A cold-chamber die-casting apparatus and method for making a die-cast part with an open space within the geometry of the part. The apparatus includes an injection shaft which receives molten material for casting the part. The molten material is pushed with a plunger through a gate and into a tool cavity corresponding to the part. The gate is disposed at an end of the injection shaft and adjacent the tool cavity at a position that corresponds to the open space of the part and is inside the geometry of the part.
