On June 28, 2024, Sailes Automobile and Wencan Group held the IDRA 10,000-ton super die-casting machine production robot integration casting processing technology application launch ceremony, announcing the official production and application of the IDRA 10,000-ton super intelligent die-casting unit, and the first application of Shanghai Fanuc’s independently developed high-precision robot processing technology. At the event, leaders from the Chongqing Economic and Information Commission, the Liangjiang New Area District Committee, Sailes Group Chairman Zhang Xinghai, Wencan Group Chairman Tang Jiexiong, and other leaders attended to witness this important moment together.
High-end products come from high-end manufacturing, which requires high-end technology. The commissioning of the IDRA 10,000-ton super die-casting machine sets a new benchmark for intelligent manufacturing in the automotive industry, driving the industry towards a more advanced, intelligent, integrated, aggregated, and efficient future. Zhang Xinghai said, “The upcoming 10,000-ton super intelligent die-casting unit is the world’s first and largest two-plate die-casting unit. This is the result of our pursuit of lightweight and environmentally friendly cars over the years, as well as the result of the integration and aggregation ‘two transformations’ project implemented by Saicli Automotive under the ‘33618’ strategy in Chongqing. It can meet the increasing demand for smart travel experiences by users, making cars safer and users more proud.” The integrated die-casting process for cars, through integrated manufacturing, achieves innovations in traditional car manufacturing processes by achieving lightweight, cost savings, shortening supply chains, and increasing manufacturing scale. Saicli Automotive, as a technology and science enterprise, has always adhered to the path of intelligent electrification development, and is deeply interpreting the concept of “new luxury” by reshaping luxury with intelligence and leading the innovative development of industry technology and intelligent manufacturing based on research and development and intelligent manufacturing capabilities. Wen Can, as a leading domestic die-casting equipment manufacturer, has accumulated a good reputation and unique brand advantages in the field of automotive casting components after more than 20 years of development, and has been the first to obtain customer designation and mass production in the field of large-scale integrated automotive structural components, becoming a leader in integrated die-casting.
The IDRA 10,000-ton super intelligent die-casting unit, produced through advanced die-casting technology and intelligent control system, significantly improves production efficiency, reduces costs, and enhances vehicle structural strength and stability. Sailes Automobile also announced the pioneering application of Shanghai Fanuc’s high-precision robotic large milling technology for integrated processing and upgrading of large castings, achieving high efficiency in processing accuracy, rigidity, and speed. What are the advantages of die-cast body?
More and more car companies are adopting large die-casting body technology. What are the advantages of this new car manufacturing process? For car companies, it can greatly improve production efficiency. Integrated die-casting technology integrates multiple parts into a single large component, reducing assembly processes and significantly increasing production efficiency. Another advantage is reducing production costs. Integrated die-casting technology helps reduce manufacturing costs by reducing processes and labor. Take the Wey VV7 M9 as an example, die-cast body parts increase part integration by 95%, reduce the number of welds/connection points by 70%, and increase body torsional rigidity by more than 23%.
In addition, the higher the clamping force, the higher the yield rate can be ensured. Die casting technology uses pressure to press hot liquid metal into the mold. If the pressure is not high enough, the liquid metal may solidify before reaching the end of the mold. Therefore, the higher the pressure, the faster the liquid metal flows, and the faster it can fill the entire mold before solidifying. This is why it is always emphasized the “clamping force”, also known as tonnage.
From the scene, it can be seen that it takes about 2 minutes from feeding, die casting, outputting die-cast parts, correcting die-cast parts to the initial finished product, and there are only three workers in the entire work station, the production efficiency is very high. If it were the traditional stamping + welding process, a large part would need to “complete” the production line for one hour.
For vehicles, die-cast body can lighten the vehicle. Integrated die-casting technology usually uses aluminum alloy material, which helps reduce the weight of the body, thereby improving the endurance of new energy vehicles. It can also improve safety. Integrated die-cast body reduces a large number of welding points, making the overall structure of the vehicle have higher strength and torsional rigidity, improving the safety of the vehicle. In addition, it can increase space utilization. Since the battery is usually laid flat under the car, integrated die-casting technology can more effectively combine the body with the battery, thereby increasing interior space.
