Toyota Mississippi reveals more about building the Corolla
Toyota Motor Manufacturing Mississippi, or TMMMS, has been assembling Corolla sedans for more than two years now, and now we know a little more about the place. Previously, we were able to see the assembly area only, but today, media members were able to see stamping, body weld and paint areas as well.
Here are some facts and figures:
- TMMMS employs 2,000 people, and another 500 work for on-site suppliers. Another 1,500 employees work for seven other suppliers to the plant.
- The assembly shop is the largest area of the plant at 942,000 square feet. The entire plant covers 2 million square feet.
- Assembly has 608 team members (employees) that install 1,739 parts on a base-model Corolla
- A Corolla rolls off the assembly line every 78 seconds, or some 160,000 per year.
- TMMMS has three on-site suppliers.
- The Final 2 assembly line is where weather-stripping, seats and bumpers are installed. They’re delivered by Diversity Vuteq, the largest onsite supplier
- The final inspection line has 18 process where more than 500 elements are inspected before the cars are given the OK to be sold.
- The plant has two work shifts – Red shift (6:30 a.m. to 3:15 p.m.) and White shift (6:30 p.m. to 3:15 a.m.) – which rotate every two weeks.
- The Body Weld department employs 400 team members who work with more than 350 spot-welding robots. The robots
combine high pressure and high electrical current to create more than 4,000 welding spots on each car.
- The Shell Body Sub-assembly area is where team members and robots work together to assemble doors, hoods, luggage and fenders. It also is where replacement service parts are built. TMMMS is the sole supplier for all 2014 Corolla service parts sold in North America, and soon, in South America.
- The final line in the Body Weld department is where the body is fitted with doors, hood, fenders and luggage and where the body is smoothed in preparation for the paint process
- TMMMS uses a high=tech 3-wet paint process. The Paint Shop has more than 300 team members and 26 robots using the 3-wet process. This process has the primer, base and clear coat applied on a wet-on-wet basis, with only one baking process. To paint the Corolla, 107 processes are used to apply any of nine colors.
- The Stamping Shop and stamped parts store employs 75 team members. This is where the exterior stamped panels are produced. A 4,600-ton press produces one panel ever four seconds.
- The Corolla is built with 75 percent domestic content.
