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

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


This semi-automatic vacuum centrifugal casting machine is designed for producing zinc alloy metal brooches with letter prints, personalized logos, and decorative patterns. By combining vacuum technology with centrifugal force, the machine helps improve molten metal filling, reproduce fine lettering and intricate details, and reduce air bubbles and casting defects. It is suitable for manufacturing customized name badges, alphabet brooches, logo pins, and fashion accessories. With convenient operation and adjustable casting parameters, this equipment is an ideal choice for metal craft manufacturers looking to improve product consistency, casting quality, and production efficiency.
