1. Introduction to Openwork Jewelry

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

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


2. Designing the Rose-Shaped Pendant

Key Design Considerations

  • Pattern Complexity (more details = higher cost)

  • Size & 두께 (affects material usage)

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

Software Used

  • 치사한 사람 (Rhino, Matrix, ZBrush) for 3D modeling

  • Vector (Adobe Illustrator) for laser-cut designs

Example Design Specs:

  • Diameter: 25mm

  • 두께: 1.2mm

  • Material: 925 스털링 실버


3. Materials Selection

Material 프로 단점 가장 좋습니다
925 스털링 실버 Premium finish, tarnish-resistant Higher cost High-end jewelry
놋쇠 (Gold-Plated) Affordable, versatile May tarnish over time Fashion jewelry
Stainless Steel Durable, hypoallergenic Harder to cut finely Minimalist designs

4. Manufacturing Methods

4.1 CNC Machining

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

  • 가장 좋습니다: Precise geometric patterns.

  • 비용: $8–$20 per unit (모크 50+)

4.2 Laser Cutting

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

  • 가장 좋습니다: Ultra-fine details (예를 들어, petal textures).

  • 비용: $5–$15 per unit (모크 100+)

4.3 주조 (Lost-Wax & 3D Printing)

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

  • 가장 좋습니다: Organic, curved rose shapes.

  • 비용: $10–$30 per unit (모크 20+)

4.4 Hand Fabrication

  • Process: Artisans cut and solder metal wires.

  • 가장 좋습니다: Custom one-of-a-kind pieces.

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


5. Step-by-Step Production Process

단계 1: CAD Design & 프로토 타이핑

  • Create a 3D model of the rose pendant.

  • Test print in wax or resin before metal production.

단계 2: Metal Cutting/Forming

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

  • If casting, inject molten silver into a mold.

단계 3: 청소 & 세련

  • Remove burrs with ultrasonic cleaning.

  • Polish to a mirror or matte finish.

단계 4: 도금 (선택 과목)

  • Gold/Rhodium plating for extra shine.

  • Antique oxidation for vintage effects.

단계 5: 품질 검사

  • Check for defects, 무게, and dimensions.

  • Test plating durability (salt spray test).


6. 마무리 손질 & Plating Options

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

7. 품질 관리 & Testing

  • Dimensional Accuracy (caliper measurement)

  • Plating Adhesion Test (tape peel test)

  • 변색 저항 (humidity chamber)


8. Cost Breakdown

에이. 재료 비용

Material Cost per Unit
925 은 (25mm) $6–$15
놋쇠 (Gold-Plated) $3–$8
Stainless Steel $4–$10

B. 노동 & Production Costs

Method Cost per Unit
CNC Machining $8–$20
Laser Cutting $5–$15
주조 $10–$30
수공 $50- $ 200

기음. 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+ pcs $5–$15

Total Estimated Cost Range:

  • 양산 (1000+): $10–$25/unit

  • Small Batch (50–100): $20–$50/unit

  • Custom Handmade: $80–$300/unit


9. OEM 대. 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. 중국: Low-cost, high-volume (모크 500+)

  2. Thailand: Handcrafted excellence (모크 50+)

  3. Italy: Luxury craftsmanship (모크 10+)


11. 사례 연구: 500-Unit Production Run

  • 설계: Laser-cut sterling silver rose pendant

  • Manufacturer: Guangdong Jewelry Co. (중국)

  • 비용: $12/unit ($6,000 total)

  • Timeline: 25 days (including shipping)


12. 결론 & Recommendations

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

  • Best for Luxury: CNC-milled 925 은

  • Best for Small Batches: 주조 + 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.
