Zinc Alloy Metal Brooch with Letter Print | Semi-Automatic Vacuum Centrifugal Casting Machine
Zinc Alloy Metal Brooch with Letter Print | Semi-Automatic Vacuum Centrifugal Casting Machine
The Jewelry Challenge: Delicate Details, Light Weight
Butterfly brooches are jewelry, not industrial parts. They need:
- Thin wings and delicate vein details that reproduce cleanly
- Lightweight feel — no one wants a heavy brooch pulling on fabric
- Smooth surfaces ready for rhodium, gold, or rose-gold plating
- Consistent weight and color across every piece in a collection
Magnesium-zinc alloy is the jewelry industry's answer: lighter than standard zinc, with excellent fluidity and good skin compatibility. But casting it on the wrong machine still causes thin-wing breakage, surface pitting, and inconsistent weight.
Our semi-automatic centrifugal casting equipment is tuned for this exact jewelry-grade process.
Why This Machine Fits Butterfly Brooch Production
| Feature | Jewelry-Grade Benefit |
|---|---|
| Centrifugal precision filling | Thin wing outlines and fine vein details reproduce completely — no broken edges |
| Vacuum degassing | Pore-free surface → smooth plating, no pinholes after rhodium/gold finish |
| Optimized for Mg-Zn alloy | Lighter cast weight, comfortable to wear, good skin-friendly feel |
| Semi-automatic cycle control | Every brooch in a collection has the same weight, size, and surface |
| Stable temperature | Protects alloy composition, keeps plating color consistent |
