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.

Why This Machine Fits Butterfly Brooch Production

表格

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

Ideal For

Butterfly brooches & insect jewelry — delicate wing veins, openwork details
Fashion jewelry pendants — light, wearable, plating-ready
Women's accessory collections — consistent bulk production
Custom designer pieces — reliable reproduction of intricate designs
Gift & souvenir jewelry — repeatable quality at scale

Why Magnesium-Zinc Alloy?

Lightweight — comfortable for daily wear brooches and pendants
Good fluidity — fills thin, delicate jewelry forms cleanly
Skin-friendly — lower allergy risk than standard zinc for direct-contact jewelry
Plating adhesion — takes rhodium, gold, rose gold, and antique finishes evenly

Buyer Takeaway

Fewer rejects from thin-wing breakage or surface pitting
Jewelry-smooth surface ready for direct plating
Light, wearable brooches your customers will love
Easy semi-automatic operation for small jewelry workshops
