Заключение & Recommendations
1. Introduction to Openwork Jewelry
Openwork (or filigree) jewelry features intricate cut-out designs, making it lightweight yet visually striking. А rose-shaped pendant in this style requires precision manufacturing, typically using:
✔ CNC machining (for sharp, clean edges)
✔ Laser cutting (for delicate patterns)
✔ Инвестиционный кастинг (for organic shapes)
This guide covers how to produce an openwork rose pendant and analyzes cost factors based on materials, труд, and order quantity.
2. Designing the Rose-Shaped Pendant
Key Design Considerations
-
Pattern Complexity (more details = higher cost)
-
Size & Толщина (affects material usage)
-
Attachment Method (bail, jump ring, or integrated chain)
Software Used
-
Атмосфера (Rhino, Matrix, ZBrush) for 3D modeling
-
Vector (Adobe Illustrator) for laser-cut designs
Example Design Specs:
-
Diameter: 25мм
-
Толщина: 1.2мм
-
Материал: 925 серебро 925 пробы
3. Materials Selection
Материал | Pros | Cons | Лучше всего для |
---|---|---|---|
925 серебро 925 пробы | Premium finish, устойчивый к тарнису | Higher cost | High-end jewelry |
Латунь (Gold-Plated) | Доступный, универсальный | May tarnish over time | Модные украшения |
Stainless Steel | Durable, hypoallergenic | Harder to cut finely | Minimalist designs |
4. Manufacturing Methods
4.1 CNC Machining
-
Процесс: A computer-controlled router cuts the design from a metal sheet.
-
Лучше всего для: Precise geometric patterns.
-
Cost: $8–$20 per unit (Могил 50+)
4.2 Лазерная резка
-
Процесс: A laser burns through metal to create intricate designs.
-
Лучше всего для: Ultra-fine details (НАПРИМЕР., petal textures).
-
Cost: $5–$15 per unit (Могил 100+)
4.3 Кастинг (Lost-Wax & 3D Печать)
-
Процесс: Wax model → Plaster mold → Molten metal casting.
-
Лучше всего для: Organic, curved rose shapes.
-
Cost: $10–$30 per unit (Могил 20+)
4.4 Ручное изготовление
-
Процесс: Artisans cut and solder metal wires.
-
Лучше всего для: Custom one-of-a-kind pieces.
-
Cost: $50–$200 per unit (Labor-intensive)
5. Step-by-Step Production Process
Шаг 1: CAD Design & Прототипирование
-
Create a 3D model of the rose pendant.
-
Test print in wax or resin before metal production.
Шаг 2: Metal Cutting/Forming
-
CNC/laser cuts the design from a sterling silver sheet.
-
If casting, inject molten silver into a mold.
Шаг 3: Уборка & Полировка
-
Remove burrs with ultrasonic cleaning.
-
Polish to a mirror or matte finish.
Шаг 4: Покрытие (Необязательный)
-
Gold/Rhodium plating for extra shine.
-
Antique oxidation for vintage effects.
Шаг 5: Качественная проверка
-
Check for defects, weight, and dimensions.
-
Test plating durability (salt spray test).
6. Отделка & Plating Options
Finish | Effect | Cost Addition |
---|---|---|
Высокий лак | Mirror-like shine | +$1–$3 |
Matte/Satin | Soft, non-reflective | +$2–$5 |
Золотое покрытие | Luxe rose gold/yellow gold | +$3–$10 |
Окислен | Darkened vintage look | +$4–$8 |
7. Контроль качества & Testing
-
Точность размеров (caliper measurement)
-
Plating Adhesion Test (tape peel test)
-
Tarnish Resistance (humidity chamber)
8. Cost Breakdown
А. Material Costs
Материал | Cost per Unit |
---|---|
925 Серебро (25мм) | $6–$15 |
Латунь (Gold-Plated) | $3–$8 |
Stainless Steel | $4–$10 |
Беременный. Labor & Production Costs
Method | Cost per Unit |
---|---|
CNC Machining | $8–$20 |
Лазерная резка | $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:
-
Массовое 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.
Best Choice?
-
Startups → ODM (lower design cost)
-
Established brands → OEM (full customization)
10. Top Manufacturers
-
China: Low-cost, high-volume (Могил 500+)
-
Thailand: Handcrafted excellence (Могил 50+)
-
Италия: Luxury craftsmanship (Могил 10+)
11. Тематическое исследование: 500-Unit Production Run
-
Дизайн: Laser-cut sterling silver rose pendant
-
Производитель: Guangdong Jewelry Co. (China)
-
Cost: $12/unit ($6,000 total)
-
Timeline: 25 days (including shipping)
12. Заключение & Recommendations
-
