1. Introduction to Openwork Jewelry

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

Denne guiden dekker how to produce an openwork rose pendant and analyzes cost factors based on materials, arbeid, og bestillingsmengde.

2. Designing the Rose-Shaped Pendant

Key Design Considerations

  • Pattern Complexity (more details = higher cost)

  • Size & Tykkelse (affects material usage)

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

Software Used

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

  • Vector (Adobe Illustrator) for laser-cut designs

Example Design Specs:

  • Diameter: 25mm

  • Tykkelse: 1.2mm

  • Materiale: 925 Sterling sølv

3. Materials Selection

Materiale Fordeler Ulemper Best for
925 Sterling sølv Premium finish, anløpsbestandig Higher cost High-end jewelry
Messing (Gold-Plated) Rimelig, versatile Måtte sverte over tid Fashion jewelry
Rustfritt stål Varig, hypoallergenisk Harder to cut finely Minimalist designs

4. Manufacturing Methods

4.1 CNC maskinering

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

  • Best for: Precise geometric patterns.

  • Koste: $8–$20 per unit (Moq 50+)

4.2 Laserskjæring

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

  • Best for: Ultra-fine details (F.eks., petal textures).

  • Koste: $5–$15 per unit (Moq 100+)

4.3 Støping (Lost-wax & 3D -utskrift)

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

  • Best for: Økologisk, curved rose shapes.

  • Koste: $10–$30 per unit (Moq 20+)

4.4 Håndfremstilling

  • Behandle: Artisans cut and solder metal wires.

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

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

5. Step-by-Step Production Process

Skritt 1: CAD Design & Prototyping

  • Create a 3D model of the rose pendant.

  • Test print in wax or resin before metal production.

Skritt 2: Metal Cutting/Forming

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

  • If casting, inject molten silver into a mold.

Skritt 3: Rengjøring & Polere

  • Remove burrs with ultrasonic cleaning.

  • Polish to a mirror or matte finish.

Skritt 4: Platting (Valgfri)

  • Gold/Rhodium plating for ekstra glans.

  • Antique oxidation for vintage effects.

Skritt 5: Kvalitetsinspeksjon

  • Se etter defects, vekt, and dimensions.

  • Test plating durability (salt spray test).

6. Etterbehandling & Platingsalternativer

Finish Effekt Cost Addition
Høypolsk Mirror-like shine +$1–$3
Matt/sateng Myk, non-reflective +$2–$5
Gullbelegg Luxe rose gold/yellow gold +$3–$10
Oksidert Darkened vintage look +$4–$8

7. Kvalitetskontroll & Testing

  • Dimensjonal nøyaktighet (caliper measurement)

  • Vedheftstest for plating (tape peel test)

  • Angrise motstand (humidity chamber)

8. Kostnadsfordeling

EN. Materialkostnader

Materiale Cost per Unit
925 Sølv (25mm) $6–$15
Messing (Gold-Plated) $3–$8
Rustfritt stål $4–$10

B. Arbeid & Production Costs

Metode Cost per Unit
CNC maskinering $8–$20
Laserskjæring $5–$15
Støping $10–$30
Håndlaget $50–$200

C. MOQ Impact on Pricing

Order Quantity Price per Unit
1–50 pcs $25–$80
50–200 pcs $15–$40
200–1000 pcs $8–$25
1000+ PC -er $5–$15

Total Estimated Cost Range:

  • Masseproduksjon (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.

Beste valg?

  • Startups → ODM (lower design cost)

  • Established brands → OEM (full customization)

10. Top Manufacturers

  1. Kina: Low-cost, high-volume (Moq 500+)

  2. Thailand: Handcrafted excellence (Moq 50+)

  3. Italia: Luxury craftsmanship (Moq 10+)

11. Casestudie: 500-Unit Production Run

  • Design: Laser-cut sterling silver rose pendant

  • Produsent: Guangdong Jewelry Co. (Kina)

  • Koste: $12/enhet ($6,000 total)

  • Tidslinje: 25 dager (including shipping)

12. Konklusjon & Anbefalinger

  • Best for Budget: Laser-cut brass (gullbelagt)

  • Best for Luxury: CNC-milled 925 sølv

  • Best for Small Batches: Støping + hånd etterbehandling

Neste trinn:

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

  2. Request quotes from 3–5 manufacturers.

  3. Order samples before full production.
