Metodă Cost per Unit
Prelucrare CNC $8–$20
Tăiere laser $5–$15
Casting $10–$30
Lucrat manual $50–$200

C.. MOQ Impact on Pricing

Cantitatea Comanda Price per Unit
1–50 pcs $25–$80
50–200 pcs $15–$40
200–1000 pcs $8–$25
1000+ PC -uri $5–$15

Total Estimated Cost Range:

  • Producţie în masă (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. China: Low-cost, high-volume (MOQ 500+)

  2. Thailand: Handcrafted excellence (MOQ 50+)

  3. Italy: Luxury craftsmanship (MOQ 10+)

11. Studiu de caz: 500-Unit Production Run

  • Proiecta: Laser-cut sterling silver rose pendant

  • Producător: Guangdong Jewelry Co. (China)

  • Cost: $12/unitate ($6,000 total)

  • Cronologie: 25 zile (inclusiv transportul)

12. Concluzie & Recommendations

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

  • Best for Luxury: CNC-milled 925 argint

  • Best for Small Batches: Casting + hand-finishing

Următorii pași:

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

  2. Request quotes from 3–5 manufacturers.

  3. Comanda mostre before full production.
