The legislative targets to develop more fuel-efficient vehicles, and thus to reduce energy consumption and air pollution, are a challenge for the automotive industry. Lightweighting is one of the most effective approaches to achieve these targets. A highly innovative forming technology to form lightweight aluminium panels (solution Heat treatment, Forming and in-die Quenching: HFQ) has been developed and patented by Imperial College London and is being commercialized by ImpressionTechnologies Ltd. Four major benefits are realized by the HFQ technology: high formability, superior post-form strength, short processing time and low springback. Comprehensive studies and analysis on the formability, post-form strength and springback of the HFQ forming process are presented.
