The Italian company will supply Tesla with a 5,500-ton press, suggestively called Giga Press.

When Sandy Munro revealed the biggest Model Y secret – its cast parts – he said a single piece would replace the two halves that it currently uses. According to SAE, that is close to becoming a reality thanks to the IDRA Group. This Italian machinery company is the supplier of the casting equipment Tesla uses, and it says these machines are called Giga Presses. Suggestive, right?

After reading SAE's Automotive Engineering article, we got more details about what these casting machines. The article mentions Tesla uses an OL 6100 CS press, but the IDRA website contradicts that information. There is no OL 6100 CS, according to the official data, only an OL 6200 CS HPDC – High-Pressure Die Casting.

Tesla ordered an OL 5500 CS HPDC, which is mistakenly considered to weight 5,500 tons in an article the company quotes to tell the world it is Tesla's supplier – 5,500 tons is the clamping force this press has, not its mass.

SAE's article mentions the machine is 64 feet (19.5 m) long, 17 feet (5.3 m) tall, and that it weighs 410 tons. It also has "a maximum aluminum-alloy 'shot' weight of 104.6 kg (231 lbs)," but that information relates to the OS 6200 CS HPDC. Which actually weighs 430 tons.

The OL 5500 CS HPDC is 63 feet (19.2 m) long, 17.1 feet (5.22 m) tall, and 22.6 feet (6.9 m) wide. Curiously, it is wider than the OL 6200 CS HPDC, which is 19.4 feet (5.9 m) wide. Its maximum aluminum-alloy shot weight is 84 kg (185.2 lbs) apart from the 5,500 tons clamping force, and it has a mass of 410 tons. Like Elon Musk said, it is as big as a house.

SAE also states these Giga Presses will be used in Fremont and Shanghai. Considering Lathrop also makes cast parts, we thought the Giga Press for the Model Y was placed there, but that does not seem to be the case.

The Giga Presses are part of the OL CS machine family, which has much smaller presses. In an attempt to show how big the Giga Presses are, the IDRA Group used the image of the OL 1900 CS HPDC, as you can see below. Don't miss the chance to visit the page dedicated to it and to play with the 360º view of these casting machines.

The OL 1900 CS HPDC is much smaller, with a length of 38.4 feet (11.7 m), a height of 14.4 feet (4.4 m), and a width of 13.8 feet (4.2 m). The clamping force it offers (1,900 tons) already shows it presents a much lower scale, but its maximum Al-alloy shot weight – 28 kg, or 61.7 lbs – and total mass – 98 tons – make us understand why the company does not have an image of the real thing to present. It is probably something so unique that it only exists inside a Tesla facility. We would not doubt if there was an NDA involved with the business.

It is a pity Sandy Munro will not tear down another Model Y. If that were the case, we would probably be warned about this new single cast part by him. Our best odds apart from that are Elon Musk tweets

Will the Tesla CEO warn us there when the Model 3 also receives this new casting? Or about the single cast part for the Model Y's front structure? We have no idea. What we know for sure, thanks to SAE and IDRA Group, is that Tesla has already bought the machinery necessary to get there.
