1. Introduction to Openwork Jewelry

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

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

2. Designing the Rose-Shaped Pendant

Key Design Considerations

  • Pattern Complexity (more details = higher cost)

  • مقاس & Thickness (affects material usage)

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

Software Used

  • CAD (وحيد القرن, Matrix, ZBrush) for 3D modeling

  • Vector (Adobe Illustrator) for laser-cut designs

Example Design Specs:

  • Diameter: 25مم

  • Thickness: 1.2مم

  • مادة: 925 الفضة الاسترليني

3. Materials Selection

مادة Pros Cons الأفضل ل
925 الفضة الاسترليني Premium finish, مقاوم تشويه Higher cost High-end jewelry
النحاس (Gold-Plated) بسعر معقول, متنوع القدرات May tarnish over time مجوهرات الأزياء
الفولاذ المقاوم للصدأ Durable, hypoallergenic Harder to cut finely تصميمات الحد الأدنى

4. Manufacturing Methods

4.1 CNC Machining

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

  • الأفضل ل: Precise geometric patterns.

  • يكلف: $8–$20 per unit (مو 50+)

4.2 قطع الليزر

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

  • الأفضل ل: Ultra-fine details (على سبيل المثال, petal textures).

  • يكلف: $5–$15 per unit (مو 100+)

4.3 صب (Lost-Wax & 3D Printing)

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

  • الأفضل ل: Organic, curved rose shapes.

  • يكلف: $10–$30 per unit (مو 20+)

4.4 تصنيع اليد

  • عملية: Artisans cut and solder metal wires.

  • الأفضل ل: Custom one-of-a-kind pieces.

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

5. Step-by-Step Production Process

خطوة 1: CAD Design & النماذج الأولية

  • Create a 3D model of the rose pendant.

  • Test print in wax or resin before metal production.

خطوة 2: Metal Cutting/Forming

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

  • If casting, inject molten silver into a mold.

خطوة 3: Cleaning & تلميع

  • Remove burrs with ultrasonic cleaning.

  • Polish to a mirror or matte finish.

خطوة 4: تصفيح (خياري)

  • Gold/Rhodium plating for extra shine.

  • Antique oxidation for vintage effects.

خطوة 5: فحص الجودة

  • Check for defects, وزن, and dimensions.

  • Test plating durability (salt spray test).

6. الانتهاء & Plating Options

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

7. ضبط الجودة & Testing

  • Dimensional Accuracy (caliper measurement)

  • Plating Adhesion Test (tape peel test)

  • Tarnish Resistance (humidity chamber)

8. Cost Breakdown

أ. Material Costs

مادة التكلفة لكل وحدة
925 فضي (25مم) $6–$15
النحاس (Gold-Plated) $3–$8
الفولاذ المقاوم للصدأ $4–$10

ب. تَعَب & Production Costs

Method التكلفة لكل وحدة
CNC Machining $8–$20
قطع الليزر $5–$15
صب $10–$30
مصنوعة يدويا $50–$200

ج. 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:

  • إنتاج متسلسل (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. الصين: Low-cost, high-volume (مو 500+)

  2. Thailand: Handcrafted excellence (مو 50+)

  3. إيطاليا: Luxury craftsmanship (مو 10+)

11. دراسة حالة: 500-Unit Production Run

  • تصميم: Laser-cut sterling silver rose pendant

  • الشركة المصنعة: Guangdong Jewelry Co. (الصين)

  • يكلف: $12/unit ($6,000 total)

  • Timeline: 25 أيام (including shipping)

12. خاتمة & Recommendations

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

  • Best for Luxury: CNC-milled 925 فضي

  • Best for Small Batches: صب + hand-finishing

Next Steps:

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

  2. Request quotes from 3–5 manufacturers.

  3. Order samples قبل الإنتاج الكامل.
