This is How a Gearbox is Made

Release Date: 03 March 2017
  • SEAT Componentes manufactures 18 million parts every year to assemble more than 660,000 gearboxes 
  • 15,000 tonnes of aluminium are smelted every year, enough to make 220 commercial airliners 
  • Gears are changed over 500,000 times during the service life of a gearbox

Martorell, 03/03/2017.- The SEAT Componentes plant in El Prat de Llobregat, Barcelona, has been allocated the Volkswagen Group’s new MQ281 gearbox, a part that will be made there for the entire world. For the first time, a carmaker has installed POV cameras at different stages of the manufacturing process to show everything involved in making them in an accelerated video lasting 60 seconds.

- A gearbox every 27 seconds: Every 27 seconds, a new unit leaves the SEAT Componentes plant, which ranks first in manufacturing time for the Volkswagen Group’s five-speed manual gearboxes; more specifically, one hour and 41 minutes in total.

- More than 13.5 million gearboxes: SEAT Componentes has manufactured over 13.5 million of the MQ200 model gearboxes. These units are used in 29 Volkswagen Group car models and are exported worldwide. In 2016 a total of 661,277 units were manufactured, a figure that is expected to slightly increase this year.

- Smelting at 700°C: Manufacturing the gearboxes requires smelting 15,000 tonnes of aluminium every year, the amount used to make 220 commercial airliners. The ingots are loaded into kilns at nearly 700°C for smelting. Several injection moulding machines solidify the molten aluminium into a rough part in 20 seconds.

- 18 million parts every year: Each gearbox is made of 174 parts. Annual in-house production at SEAT Componentes totals more than 18 million parts, including shafts, gearwheels and timing mechanisms.
- 250,000 kilometre lifespan: The parts that are manufactured in-house undergo heat treatment to ensure their durability, and can remain up to 14 hours at a temperature of 900°C. This process enables the service life of a gearbox to be multiplied by 5,000, which is estimated to be an average of 250,000 kilometres. During its service life, 500,000 gear changes on average are performed.
-A process that recycles: At the SEAT Componentes plant, 95% of the aluminium used gets recycled, as well as the majority of the oils and other consumables used in the manufacturing process.

- Machinery used: More than 500 machines and robots are involved in the manufacturing process of a gearbox.
