Semi-automatic Spin Casting Machine for Women's Fashion Zinc Alloy Bracelet Jewelry Elegant Bracelet Making Machine

High-Efficiency Precision Casting Solution for Zinc Alloy Bangles & Bracelets

This semi-automatic vacuum centrifugal casting machine is purpose-built for high-efficiency precision casting of zinc alloy bangles and bracelets in small-to-medium batch production, with vacuum-assisted degassing + centrifugal precision filling + semi-automatic convenient operation as its core advantages—helping jewelry manufacturers consistently produce high-quality bangles and bracelets with flawless surfaces, smooth curves, and consistent dimensions to meet the dual demands of the fashion accessories market for quality stability and production efficiency.

Semi-Automatic Convenient Operation–Reduces Labor Intensity, Boosts Batch Production Efficiency

This machine features a semi-automatic lid opening/closing design that significantly reduces manual workload while retaining flexible adjustment capability. Operators simply set speed and timing parameters—the machine automatically handles lid control, speed regulation, and timing. One operator can manage multiple units, effectively increasing per-person output. Compared to manual models, efficiency is significantly improved, making it especially suitable for small-to-medium batch orders with fast turnaround requirements.

Vacuum-Assisted Degassing–Ensures Flawless Large Curved Surfaces

Bangles and bracelets feature large curved surfaces—where even minor porosity compromises polishing and plating results. Equipped with an imported high-vacuum pump that actively evacuates residual mold gases before pouring, fundamentally eliminating pinholes, gas porosity, and surface pits—producing castings with smooth, refined metal surfaces immediately upon demolding, providing a perfect substrate for subsequent polishing, electroplating, and sandblasting—effectively improving surface treatment yield.

Centrifugal Precision Filling–Accurately Reproduces Curved Lines & Decorative Details

This machine uses high-speed centrifugal force to distribute molten zinc alloy uniformly into every fine cavity detail, ensuring the melt tightly conforms to the curved mold surface—precisely reproducing arc contours, opening shapes, surface textures, and decorative lines. Castings deliver smooth lines and uniform wall thickness—significantly reducing manual finishing operations.

Rapid Mold Changeover—Easily Switch Between Sizes & Designs

Supports quick mold changes, enabling fast switching between bangles of varying diameters, widths, and designs—maximizing overall equipment utilization.

With semi-automatic efficiency + vacuum quality as your dual drivers, achieve simultaneous gains in quality and efficiency in batch production of bangles and bracelets.
