Passat, which was launched in 2000, has always maintained its benchmark position in the domestic mid-to-high-end car market by virtue of its excellent product strength, German craftsmanship and strong brand appeal. So far, the cumulative sales volume has exceeded 2.8 million, of which over 60% are produced From SAIC Volkswagen Nanjing Plant.
As the birthplace of Passat, SAIC Volkswagen Nanjing Branch was established in 2008. It is the fourth vehicle production base of SAIC Volkswagen and the first factory outside Shanghai. As for stamping, body, paint, and final assembly, which are the four major processes of the OEM, what are the highlights of the Nanjing plant? Let’s explore them one by one!
High-efficiency high-speed stamping production line Advanced technology ensures high quality
The automatic stamping line of Nanjing factory is the first high-speed automatic stamping production line of Volkswagen Group and China. It consists of one 2100T and five 1200T presses, 7 cross-bar manipulators, 4 KUKA robots and high-speed destacking system. The line punching rate is as high as 15 times per minute, and the actual production can produce up to 60 parts per minute. At the same time, the advanced automatic mold change system is adopted here, the efficiency is increased by 3-5 times, and the exchange of two sets of molds can be completed in only 10 minutes.
Extensive application of laser welding body shop to show hard core strength
Automation and advanced technology are becoming important factors to consider the level of factory craftsmanship. As the first minute factory of the Volkswagen Group, the Nanjing factory also has strong strength in these areas. Its body shop has nearly a thousand imported KUKA robots, which are widely used in The highly automated process of body spot welding, laser welding and gluing not only brings convenience and efficiency, but also improves the process quality of the product.
The Nanjing factory widely adopts laser welding technology, through the high temperature of 1400 degrees, the roof and the side steel plate are completely fused together instantly, achieving the combination at the molecular level, effectively improving the strength of the body by more than 30%, and reducing the deformation of the body in motion . The laser welding length of Passat reaches 3646mm, and the high-rigidity body structure is cast through advanced technology to enhance the safety of the vehicle.
The secret of 12-year vehicle anti-corrosion with new environmentally friendly paint technology
The paint workshop of the Nanjing factory adopts a new type of environmentally friendly paint technology, a large number of frequency conversion control technology, bus control technology, automatic robot gluing, and painting technology. There are 128 robots in total, which can guarantee the quality of the paint to the greatest extent.
The new environmentally-friendly paint technology has cathodic electrophoresis technology, PVC protection at the bottom of the vehicle, wax injection in the cavity and other processes, which can ensure that the Passat can achieve 12 years of vehicle anti-corrosion. In addition to anti-corrosion, it can also achieve bright colors, environmental protection and energy saving effects.
Modular order production to meet individual needs of the final assembly workshop
The assembly workshop of the Nanjing factory adopts a large number of automatic production and testing equipment with the highest level of technology in the world. The biggest feature is modular production, which represents a high-efficiency, high-precision, and small-error production mode, thereby ensuring the quality of the car to the greatest extent. .
At the same time, in order to meet the diversified and personalized consumption needs of customers, SAIC Volkswagen has implemented an order-based production control system in an all-round way. Before the body enters the first station of the assembly workshop, various optional configurations such as engine, gearbox, and even tires have been defined according to customer needs; during the assembly process, the selected correct parts will be selected according to Need to be at the right assembly station at the right time. Satisfy the individual needs of customers to the greatest extent.
Passat’s 20-year journey in China has continued to innovate through self-breakthroughs. The recently launched 2020 new Passat is the first model of the SAIC Volkswagen brand equipped with a smart car connection system, carrying the mission of SAIC Volkswagen’s smart interconnection strategy. The Nanjing plant will continue to uphold SAIC Volkswagen’s ingenuity in making quality cars, and bring better products to Chinese consumers.
