1. Introduction to Openwork Jewelry

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

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

2. Designing the Rose-Shaped Pendant

Key Design Considerations

  • Pattern Complexity (more details = higher cost)

  • Size & Дебелина (affects material usage)

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

Software Used

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

  • Vector (Adobe Illustrator) for laser-cut designs

Example Design Specs:

  • Diameter: 25мм

  • Дебелина: 1.2мм

  • Материал: 925 Стерлинг сребро

3. Materials Selection

Материал Pros Cons Най -доброто за
925 Стерлинг сребро Premium finish, устойчив на лента Higher cost High-end jewelry
Месинг (Gold-Plated) Достъпно, универсален May tarnish over time Модни бижута
Stainless Steel Траен, Хипоалерген Harder to cut finely Minimalist designs

4. Manufacturing Methods

4.1 CNC Machining

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

  • Най -доброто за: Precise geometric patterns.

  • Разходи: $8–$20 per unit (Moq 50+)

4.2 Лазерно рязане

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

  • Най -доброто за: Ultra-fine details (e.g., petal textures).

  • Разходи: $5–$15 per unit (Moq 100+)

4.3 Кастинг (Lost-Wax & 3D Печата)

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

  • Най -доброто за: Organic, curved rose shapes.

  • Разходи: $10–$30 per unit (Moq 20+)

4.4 Изработка на ръце

  • Процес: Artisans cut and solder metal wires.

  • Най -доброто за: Custom one-of-a-kind pieces.

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

5. Step-by-Step Production Process

Стъпка 1: CAD Design & Прототипиране

  • Create a 3D model of the rose pendant.

  • Test print in wax or resin before metal production.

Стъпка 2: Metal Cutting/Forming

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

  • If casting, inject molten silver into a mold.

Стъпка 3: Почистване & Полиране

  • Remove burrs with ultrasonic cleaning.

  • Polish to a mirror or matte finish.

Стъпка 4: Покритие (Незадължително)

  • Gold/Rhodium plating for extra shine.

  • Antique oxidation for vintage effects.

Стъпка 5: Проверка на качеството

  • Check for defects, weight, and dimensions.

  • Test plating durability (salt spray test).

6. Довършителни работи & Plating Options

Завършете Effect Cost Addition
Висок лак Mirror-like shine +$1–$3
Matte/Satin Soft, non-reflective +$2–$5
Златно покритие Luxe rose gold/yellow gold +$3–$10
Окислени Darkened vintage look +$4–$8

7. Контрол на качеството & Testing

  • Размерна точност (caliper measurement)

  • Plating Adhesion Test (tape peel test)

  • Tarnish Resistance (humidity chamber)

8. Cost Breakdown

A. Материални разходи

Материал Cost per Unit
925 Сребро (25мм) $6–$15
Месинг (Gold-Plated) $3–$8
Stainless Steel $4–$10

Б. Труд & Production Costs

Method Cost per Unit
CNC Machining $8–$20
Лазерно рязане $5–$15
Кастинг $10–$30
Handmade $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+ pcs $5–$15

Total Estimated Cost Range:

  • Масово производство (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.

Най -добър избор?

  • Startups → ODM (lower design cost)

  • Established brands → OEM (full customization)

10. Top Manufacturers

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

  2. Thailand: Handcrafted excellence (Moq 50+)

  3. Italy: Luxury craftsmanship (Moq 10+)

11. Case Study: 500-Unit Production Run

  • Design: Laser-cut sterling silver rose pendant

  • Производител: Guangdong Jewelry Co. (Китай)

  • Разходи: $12/unit ($6,000 total)

  • Timeline: 25 дни (including shipping)

12. Заключение & Препоръки

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

  • Best for Luxury: CNC-milled 925 сребро

  • Best for Small Batches: Кастинг + hand-finishing

Next Steps:

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

  2. Заявка оферти from 3–5 manufacturers.

  3. Проби от поръчка before full production.
