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 machining (for sharp, clean edges)
Laser cutting (for delicate patterns)
Investeringsstøbning (for organic shapes)

Denne vejledning dækker how to produce an openwork rose pendant and analyzes cost factors based on materials, arbejdskraft, og ordremængde.


2. Designing the Rose-Shaped Pendant

Key Design Considerations

  • Pattern Complexity (more details = higher cost)

  • Størrelse & Tykkelse (affects material usage)

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

Software brugt

  • CAD (Rhino, Matrix, 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 Fordele Ulemper Bedst til
925 Sterling sølv Premium finish, anløbsbestandig Højere omkostninger High-end jewelry
Messing (Forgyldt) Overkommelig, alsidig Må pløje over tid Mode smykker
Rustfrit stål Holdbar, hypoallergenisk Harder to cut finely Minimalistiske designs

4. Manufacturing Methods

4.1 CNC bearbejdning

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

  • Bedst til: Precise geometric patterns.

  • Koste: $8–$20 per unit (MOQ 50+)

4.2 Laserskæring

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

  • Bedst til: Ultra-fine details (F.eks., petal textures).

  • Koste: $5–$15 per unit (MOQ 100+)

4.3 Casting (Lost-Wax & 3D Udskrivning)

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

  • Bedst til: Organic, curved rose shapes.

  • Koste: $10–$30 per unit (MOQ 20+)

4.4 Håndfremstilling

  • Behandle: Artisans cut and solder metal wires.

  • Bedst til: Custom one-of-a-kind pieces.

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


5. Step-by-Step Production Process

Trin 1: CAD Design & Prototyping

  • Create a 3D model of the rose pendant.

  • Test print in wax or resin before metal production.

Trin 2: Metal Cutting/Forming

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

  • If casting, inject molten silver into a mold.

Trin 3: Rensning & Polering

  • Remove burrs with ultrasonic cleaning.

  • Polish to a mirror or matte finish.

Trin 4: Plettering (Valgfri)

  • Gold/Rhodium plating for extra shine.

  • Antique oxidation for vintage effects.

Trin 5: Kvalitetsinspektion

  • Check for defects, vægt, and dimensions.

  • Test plating durability (salt spray test).


6. Efterbehandling & Plating Options

Slutte Effect Cost Addition
High Polish Mirror-like shine +$1–$3
Matte/Satin Blød, non-reflective +$2–$5
Guldbelægning Luxe rose gold/yellow gold +$3–$10
Oxideret Darkened vintage look +$4–$8

7. Kvalitetskontrol & Afprøvning

  • Dimensionel nøjagtighed (caliper measurement)

  • Plettering adhæsionstest (tape peel test)

  • Sær modstand (humidity chamber)


8. Omkostningsfordeling

EN. Materielle omkostninger

Materiale Cost per Unit
925 Sølv (25mm) $6–$15
Messing (Forgyldt) $3–$8
Rustfrit stål $4–$10

B. Arbejdskraft & Production Costs

Metode Cost per Unit
CNC bearbejdning $8–$20
Laserskæring $5–$15
Casting $10–$30
Håndlavet $50- $ 200

C. MOQ Impact on Pricing

Bestilsmængde Price per Unit
1–50 pcs $25–$80
50–200 pcs $15–$40
200–1000 pcs $8–$25
1000+ PCS $5–$15

Total Estimated Cost Range:

  • Masseproduktion (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. Kina: Low-cost, high-volume (MOQ 500+)

  2. Thailand: Handcrafted excellence (MOQ 50+)

  3. Italien: Luxury craftsmanship (MOQ 10+)


11. Casestudie: 500-Unit Production Run

  • Design: Laser-cut sterling silver rose pendant

  • Fabrikant: Guangdong Jewelry Co. (Kina)

  • Koste: $12/enhed ($6,000 total)

  • Timeline: 25 dage (including shipping)


12. Konklusion & Recommendations

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

  • Best for Luxury: CNC-milled 925 sølv

  • Best for Small Batches: Casting + hånd efterbehandling

Næste trin:

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

  2. Request quotes from 3–5 manufacturers.

  3. Bestil prøver before full production.
