金属板材型材用于汽车和商用车、飞机和船舶的生产以及工厂建设和其他一些制造过程。拉弯技术既提供了一种非常灵活的方法来生产这些类型的型材，又提供了一种通过使用简单和自适应工具来降低机器成本的设备。除其他已建立的方法外，例如由于产品系列的扩展和原型要求的集中，型材滚压成型和深冲等更灵活的方法变得越来越重要。通过减轻汽车生产中的车辆重量来减少污染物排放的目标需要持续使用轻质结构。拉深弯曲技术可以制造适用于概念轻量化生产应用的负载适应零件。它能够制造沿纵轴具有可调节横截面的主要轴承状零件。汉诺威莱布尼兹大学金属成形和金属成形机械研究所 (IFUM) 与德累斯顿工业大学固体力学研究所 (IFKM) 合作，正在研究不同尺寸和可调整横截面的 U 形型材的制造，以及具有不同翼缘宽度和可调整纵向翘曲的帽形型材的制造。
Sheet metal profiles are used in production of cars and commercial vehicles, aircrafts and ships as well as in plant construction and several other manufacturing processes. The draw bending technology offers both a very flexible method to produce these types of profiles and an equipment to reduce machine costs by the use of simple and adaptive tools. Among other established methods, e.g. roll forming of sections and deep-drawing, more flexible methods gain importance because of the extensioning in product line-ups and concentrating requirements of prototypes. Ambitions to reduce pollutant emission by reducing vehicle weight in automotive production require the consistent use of lightweight construction. Draw bending technologies allow the fabrication of load-adapted parts for applications in concept lightweight production. It enables the fabrication of predominantly bearing-like parts with adjustable cross sections along the longitudinal axis. The fabrication of u-shaped profiles with various dimensions and adjusted cross sections as well as the fabrication of hat-shaped profiles with various widths of flange and adjusted longitudinal warping is being investigated in several research projects at the Institute of Metal Forming and Metal-Forming Machines (IFUM) of the Leibniz Universität Hannover in cooperation with the Institute of Solid Mechanics (IFKM) of the Technische Universität Dresden.
