High-Quality Volume Production Solution for Zinc Alloy Bangles & Bracelets

This semi-automatic vacuum centrifugal casting machine is purpose-built for high-quality volume production of zinc alloy bangles and bracelets in small-to-medium batch quantities, with vacuum-assisted degassing + centrifugal precision filling + semi-automatic stable control as its core advantages—helping jewelry manufacturers achieve porosity-free surfaces, high arc precision, and consistent quality in batch production to meet the fashion accessories market's dual demands for capacity and quality.

Vacuum Degassing–Eliminates Porosity for Superior Polishing & Plating Yield

Bangles and bracelets feature large curved surfaces demanding exceptional surface smoothness. Equipped with a high-vacuum system that actively evacuates residual mold gases before metal filling, it thoroughly eliminates pinholes, gas bubbles, and oxide inclusions—ensuring castings emerge with smooth, refined surfaces immediately upon demolding, providing a perfect substrate for subsequent polishing and electroplating while significantly reducing surface finishing rejection rates.

Centrifugal Uniform Filling–Ensures Wall Thickness Consistency & Arc Precision

The wall thickness uniformity of bangles and bracelets directly affects wearing comfort and product grade. This machine uses high-speed centrifugal force to distribute molten zinc alloy evenly across all cavity sections, ensuring curved surfaces, open ends, and decorative textures fill simultaneously and completely—delivering castings with smooth lines and consistent thickness, significantly reducing post-processing rework.

Semi-Automatic Stable Control–Minimizes Human Variation, Enhances Batch Consistency

Compared to manual models, this machine features semi-automatic lid operation and constant-speed control, reducing quality fluctuations caused by manual differences—ensuring consistent dimensions and appearance across each batch, particularly suitable for small-to-medium batch orders and repeat orders requiring stable delivery.

Rapid Mold Changeover–Flexibly Switch Between Styles

Supports quick mold changes, enabling fast switching between bangles of varying diameters, widths, and textures—improving response efficiency for multi-variety orders.

With vacuum quality + semi-automatic efficiency as your dual assurance, achieve higher yield and faster delivery in batch production of bangles and bracelets.
