With over 40 years of operation producing well over a billion pounds of Aluminum the Golden Aluminum Block Caster is by far the most successful block caster in the world. The block caster uses tracks of copper coated steel blocks on tracks to cool and solidify the aluminum into a sheet. The block concept was a breakthrough in thinking vs previous belt concepts as the blocks had the thermal mass and rigidity to produce a sheet of consistent structure while running at a relatively high speed.
