Summary:An injection device and method for producing at least one metallic glass part, in which a vertical piston is able to move in a vertical direction, a top end portion of the piston being suitable for being engaged in an injection chamber of a mould linked to a cavity of this mould and open at the bottom; the piston having a top end face on which an element made from metallic glass to be introduced into said chamber can be positioned, the top face of the piston having a concave shape suitable for receiving a bottom portion of the element made from metallic glass. A heating means situated under the mould comprises induction coils, such that, when the piston is in an intermediate position, the majority of the metallic element is situated in the space surrounded by the induction coils.
