Quality Choice for Flawless Zinc Alloy Earrings & Ear Jewelry

This semi-automatic vacuum centrifugal casting machine is purpose-built for zinc alloy earrings, ear studs, ear drops, and ear jewelry accessories, featuring vacuum-assisted degassing and semi-automatic convenient operation. It enables manufacturers to consistently produce high-quality castings with pore-free surfaces, sharp details, and dimensional consistency—even in large-volume orders.

Vacuum System—Eliminates Surface Defects on Ear Jewelry
Earrings demand exceptional surface smoothness, detail sharpness, and pre-plating quality. Equipped with an imported high-vacuum pump, this machine effectively evacuates trapped gases from the mold cavity before pouring, drastically reducing bubbles, pinholes, and oxide inclusions. Each earring casting emerges with a smooth, lustrous metal surface, minimizing post-polishing loss and boosting yield rates.

Semi-Automatic Design—Labor-Saving & Efficient for Batch Earring Production
Compared to manual models, the semi-automatic lid opening/closing design reduces labor intensity and manual intervention, making it ideal for continuous stable production of bulk earring orders. Operators can manage multiple units simultaneously, increasing per-person output and lowering per-piece costs.

Centrifugal Force + Vacuum—Every Detail Revealed
Molten zinc alloy flows smoothly into every tiny cavity feature—including earring post details, clasp mechanisms, and surface textures—driven by both centrifugal force and vacuum negative pressure. The castings are dense, dimensionally accurate, and smooth-surfaced, ready for electroplating or assembly with minimal finishing.

With moderate investment and consistent quality, this machine is the ideal choice for earring brands, OEM factories, and jewelry workshops aiming to enhance product competitiveness.
