Porosity or Defective Castings? This Semi-Auto Vacuum Centrifugal Machine Gives You Clean, Detailed Medals Every Time

For medal and badge manufacturers, the biggest headache isn’t design—it’s porosity, sand holes, and incomplete filling after casting. These defects drive up scrap rates, force rework, and eat into your margins.

The root cause is often trapped air during pouring, preventing molten metal from fully filling fine details. Traditional manual machines make things worse with inconsistent speed control and time-consuming door operations.

Our semi-automatic vacuum centrifugal casting machine solves these problems at the source:

• Auto door open/close–Operators only need to load and unload molds; the machine handles the rest, reducing manual effort and improving batch consistency.

• Built-in vacuum system–Maintains a vacuum throughout the entire casting cycle, ensuring flawless metal flow into every fine line. The result: sharper, more 3D details on medals and badges, with significantly fewer porosity and sand hole defects.

• Intelligent control panel–Precise rotation adjustment, with digital display, and mechanical gauges for easy monitoring—even new operators can achieve professional results.

• Extended mould life–Vacuum casting minimizes thermal shock and oxidation wear on molds, so they last much longer, saving you replacement costs over time.

In short, you just place and remove the molds—the machine does the heavy lifting. Fewer rejects, happier customers, and higher throughput—that’s how you stay competitive.
