Semi-Automatic Spinning Casting Equipment For Zinc Alloy & Magnesium-Zinc Alloy Butterfly Brooch Jewelry Production

Semi-Automatic Spinning Casting Equipment For Zinc Alloy & Magnesium-Zinc Alloy Butterfly Brooch Jewelry Production

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.
