Hot Form Quench (HFQ®)

The lightweighting technology standard for cost- effective, complex geometries for high-strength aluminium pressings by reducing weight for simpler, stronger structures.

The HFQ®  technology press forms hot aluminium blanks at high speed, which are quenched in the press tool, followed by artificial ageing to achieve full strength.

HFQ® technology enables extremely complex aluminium parts to be formed in a single press operation, whilst achieving high levels of strength in the finished part using standard grades of aluminium.





HFQ® technology

Typically 5-10s cycle time from sheet entering press to form & quench

Increased Design Freedom

HFQ®  Technology provides engineering teams with enhanced design freedom, including the ability to achieve tight radii for the design of slender A Pillars with improved occupant vision.

HFQ also enables high levels of part integration with reduced part count whilst achieving high levels of strength.

Reduced Springback

Negligible panel springback required for the part or press tool design leads to reduced try-out and development time and repeatable panel dimensional tolerances.

Increased Lightweighting

 -20% weight reduction compared to some conventionally pressed aluminium grades for strength dominated applications.  

HFQ® Technology is being used to reduce vehicle weight. Additional weight reduction is achieved through part integration and the deletion of joining flanges.

Reduced Piece and Investment Cost

HFQ® Technology enables part cost reduction through down gauging of panels, and by combining multiple conventionally formed and assembled panels into a single HFQ pressing.

Examples of part integration include A/B Pillars, Lamp Cans and Drain Channels. HFQ Technology enables investment reduction by the deletion of multiple forming tools and reduced part count, which also drives assembly savings.

Featured Applications

Lightweighting automobiles and vehicles is one of the best ways for reducing carbon emissions. When it comes to Steel vs Aluminium – Hot Form Quench Aluminium Forming is winning the race.


Hot Form Quench is also ideal for aerospace lightweighting providing super-strength lightweight aluminium and flexibility of use. An ideal lightweighting solution for aircraft and the aerospace industry.
