Gigacasting / megacasting
New manufacturing technologies such as giga- and megacasting are revolutionising the automotive
industry. Instead of multiple individual parts, complex structural components are now
produced in a single casting. Aluminium alloys are used to manufacture components that are
bigger, more lightweight, yet resilient. These processes promise to reduce weight, boost performance
and help ensure safety in future vehicles.
