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).[2][3]

Base specification Giga Press machines had been included in Idra's catalogue since 2018,[4] with usage of a customized Giga Press started by Tesla, Inc. in late-2020 for the production of chassis parts for the Tesla Model Y.[5]

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).[6] The cycle time is ~80‒90 seconds,[2] allowing an output rate of 40‒45 completed castings per hour, or ~1,000 castings per day.

As of 2015 Idra was one of the ten most important strategic suppliers to Tesla Motors,[7] with Tesla using purely die-casting machines made by Idra for use at the factories in California.[8][9] In 2016 Tesla ordered a 3,000-tonne-force (30,000 kN; 7,000,000 lbf) press from Idra for making major car chassis components.[10]

In 2019 Jerome Guillen stated that Tesla Grohmann Automation were working on a "giant, giant, giant machine" to "make full-size cars in the same way that toy cars are made".[11]

With our giant casting machines, we are literally trying to make full-size cars in the same way that toy cars are made

Elon Musk, (18 January 2021)[12]

In April 2020, Elon Musk stated that the two biggest casting machines in the world had been purchased to enable casting the Tesla Model Y rear chassis and crash rails as a single component.[13][14] By November 2020, three OL 6100 CS machines had been built in Italy; one was under construction and seven more had been ordered.[15]

By the end of 2020, another eleven machines had been ordered.[16]

In January 2021, Elon Musk announced that the rear chassis of the Tesla Cybertruck would be produced using an over-8,000-tonne-force (80,000 kN) casting machine.[17]

Deployment

Vacuum inside the closed mould is achieved using a 4,000-litre tank made by Fondarex in Switzerland.[18]

Molten metal is pumped through heated pipes, and rotary degassing is performed to reduce porosity in the casting.[19]

As of June 2020 Tesla planned additional machinery to support each 6,100-tonne-force (60,000 kN) Giga Press operation:[20]: 83‒86 

  1. Melt oven (850 °C, 1,560 °F)
  2. Holding oven (~750–850 °C, 1,380–1,560 °F)
  3. Giga Press ("DCM"‒Die-casting Machine)
  4. Quench oil Tank
  5. Mechanical Trim Press
  6. X-Ray machine (porosity check)
  7. Laser Trim
  8. Drill and Tap (machining)
  9. Laser Scanning (coordinate-measuring machine, CMM)
  10. Fasteners insertion
  11. Scrap metal shredder (immediate closed loop recycling of aluminium offcuts)
  12. Vacuum system

Fremont

Preparation work for installation of the first Giga Press die casting machine ("DCM1")[f 1] was planned to begin in California during May 2020.[13] In May 2020, Tesla requested building permits from the City of Fremont for demolishing a car wash at the Tesla Factory, and installing an arch-shaped metal building for casting machinery.[f 2][f 3][f 4] During May/June 2020 Tesla advertised a "Castings Tooling & Process Engineer" job, based at the Tesla Factory in Fremont, responsible for production ramp-up of the first Giga Press.[21] In June 2020, permits for foundations to support the Giga Press at Fremont were filed, then issued on 26 June 2020.[f 5][f 6]

During July 2020, relocation of electrical equipment and raising of a compressed air pipeline by 1.8 metres (6 ft) were required; these steps were to enable installation of the drilling and tapping ("Drill & Tap") area for the "DCM1" Giga Press-based casting line at the Fremont factory.[f 1] Preparations for the Drill and Tap (D&T) area required in-filling of a pit.[f 7] [f 8] Several platforms required installing.[f 9][f 10]

At the end of July 2020, Tesla filed permit applications for construction work in preparation for Die-Casting Machine #2 (DCM2) at Fremont.[f 11][f 12]

By early-August 2020, the casting cell and first Giga Press were substantially complete, having been assembled in the open air at the north end of the General Assembly building.[22] Permits for the testing laboratory were filed during August 2020.[f 13] (37°29′51″N 121°56′46″W / 37.4975°N 121.946°W / 37.4975; -121.946 (Tesla Die Casting Machine (DCM1 + DCM2): Giga Press OL6100 CS))

During September 2020 the first Giga Press at Fremont (DCM1) started producing trial runs of the Model Y single-piece rear casting,[23] and the second Giga Press at Fremont (DCM2) had been installed.[23]

Germany

As of July 2020 plans for the Tesla Giga Berlin factory in Brandenburg included provision and piling foundations for eight 6,100-tonne-force (60,000 kN) die casting machines.[20][24] (52°23′49″N 13°47′35″E / 52.397°N 13.793°E / 52.397; 13.793 (Tesla Die Casting Machine building: 8 foundations for Giga Press / 6100-tonne))

Tesla Model Y vehicles built at Giga Berlin will have a redesigned structure.[25] European Model Y cars will use a front chassis megacasting, in addition to the rear chassis megacasting.[26] The first 1‒2 Giga Press machines at Berlin will be required for the Model Y chassis production, with the remainder allowing flexibility in casting large numbers of parts quickly.[26] The first two European Giga Press machines were planned to be delivered to Giga Berlin by the start of 2021.[18]

Shanghai

Idra's parent company, LK Machinery[27] held a factory tour in Shenzhen on 27 November 2019, during which a partially-complete machine was visible.[28] During the factory tour, the locally-produced Chinese machine was branded as "Impress-Plus DCC6000".[28]

By October 2020, three Impress-Plus DCC6000 machines were being assembled for Model Y production at the Giga Shanghai factory.[29] (30°52′19″N 121°46′19″E / 30.872°N 121.772°E / 30.872; 121.772 (Tesla Die Casting Machine: 3 Impress-Plus DCC6000))

Texas

Construction workers preparing three Giga Press foundations at the Giga Texas factory site in January 2021

During the night of 18/19 January 2021, concrete foundations for three Giga Press machines were poured at the Giga Texas factory location near Austin, Texas.[30][31] (30°13′12″N 97°37′01″W / 30.22°N 97.617°W / 30.22; -97.617 (Tesla Die Casting Machine: 3 foundations for Giga Press))

On 21 January 2021 the first Giga Press components started to arrive on site.[32][33]

On 22 January 2021 the base frame of the first Giga Press was unboxed and moved into position.[34] By the end of January 2021 one compression platten had been lifted into place, with the other two ready for craning.[35]
