form possess a varying degree of hardness. Certain batch of frames are too soft and requires additional heat treatment after production of the structural frame however they are susceptible to damage and improper forming during production process. In addition if hardness raw material increases the threshold, crack and improper forming of aluminum material causing high scrap rates. Currently to mitigate this issue, Rimowa production team has resorted into 100% testing of the frame hardness after bending and forming. This is resulting in extended delays in production process and additional costs incurred due to heat treatment and cleaning process that is required to produce a high quality hard frame with well-defined formed features. This situation has created a need to understand the composition of aluminum, investigate into the grain structure and design a new composition / raw material quenching process that would produce a stable extruded raw material with consistent and desirable hardness values. Furthermore once the desired material specification is developed, forming and bending process needs to be simulated in a finite element software to derive a much improved process such that higher hardness aluminum material can be formed without cracks or defects. Once a finite element model is completed, punch and die configuration and forming process parameters are varied and tested in lab settings to validate the finite element model.

形式具有不同程度的硬度。某些批次的边框太软，需要额外加热 然而，结构框架生产后的处理很容易损坏和不当 在生产过程中成型。此外，如果原材料硬度增加门槛，则裂纹和 铝材成型不当，导致废品率高。目前，为了缓解这个问题，Rimowa 生产团队已经对车架弯曲成形后的硬度进行了100%的测试。这是 从而导致生产过程的延长延误和因热处理和 生产具有明确成形特征的高质量硬框所需的清洁工艺。这 这种情况需要了解铝的成分，研究铝的颗粒结构和 设计一种新的成分/原料淬火工艺，以生产稳定的挤压原料 具有一致和理想的硬度值。此外，一旦所需的材料规格 开发、成形和弯曲过程需要在有限元软件中进行模拟，才能推导出很多 改进工艺，使高硬度铝材成型时无裂纹或缺陷。一次 建立了有限元模型，改变了凸模结构和成形工艺参数 并在实验室环境中进行了测试，以验证有限元模型。
