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
