Hot Form Quench (HFQ®) - an aluminium hot forming lightweighting technology - is an industrial stamping process for the production of deep drawn, precise and complex geometry ultra-high strength aluminium sheet components.[1][2][3] It is the aluminium hot stamping (sometimes also called 'aluminium hot forming') process for age-hardening grades of sheet and has similarities to the press hardening of ultra-high strength steels. HFQ, the original aluminium hot stamping process, exploits viscoplasticity of aluminium at high temperatures to facilitate the production of lightweight structures, often replacing steel, composites, castings, extrusions or multiple cold formed pressings.[4][5]
Hot Form Quench (HFQ) is an aluminum hot stamping process for high strength sheet (typically) 2xxx, 6xxx and 7xxx series alloys,[6] that was initially developed in the early 2000s by Professors Jianguo Lin and Trevor Dean at the University of Birmingham and then at Imperial College London, both in the UK.
Impression Technologies Limited (ITL), a materials technology company based in Coventry, UK, has exclusive commercialisation rights for HFQ aluminium hot forming, and has since developed its own additional know-how and rights in this domain. At the same time as the first HFQ applications were adopted in automotive applications (the Aston Martin DB11[7]) in 2016, other organisations in the lightweighting ecosystem joined Impression Technologies on a Horizon 2020 programme called LoCoMaTech [8] with an aim to take the HFQ Technology towards mass volume applications. ITL, having installed the world's first HFQ line at the old Jaguar site at Lyons Park Coventry,[9] has started licensing the HFQ Technology around the world to manufacturers, such as fischer group in Germany, EMI Aerospace in US, and Jet Wagon in China,[10][11][12] supplying the automotive and aerospace sectors.
