Product Description

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
