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:
✔ Prelucrare CNC (for sharp, clean edges)
✔ Tăiere cu laser (for delicate patterns)
✔ Turnare de investiții (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 (Rinocer, Matrice, ZBrush) for 3D modeling

  • Vector (Adobe Illustrator) for laser-cut designs

Example Design Specs:

  • Diametru: 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 (Placat cu aur) Accesibil, versatil 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 Fabricare manuală

  • 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: Design CAD & 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.

  • Dacă turnare, 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 pentru un plus de strălucire.

  • Antique oxidation for vintage effects.

Pas 5: Inspecție de calitate

  • 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 Moale, 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. Costuri materiale

Material Cost pe unitate
925 Argint (25mm) $6–$15
Alamă (Placat cu aur) $3–$8
Oţel inoxidabil $4– 10 USD

B. Muncă & Costuri de producție

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

C.. MOQ Impact on Pricing

Cantitatea Comanda Preț pe unitate
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.

Cea mai bună alegere?

  • Startups → ODM (lower design cost)

  • Established brands → OEM (full customization)

10. Top Manufacturers

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

  2. Tailanda: Handcrafted excellence (MOQ 50+)

  3. Italia: 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 & Recomandări

  • Best for Budget: Laser-cut brass (placat cu aur)

  • 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.
