Net shape in one step

Process overview
Final properties out of the mold

The amorphous metal process yields complex, metal parts with final net-shape in a single molding step. This step involves melting, injecting, and removing the cooled Liquidmetal alloy from the mold cavity.

Gate and runner removal

Once parts have been injection molded, they are ready to use except for removing gates and runners. To remove gates and runners, there are a few suitable approaches depending on the requirements of the finished part. If slight gate vestige is acceptable, waterjet cutting can be used. In cases where little or no gate witness is desired, CNC machining can be employed to remove the gate and runner system.

Post processing

A wide array of post-processing alternatives are available for amorphous metal parts should you want to achieve specific results outside of the basic requirement to de-gate parts after molding. Some of the more commonly applied post-processing techniques include bead and media blasting, machining, laser welding and e-beam joining, painting, gluing, and physical vapor deposition (PVD).

THE PROCESS

01

Load material

Crystalline ingots are loaded into the ENGEL e-motion 110 Liquidmetal edition molding machine or a custom fitted Liquidmetal die casting machine.

02

Melt

After automatic loading, Liquidmetal alloy is melted using an induction heating system, reaching temperatures up to 1000°C.

03

Inject

Once the alloy is fully viscous following the 1-2 minute melt period, it is injected into the mold.

04

Molded parts

Moments after injection, Liquidmetal alloy freezes in the mold, forming a net-shape part. This fully amorphous, cool to the touch Liquidmetal part tree is ejected from the mold and ready for de-gating.

05

Waterjet gate and runner removal

The waterjet provides a rough and quick cut of the gate and runner system from the Liquidmetal part tree.

06

Finishing touches

Machining offers the ability to remove final gate and runner evidence, and also generate additional features that may not be possible with the Liquidmetal molding process.
