Semi-Automatic Vacuum Centrifugal Casting Machine–Ideal Equipment for Zinc Alloy Medals

This semi-automatic vacuum centrifugal casting machine is purpose-built for fine casting of zinc alloy medals, with vacuum degassing + centrifugal force as its core advantages. It is especially suited for medals featuring delicate 3D relief, slender lettering, and high surface finish requirements—helping manufacturers achieve high-quality castings with flexible small-batch production.

Vacuum Degassing–Eliminates Porosity Defects at the Source, Ensures Pattern Fidelity

Medals often feature fine relief patterns, tiny lettering, geometric rims, and decorative textures, demanding high internal quality and surface smoothness. Equipped with an imported high-vacuum pump, this machine actively evacuates residual mold gases before pouring, effectively eliminating porosity, pinholes, and oxide inclusions. Castings emerge with clear, complete patterns, reducing rework and improving first-pass yield.

Centrifugal Filling–Ensures Full, Sharp Reproduction of Complex Patterns

Under high-speed centrifugal force, molten zinc alloy is driven evenly and powerfully into every cavity detail—including recessed textures, raised relief, sharp edges, and backside lettering. Centrifugal action ensures the melt conforms tightly to the cavity surface, delivering high detail fidelity and minimizing flow marks and misruns—even with varying wall thicknesses.

Semi-Automatic Design–Flexible & Efficient for Small-Batch Multi-Variety Medal Orders

The semi-automatic lid opening/closing design reduces labor intensity, allowing one operator to manage multiple units—ideal for medal customization workshops and event souvenir suppliers handling diverse, small-batch orders. Quick mold changeover and easy parameter adjustments ensure seamless transition from sampling to production.

With vacuum quality + centrifugal detail as your dual assurance, your zinc alloy medals will earn customer recognition for both quality and appearance.
