1. Why Choose 925 Silver for Custom Heart Pendant Earrings?
Advantages of 925 Sterling Silver
✔ Hypoallergenic – Safe for sensitive skin
✔ Luxurious Appearance – Bright, polished finish
✔ Durable Yet Malleable – Ideal for intricate designs
✔ Better Engraving Clarity – Softer than stainless steel, crisper than brass
Why CNC Engraving Beats Laser/Hand Engraving
- Higher precision (up to 0.01mm accuracy)
- Deeper, longer-lasting engravings
- Consistent results across mass production
2. Understanding CNC Engraving Technology for Jewelry
How CNC Machines Work
- Computer-controlled rotary tools carve logos into metal
- Uses diamond or tungsten carbide bits for clean cuts
- Works with 3D CAD files (vector-based designs preferred)
Types of CNC Engraving for Jewelry
| Type | Best For | Depth | Finish |
|---|---|---|---|
| Line Engraving | Thin logos, text | 0.1-0.3mm | Matte texture |
| 3D Relief Engraving | Detailed emblems | 0.5-1mm | Sculpted effect |
| Micro Engraving | Tiny barcodes, serial numbers | <0.1mm | Nearly invisible |
3. Step-by-Step Process: From CAD Design to Finished Product
Step 1: Logo Design Preparation
- Vector file (AI, EPS, DXF) required (no pixelated images)
- Minimum line thickness: 0.2mm (for readability)
- Avoid overly complex designs (simpler = cleaner engraving)
Step 2: CAD Modeling & CNC Toolpathing
- JINGYING’s engineers convert your logo into a 3D toolpath
- Test engraving on wax/silver sample before full production
Step 3: CNC Engraving Execution
- 925 silver blanks are secured in the CNC machine
- High-speed spindle (20,000-50,000 RPM) carves the logo
- Deburring & polishing removes rough edges
Step 4: Post-Processing
- Polishing (mirror or matte finish)
- Optional gold/rhodium plating
- Oxidization for vintage looks
4. Logo Design Considerations for CNC Engraving
Best Practices
✅ Use bold, simple fonts (avoid serifs under 1mm)
✅ Minimum logo size: 3mm x 3mm
✅ Vector-based artwork only (no JPG/PNG)
Common Mistakes to Avoid
❌ Overly intricate details (may blur during engraving)
❌ Text smaller than 1mm height
❌ Low-contrast designs (hard to read post-engraving)
5. Quality Control & Durability Testing
JINGYING’s QC Process
✔ Microscope inspection (20x magnification)
✔ Salt spray test (for plated items)
✔ Wear simulation (checks engraving longevity)
How Long Will CNC-Engraved Logos Last?
- Unplated silver: 10+ years with proper care
- Gold-plated: 2-5 years (depending on thickness)
- Rhodium-plated: 5+ years (high scratch resistance)
6. Finishing Options for Branded Heart Earrings
| Finish | Appearance | Best For |
|---|---|---|
| Mirror Polish | High-shine luxury | High-end brands |
| Matte Brushed | Subtle, modern | Minimalist designs |
| Gold Plated | Warm, rich tone | Bridal/luxury markets |
| Oxidized Black | Vintage, gothic | Alternative fashion |
