Engineering the
Liquidmetal Process

Once the Liquidmetal alloy is produced, it is broken down into small, gravel-like particles before entering the molding equipment. Since the alloying stage does not control the cooling rate, the material ends up in a crystalline form when received.

The alloy is melted inside a vacuum chamber using an induction heating coil. Each batch is precisely pre-measured so that only the exact amount required to fill the tool’s cavities is liquefied.

This image shows the mold opened after the parts have cooled. The central injection point is connected to runners that routed the molten alloy into four individual cavities to form the components.

The mold is engineered so that the parts remain on a designated side when it opens. Ejector pins then activate to help a robotic arm extract the parts, which are still attached to the leftover injection port and runner system.

Because Liquidmetal reaches its final physical properties as soon as it cools in the mold, the part cannot be separated from the runner system during ejection as it would be in conventional molding. Instead, a secondary operation—such as laser cutting or water-jet removal—is required to detach the part.
