Two Easy Steps

1. a fast discharge of electrical current rapidly heats the metallic glass feedstock. processing takes place at viscosities of 100 to 10,000 Pa.s.

2. a deformational force or pressure is applied to shape and form the metal into a net shape component.

Production Cycle Breakdown


Follow along



An amorphous metal feedstock is loaded into a barrel connected to the mold cavity. The mold is closed and a clamping force (Fm) is applied. The feedstock makes electrical contact with two electrodes that approach it axially on either end. This contact is maintained by application of contact force (Fc).


The electrodes are connected to a capacitor bank storing sufficient energy to bring the feedstock to its processing temperature. A high current, with a peak between 10 to 20 kA, is discharged through the feedstock heating the material to its processing temperature in 20-30 ms. 


One electrode - also serving as a plunger - drives the softened metal through a gate and into the mold cavity. The entire injection process takes place in 50-100 ms. 


Once the injection stroke is complete, a packing force (Fp) is maintained by the plunger as the material cools in the mold. The time required for cooling depends on part geometry but varies between 500 ms to 5 s. 


Once the parts have cooled, the mold is opened and the parts are ejected. 



Subsequently, the electrodes are repositioned to accept a new feedstock. The capacitor bank is recharged for the next molding cycle.
