In a sleepy village next to Lake Taihu, Geely is embarking on a technical tour-de-force with its 5G Connected Factory. It is here where the all-new fourth generation Emgrand sedan is being made.
Officially, production capacity is 30 vehicles every hour—that’s one car every two minutes. These type of production numbers are essential for keeping up with the massive demand of a car like the Emgrand.
A total of 14 molds currently shapes the exterior body of the 2022 Emgrand. The mounds themselves are provided by the same suppliers who supply the likes of Rolls Royce and Porsche. This level of engineering means that during the stamping process the molds have an error threshold of less than half a millimeter—thinner than a strand of human hair.
As is typical of the Geely Group, the welding shop in Changxing is 100 percent automated and can weld to a super thin 3.5 millimeters. This however, is just the start of the automation present at this factory—here, you can’t go ten meters without seeing one of the many Automated Guided Vehicles or AGVs constantly moving around the factory.
As these vehicles move around (playing the soothing tunes of Kenny G to make you aware of their presence), they all have very specific tasks to complete. This could be the replenishment of front section side panels in the soldering shop, or moving a delivery cart full of parts to someone on the final production line. But how does each robot know what it is supposed to do? This is where the 5G of the factory’s namesake comes in.
A factory-wide, super-fast 5G+ network covers the factory in a net of connectivity that allows for seamless communication between devices and cloud services. Online data entries are updated with live information such as inventory levels, production status, and AGV locations. With this information on hand, these robots will never make a mistake in their deliveries. On a given day, each of these robots will deliver up to 7,000 parts to various areas in the factory.
With a production capacity so high, it’s important for the quality control to keep up. After each car leaves the production line, they are put through a 2.4-kilometer “assault course” with a total of 80 separate tests that check performance, handling, mechanics, and electronics. Only those that pass are permitted to leave.
A three-pronged rain seal test sees how the cars stand up against different levels of water: first, a 360-degree rain test; then, a 3-minute rainstorm and finally, a 3-hour typhoon simulator to make sure not a single drop gets in.
The factory is already at full production that Geely is contemplating adding a second line to produce even more models in the near future. Meanwhile, locally, the Emgrand will be launched by Geely Philippines line-up in 2022, joining the Coolray, Azkarra, and Okavango.
