Future CAR body processing solutions

The automotive industry is undergoing tremendous changes, especially with new materials and production techniques. As a result, servo stamping for work and new material blending techniques for steel, aluminum, magnesium and plastic have become a real challenge.

Automotive industry experts, supply industry experts, and material development representatives, such as press and molding machine manufacturers, occasionally meet to exchange information on the future development of the industry, the German Society of Engineers (VDI) large molding tools professional council will hold such a forum. In a recent forum, various experts discussed new production plans for future body-working, and more accurately said that there will be new materials and new production plans, which poses a daunting task for automakers. The automotive industry needs to work hard to meet environmental, urban, political, economic, cultural and customer requirements. “Basically every process” will be replaced. Dr. oseichtact, an engineer at BMW's shares in Munich, said. New materials require new production plans,

Now, the improvement made by car manufacturers is about the bodywork: "At BMW" we have identified two new solutions. Meinhardt said, “One of the solutions is the traditional conventional body-loaded shell structure, which consists of high steel and solid steel and aluminum; the second option is called a live drive solution, made of strong fiber plastic (CFK or Composite material)."

The body design of the outer casing is mainly composed of a mixture of metal materials, in which more aluminum and aluminum alloy are used, because the first time they design the idea of using lightweight structure, the door parts and the B column use aluminum, but also the steel aluminum alloy. Customized products for specific areas, such as the front panel, magnesium alloys are also beginning to work. All of this, of course, has an impact on the production and manufacturability of the part, first of all, to ensure the reliable formation of new materials, especially solid steel. Next, the press shop has changed and new molding processes such as thermoforming or casting of aluminum and magnesium have to be mastered. The new stamping equipment developed by Schuler with servo technology offers more possibilities than existing molding equipment, and the tools are often replaced because of the small batch requirements.

Ingo von Wurmb is an experienced stamping shop worker who has been directly involved in the change. He often studies these and will implement it in the future body and try to standardize the technology. “We are constantly optimizing the value chain, first by planning to determine batch and inventory levels, and then by inventory occupancy, shortening the production time from the coil to finished coffin parts,” explains Wurmb.

The choice of stamping technology depends on the part

In the Wurmb report, the coefficients are also represented by charts, comparing different types of stamping, such as tool change time, mission duration, hourly throughput, and productivity (Figures 2, 3). It can be clearly seen that servo stamping has a significant trend in productivity, but the choice of which stamping technique ultimately depends on the part. The topic of stamping technology and composite and hybrid mounting methods for tool manufacturing is still under discussion. There are many factors to consider for the re-layout of automotive manufacturing. Therefore, the topic of the VDI seminar “New Solutions for Future Body Processing” will continue.
