Semi-Automatic Three-Die-Head Centrifugal Casting Machine for Producing Metal Zamak Alphabet-Themed Commemorative Badges and Brooches

Semi-Automatic Three-Die-Head Centrifugal Casting Machine for Producing Metal Zamak Alphabet-Themed Commemorative Badges and Brooches

Product Overview

This semi-automatic three-die-head centrifugal casting machine is purpose-built for producing Zamak alphabet-themed commemorative badges and brooches. The three-die-head rotary design enables continuous cycling—casting, cooling, and demolding in rotation—while the variable-frequency centrifugal drive ensures molten Zamak fills every letter stroke, emblem edge, and pin-back detail with precision. With an optional vacuum-assisted degassing system, it delivers clean, porosity-free badge surfaces ready for direct polishing and electroplating.

Key Advantages

1. Three-Die-Head Rotary Table: Continuous Output for Badge and Brooch Batches

The three-die-head design keeps production moving without idle gaps. While one die is spinning and cooling, the operator can load the next die or remove finished pieces from the previous cycle. Output reaches up to 200 casting cycles per hour under continuous operation. For alphabet-themed badge and brooch runs—where multiple letter and emblem designs are often produced in parallel—this rotary format lets you queue different dies back-to-back with minimal changeover downtime.

2. Sharp Letter and Emblem Definition Under Centrifugal Force

Commemorative badges and brooches live or die by detail clarity. The machine's variable-frequency drive maintains stable rotation across 50–1400 rpm, generating consistent centrifugal force that drives molten Zamak into the narrowest letter strokes, fine emblem lines, and raised borders. The result is crisp, fully formed lettering and emblem details straight out of the die—no blurring, no incomplete strokes, no hand rework on text or edge details.

3. Vacuum-Assisted Degassing for Plating-Ready Surfaces

Badges and brooches typically go through electroplating or high-polish finishing, and any surface porosity becomes a visible defect after plating. The vacuum system evacuates residual die gases before pouring, eliminating pinholes and micro-porosity that would otherwise show up as pits or plating flaws. This directly improves plating yield and reduces rejection rates on finished badges and brooches.

4. Semi-Automatic Design for Flexible Batch Production

Automatic lid opening and closing reduces operator fatigue during long shifts, while digital speed display and timer settings allow repeatable parameters across different dies and badge sizes. One operator can manage the three-die-head cycle efficiently—ideal for customization workshops handling multiple alphabet and emblem designs in small-to-medium batches. The electronic emergency brake provides immediate safe stops when needed.

5. Optimized for Zamak Badge and Brooch Production

Zamak (zinc alloy) is the standard material for decorative badges and brooches due to its excellent castability, detail reproduction, and plating compatibility. With a pressure regulation range of 0–7 kg and die compatibility up to 12 inches, the machine accommodates common badge and brooch die configurations. The 1.5 kW motor keeps operating costs manageable for small and mid-sized production studios.
