A new hybrid manufacturing method could boost capability in the UK and increase manufacturing efficiency for key aerospace components, which could in future be used by global manufacturers to produce aircraft.
Shropshire-based SME, SDE Technology, a lightweight engineering business, is leading an initiative to develop a new superplastic forming process, enabling the company to expand into the aerospace market.
The project forms part of the National Aerospace Technology Exploitation Programme (NATEP) and is supported by the Advanced Forming Research Centre (AFRC) within the National Manufacturing Institute Scotland (NMIS) Group – operated by the University of Strathclyde and part of the High Value Manufacturing Catapult (HVMC). Boeing and Timet UK are industry collaborators, supporting the project with technical and business activities.
Superplastic forming is a near net shape manufacturing method for producing thin-sheet metallic components and is typically used to create complex-shaped titanium parts used by the aerospace sector.
The new hybrid technique is estimated to shorten the forming cycle time by over 50% and cut the manufacturing cost by as much as 25%, when compared with traditional superplastic forming. Applying this process will enable SDE Technology to enter the aerospace market, strengthening the UK supply chain in high-value manufacturing of titanium parts.
Manufacturing with this new approach uses innovative new tooling which enables a much-reduced process time.
Evgenia Yakushina, forming team lead at the Advanced Forming Research Centre, said: “This work has the potential to unlock opportunities for manufacturers to offer improved, quicker methods of producing key parts for aircraft. So far, the research has demonstrated huge potential with important parallels between the new hybrid method and the traditional approach already evident.”
At the end of the 18-month research project, funded by the Aerospace Technology Institute (ATI) programme through NATEP, the team aims to prove that complex-shaped titanium components can be manufactured to the same specification, tolerances and quality compared to traditional superplastic forming.
Richard Homden, CEO of SDE Technology, said: “This project has huge potential for not only us as a business but also the whole aerospace sector. It is fantastic to be working collaboratively to explore new manufacturing techniques. Hot forming was not previously our area of expertise, but with the technical support and knowledge base from the AFRC we can see it becoming a core element of our business plans moving forward.”
