Semi-Automatic Vacuum Centrifugal Casting Machine–Solving Irregular-Edge & Thin-Wall Forming Challenges for Zinc Alloy Medals

This semi-automatic vacuum centrifugal casting machine is purpose-built for precision casting of zinc alloy medals, featuring centrifugal force + vacuum negative pressure as its dual driving force—particularly effective in overcoming misruns, flow marks, and deformation issues commonly encountered in irregular edges, thin-wall sections, and sharp corners.

Centrifugal Force Drives Edge Filling–Conquering Irregular Contour Forming

Medals often feature asymmetrical edges, concave curves, and sharp angular transitions—irregular structures that gravity casting struggles to fill completely. This machine uses high-speed centrifugal force to drive molten zinc alloy powerfully toward cavity edges, ensuring one-shot complete replication of irregular contours, eliminating edge misruns and blurred patterns caused by excessive corner radii.

Vacuum System Assists Thin-Wall Filling–Prevents Deformation in Lightweight Medals

Lightweight thin medals are prone to cold shuts and warping due to filling resistance. Equipped with an imported high-vacuum pump, this machine actively evacuates residual mold gases before pouring, significantly reducing flow resistance and ensuring smooth filling of thin-wall sections and tiny lettering—minimizing stress-induced deformation.

Semi-Automatic Design–Flexibly Handles Diverse Irregular Medal Orders

The automatic lid opening/closing design enables quick mold changeover and easy parameter adjustment—ideal for medal customization workshops and event souvenir suppliers handling multi-variety, small-batch, irregular-shaped medal orders. One operator can manage multiple machines, balancing efficiency and flexibility.

With centrifugal force conquering edges and vacuum securing thin walls, your zinc alloy medals achieve breakthrough results in both design and quality.
