这种热成型工艺适合于大批量制造产品，与创新的温度 控制技术相结合，实现了对成型过程的精确调节。到目前为 止，电子组合元件的生产包括构建和功能组件制造一直到组 装和布线。就时间和金钱而言，这些都是昂贵的步骤。现 在，IVV通过一个合作项目，已开发出一种新的成型技术，该 技术首先使用已有的用于印刷和组装的技术，在平面状态下 加工基板。仅在最后一个加工步骤中，才需要通过成型技术 制成3D几何形状。例如，交互式（操作）面板可以通过优化 的成本生产。 机器人技术、家用产品、医疗技术以及汽车和飞机制造 行业中的应用将从这种新技术中获益。因为这种技术能够最 好地满足这些行业对人体工程学、设计和功能的高要求。新 工艺还提供了更大的设计自由度和灵活性。 按客户需求定制成型工艺 弗劳恩霍夫 IVV正在开发创新的加热和成型技术，以制 作新颖的产品。位于德累斯顿的弗劳恩霍夫 IVV拥有一支专 业的团队，为3D电子元件的开发提供支持，并在产品设计、 材料选择和工艺配置等方面为各家公司提供帮助。 自行开发 的特性化方法可以确定加工工艺极限和相应的工业负载极 限。 此外，热成型试验台可在经过测试的基础上灵活地生产 产品。 对于这项工作，可以使用各种成型工艺和技术。 使用 实验和数值模拟，可以模拟和优化制造工艺和产品几何形 状。 热成型试验台使德累斯顿弗劳恩霍夫 IVV 能够采用多种 材料为各家公司的印刷电子元件生产产品。 T hermoforming is suitable for large batches of products and is combined here with innovative technologies for tempera- ture control in order to precisely regulate the forming process. Up until now the manufacture of electronic assemblies from structural and functional components has involved production, assembly, and wiring. These are costly steps in terms of time and money. A collaborative project has now developed forming technology whereby a substrate is first processed in its planar state using established technologies for printing and assembly. Only in the last processing step is the 3D geometry generated by forming. Interactive (operating) panels can, for example, be produced at favorable cost. Applications in robotics, home products, medical technology, and the car and aircraft manu- facturing industries will benefit from this. The high require- ments on ergonomics, design, and functionality in these indus- tries will hence be optimally met. The new process also offers greater design freedom and flexibility. Customization of forming processes The Fraunhofer IVV is developing innovative heating and form- ing technologies to realize novel products. The Fraunhofer IVV Dresden has a specialist team supporting the development of 3D electronic components and offers assistance to companies with aspects such as product design, material selection, and process configuration. A self-developed characterization meth- od enables process limits and relative industrial load limits to be determined. In addition, a thermoforming test rig enables the flexible manufacturing of products on a trial basis. For this work a range of forming processes and technologies are available. Using experimental and numerical simulation, manufacturing processes and product geometries can be simulated and opti- mized. The thermofoming test rig allows the Fraunhofer IVV Dresden to form a variety of materials with printed electronics for companies. 54 3D电子元件热成型–来自研究所 Extrusion Asia Edition 1/2020 Fraunhofer Institute for Process Engineering and Packaging IVV Heidelberger Str. 20, 01189 Dresden, Germany www.ivv.fraunhofer.de/en/dresden.html 薄膜挤出 : 全球首条7+米生产线： BOPA薄膜业的又一个里程碑 Film Extrusion: World’s First 7+ m Line – Another Milestone for the Production of Biaxially Oriented PA Films 当中国BOPA薄膜的领先者、全球最大的薄膜生产 商厦门长塑投资时，整个塑料行业都在关注 - 再次得到 充分证实。 刚刚从布鲁克纳机械有限公司订购了2条新 的分次拉伸薄膜生产线，这是迄今为止同类产品中最 快，最宽和最强大的：工作宽度为7+ 米，生产速度340 米/分钟，每小时产量超过2.5 吨。 When the Chinese BOPA film pioneer and world’s largest producer Xiamen Changsu makes an invest- ment, the industry listens up – fully justified again. They just now ordered two new sequential film stretching lines from Brückner Maschinenbau which are the fastest, widest and most powerful of
