Giga Press are a series of
aluminium die
casting machines manufactured by Idra Group in Italy. They are notable for being the largest
high-pressure die casting machines in the world, with a clamping force of 55,000 to 61,000 kilonewtons (5,600 to 6,200 tf). Initial usage of a customised
OL 6100 CS Giga Press was started by
Tesla, Inc. in late-2020 with production of the
Tesla Model Y electric car rear
chassis, at the
Tesla Factory in Fremont, California.
Base specification
OL 5500 CS and
OL 6200 CS Giga Press machines had been included in Idra's catalogue since 2018. Each machine weighs 410–430 tonnes (900,000–950,000 lb).
Shots of molten aluminium weighing 80 kilograms (180 lb) are injected into the cold-chamber
casting mold with a velocity of 10 metres per second (22 mph; 36 km/h).
The cycle time is ~80‒90 seconds, allowing an output rate of 40‒45 completed castings per hour, or ~1,000 castings per day.
