One aspect relates to an injection molding system for the injection molding of amorphous metals, an injection molding unit for the injection molding of amorphous metals and an injection molding process for amorphous metals.

The injection molding system includes a channel for feeding a molten metal and a slider unit including a slider and a pressure system. The slider is located between the channel and at least one injection molding cavity and is movable between a rest position and an injection position. In the rest position, the slider blocks the access of the molten metal to the injection molding cavity and in the injection position it allows the molten metal to access the injection molding cavity. The pressure system holds the slider in the rest position and allows the slider to move to the injection position when a minimum pressure is exceeded.
