7.0 Conclusion The development stages leading to a novel process named HFQ®, for the manufacture of complex shaped, high strength panel parts, is described in this paper. The main features of the process and the R&D work undertaken to bring the process to a state where it is ready for series production, are explained. Demonstrator parts have been presented and the benefits of the process to enhanced product quality, cost and productivity are highlighted. 8.0 References H. Kabasian and on of Materials A. E.
