中空形状，特别是公路车辆动力传动系的轴，是技术创新的主要潜力，因为这些部件必须特别坚固，而部件重量和单位成本受到高度限制。这一创新战略需要关注广泛的产品和技术开发学科，并要求对所需的生产技术进行密集和先进的跨学科开发。中空形状可以用旋转挤出工艺生产。旋转挤出是一种灵活的旋转压力成型工艺，可应用于无法通过可比工艺获得的尺寸范围，而不是以成本效益高的方式或用于非常昂贵的材料。旋转挤出是一种增量技术，这意味着在分析描述过程和目标过程控制方面也存在已知的困难。能量方法已被证明是最实用的，因为它可以区分对过程有影响的各种因素和参数，同时将它们应用于机器和过程控制。工艺开发的结果是通过成形制造中空轴部件的新加工原理，以满足汽车工业和其他具有重要精度和安全要求的行业的特定需求。
Hollow shapes, particularly the shafts of road vehicle power trains, are a major potential for technical innovation since these components have to be especially strong while component weight and unit costs are highly restrictive. This strategy for innovation requires focusing on a wide range of disciplines of product and technology development and demands intensive and advanced interdisciplinary development of the required production technology. Hollow shapes can be produced with the spin extrusion process. Spin extrusion is a flexible rotatory pressure forming process which can be applied in dimensional ranges that cannot be attained by comparable processes, not in a cost‐effective fashion or for very expensive materials. Spin extrusion is an incremental technique, meaning there are also the known difficulties standing in the way of analytically describing processes and targeted process control. The energetic approach has proved to be the most practicable because it makes it possible to differentiate between a wide range of factors and parameters having an impact on the process while applying them to machine and process control. The results of process development was a new processing principle for manufacturing hollow shaft components by forming for specific needs of the automobile industry and other industries with major accuracy and safety requirements.
