This project seeks to increase the output rate of High Speed Blow Forming (HSBF), a process developed by Verbom that allows superplastic forming of aluminium sheets at high speed. This process achieves a production time of a few minutes per part, but the long-term objective is to reach a production rate of 120 parts per hour. To achieve this, novel strategies regarding the heating of the sheets to superplastic temperatures (~500 C) and the sealing of the sheets in the mold cavities must be developed as these have been identified as the main limitations in increasing the process rate. The expected outcomes of this research project are proof-of-concept prototypes of direct resistance heating and compliant sealing technologies for small-scale aluminium sheets (0.3m x 0.3m). A full-scale (2m x 2m) implementation study will also be realised, allowing Verbom to start testing these technologies in their installations. It is expected that at least 2 patents will result from this work, giving a commercial edge in sheet metal processing for Verbom, and widening the market in the automotive industry, thus increasing the need for aluminium transformation for the Canadian aluminium producers. This project will help to democratize the aluminum usage in vehicles. By offering more design freedom and better pricing, we will expand the number of projects where business cases will justify the switch from steel to aluminum. The result will be lighter vehicle, less energy consumption, better range for electrical vehicle, less pollution and smaller carbon footprint. It will also allow AluQuébec to transpose or combine the knowledge acquired in this project with other aluminum transformation processes, which will in return expand the use of Canadian Aluminium to other markets. This project will contribute to the training of the next generation of highly qualified personnel in the aluminum transformation, which strategic to the Canadian industry.

该项目旨在提高高速吹塑成型 (HSBF) 的产量，该工艺由 Verbom 开发，可实现铝板的高速超塑性成型，该工艺可实现每个零件几分钟的生产时间。长期目标是达到每小时 120 个零件的生产率，必须开发有关将板材加热到超塑性温度（~500 C）以及将板材密封在模具型腔中的新策略。这些已被确定为提高处理速度的主要限制。 该研究项目的预期成果是用于小型铝板（0.3m x 0.3m）的直接电阻加热和合规密封技术的概念验证原型，还将实现全面的（2m x 2m）实施研究。 ，使 Verbom 能够开始在其装置中测试这些技术。预计这项工作将产生至少 2 项专利，从而为 Verbom 带来钣金加工方面的商业优势，并扩大其市场。汽车行业，从而增加了加拿大铝生产商进行铝转型的需求。 该项目将有助于实现汽车中铝材使用的民主化，通过提供更多的设计自由度和更好的定价，我们将扩大商业案例证明从钢转向铝的项目数量，从而使车辆更轻，能耗更低。 、更好的电动汽车续航里程、更少的污染和更小的碳足迹，这也将使 AluQuébec 能够将该项目中获得的知识与其他铝加工工艺相结合，从而将加拿大铝业的使用扩大到其他市场。项目将有助于培训铝转型中的下一代高素质人才，这对加拿大工业具有战略意义。
