Semi-Automatic Vacuum Centrifugal Casting Machine–Ensuring Synchronized Perfect Forming of Front & Back Details on Zinc Alloy Medals

This semi-automatic vacuum centrifugal casting machine is purpose-built for precision casting of zinc alloy medals, with uniform centrifugal filling + vacuum-assisted degassing as its core advantages—ensuring that front relief details and backside lettering, LOGOs, and clasp structures achieve complete, dense forming simultaneously, eliminating the common problem of inconsistent front-to-back quality.

Uniform Centrifugal Distribution–Synchronized Full Filling on Both Sides

Medals feature fine front relief while the back often carries inscriptions, brand LOGOs, pin clasps, or magnetic attachments—with significant differences in thickness and structure between the two sides, often resulting in “one side full, the other side misrun.” This machine uses high-speed centrifugal force to distribute molten zinc alloy evenly across all cavity regions, ensuring both front and back receive adequate filling pressure simultaneously—structurally eliminating front-to-back quality imbalance.

Vacuum-Assisted Degassing–Ensures Complete, Sharp Backside Lettering

Backside lettering and LOGOs typically feature fine strokes and deep recesses, where residual mold gases easily obstruct filling, causing incomplete strokes and blurred edges. Equipped with an imported high-vacuum pump, this machine actively evacuates mold gases before pouring, allowing melt to flow smoothly into the deepest recesses—ensuring every stroke and letter edge remains complete and sharp.

Semi-Automatic Design–One Operator, Multiple Machines–Efficiency & Quality Balanced

The automatic lid opening/closing design reduces labor intensity and enables quick mold changes—ideal for medal customization workshops and event souvenir suppliers handling multi-variety, small-batch orders. One operator can manage multiple units, boosting output while maintaining consistent double-side quality.

With centrifugal uniformity + vacuum precision, your zinc alloy medals achieve excellent quality on both front and back.
