The Pivotal Role of Sheet Metal Fabrication in Automotive Lightweighting
The Pivotal Role of Sheet Metal Fabrication in Automotive Lightweighting
Date：2024-01-07 11:10
At the cutting edge of the automotive industry, sheet metal fabrication is pushing the vehicle lightweighting initiative forward. This is because the metals and metal alloys used in automotive bodies can be formed into such a wide variety of shapes, thicknesses, and surface characteristics; and because the processes used to form them can be tightly controlled in time and space. Reducing weight in vehicles made from these high-strength materials requires a careful balance. For this reason, automotive engineers have tended for many years to look to height reductions in excess of 4 or 5 percent, which is roughly the threshold at which the human eye begins to perceive a difference. They also like to use localized bumps in sidewalls and other curves in vehicle surface shapes to give the impression of height.
The automotive industry has many benefits from using lightweight sheet metal. First and foremost is the reduction of the vehicle's weight. Wight reduction of the vehicle leads to better fuel efficiency and a reduction in greenhouse gas emissions—this is an essential step toward sustainability. The lightweight materials used can also help chassis rigidity. Because the material can be formed easily, more intricate designs can be made. And with the use of advanced fabrication techniques, a vehicle can almost be sculpted to allow for more visually stunning designs.
The sheet metal fabrication scene is in constant flux, with fresh technology emerging to satisfy the contemporary auto industry's demands. Additive manufacturing, known colloquially as 3D printing, is upending the construction of sheet metal parts—prompting an unprecedented revolution in the materials, processes, and systems of the sheet metal fabrication world. Metal 3D printing is allowing for even greater geometrical liberty than has been enjoyed with lasers and other sheet metal fabrication equipment, and the new production methods are both faster and more efficient. Meanwhile, the tools of our trade—CAD and CAM—have become ever more useful, enabling the sorts of computational algebra that can result in parts that fit together and work together with an efficiency that was never available before. Although the ultimate CAD product is still a drawing on a computer screen (or a projection thereof), the ef...
Sheet metal fabrication in the automotive industry looks to be a burgeoning field, with plenty of sunlight shining on it from several different angles. One is the work being done to develop new alloys with even higher strength-to-weight ratios, a big push towards entirely new materials and structures that would far exceed today's limits. Another is the refinement of techniques of actual fabrication to further reduce everything from "waste" (e.g., scrap) to energy consumed (or, in the case of lasers and other direct means of applying heat, wasted heat). Yet another is the growing trend towards integrating with all kinds of technologies beyond the materials from which the body of the vehicle is made, and these technologies, too, promise real change in the automotive light-weighting field.
Sheet metal fabrication is not simply a manufacturing method; it is a nearly unstoppable engine in the automotive industry’s quest for efficiency, performance, and sustainability. The reason is not hard to see. It uses advanced materials and innovative techniques to fill a crucial niche in the development of vehicles that are lighter, stronger, and smarter. And as the automotive industry evolves, sheet metal fabrication will certainly remain at the heart of automotive design and in the push toward setting new standards for excellence.
