Stamping specialist pivots into space industry

In an exciting development for the UK’s space sector, Brandauer is making significant strides in creating cutting-edge components for space motors. This initiative is part of the £1m ‘Pivot into Space’ programme, funded by the UK Space Agency and led by the Midlands Aerospace Alliance.

Brandauer recognised the potential to apply its capabilities to the space industry’s unique challenges. This project under the Pivot into Space programme focuses on enhancing the company’s ability to stamp ultra-thin electrical steels, a crucial factor in improving motor efficiency and reducing weight and mass – both key considerations for space applications.

One of the most innovative aspects of Brandauer’s work is eliminating the need for secondary stamping lubrication. This development is particularly significant as it reduces the risks associated with vacuum outgassing in the space environment. By removing trace materials from the manufacturing process, the company is addressing a key concern for components destined for use in space.

In parallel with these advancements, Brandauer is developing cutting-edge bonding technologies. The company’s work on infrared and in-die glue bonding aims to improve tensile shear strength, temperature management and thermal resistance of components. These improvements are crucial for the harsh conditions encountered in space operations.

Brandauer’s project exemplifies the goals of the Pivot into Space programme, which aims to help SMEs leverage their existing capabilities to enter the high-growth space industry. The programme provides not only financial support but also valuable technical and commercial guidance, helping companies like Brandauer to overcome the significant barriers typically faced when entering this demanding sector.

Shorter cycle times and more efficiency

Raufoss Technology in Raufoss, Norway, manufactures link arms and other aluminum parts for the automotive industry. By having long-standing partner AP&T upgrade one of the company’s existing forging lines with a new, specially designed 2500 ton hydraulic press, not only have cycle times been reduced but the company can also manufacture larger parts than before. 

Some projects are simply more challenging than others, and in this case the challenge was twofold. The first challenge was the design and construction of the press. To be integrated into the existing line, the new press with its higher tonnage, had to be adapted to the physical limitations of the factory premises. Among these were the ceiling height and the size of the foundation, which required many special solutions.

Secondly, there was the matter of time. Raufoss Technology wanted the upgrade completed as quickly as possible. AP&T’s answer was a tight schedule in which everything needed to go according to plan to reach the finish line.

“We had a tight slot for installation, but AP&T did a good job, and everything was finished on time,” says Ole Ronny Heksum, project manager at Raufoss Technology.

One year after the order was signed, almost to the day, the machines and control system were finally in place.

Explains Mikael Karlsson, product manager of presses at AP&T: “We had to lift the press through the roof of the factory using a crane. Everything went smoothly and the entire installation, including the integration and commissioning, was completed in just 12 days.”

Adds Heksum: “After a period of adjustment, we can now manufacture parts with significantly higher pressing forces than previously, and at a higher production rate.”

Hot and cold forming solutions on show

Group Rhodes showcased its latest innovations for the hot and cold forming of metals and composites within the aerospace industry at the Advanced Engineering exhibition in Birmingham last month. As well as celebrating its 200th anniversary, the company unveiled its latest advancements in superplastic forming and diffusion bonding, while also highlighting its turnkey solutions for specialist machinery in the aerospace sector.

Mark Ridgway, CEO of Group Rhodes, states: “The year’s Advanced Engineering exhibition held particular significance as 2024 marks our company’s 200th anniversary. Our exhibition stand not only honoured key milestones from our remarkable history, but also showcased our latest innovations in metals and composites forming.”

Group Rhodes manufactures and markets machinery from its facilities in Wakefield, West Yorkshire, which it sells to both the UK and global markets. The company has extensive capabilities that include the design, development and manufacture of bespoke equipment and complete turnkey solutions.

The main trading divisions of the Group consist of Rhodes Interform, Craven Fawcett, Hallamshire Engineering Services and BJD Crushers, which manufacture machinery and spare parts for the aggregates, heavy clay and material handling sectors. Rhodes Interform designs and manufactures machinery for the advanced metal and composite forming industries, with a particular focus on the aerospace sector.

On the stand, the company highlighted the evolution of its business since its inception in 1824, and the nurturing of a dedicated workforce in a traditional yet dynamic manufacturing environment.

Advances in die clamping and changing

Roemheld presented various innovations designed to optimise set-up times on presses and punches at the Euroblech 2024 exhibition in Hanover last month. Notably, a new hollow piston cylinder that flexibly adapts to dies with clamping edges of different heights, made its trade fair debut.

The new hollow piston cylinder makes forming work easier, especially for contract manufacturers who use different, non-standard die-clamping edges. According to the manufacturer, the element is suitable for clamping edges with a difference in level of up to 30 mm. Users can set the desired height in increments of 1 mm. The new hollow piston cylinder offers clamping forces of 60 or 100 kN and is suitable for use with an operating pressure of up to 400 bar.

Among other new innovations at the show were Roemheld’s pull-push chain systems for loading presses and punches, which is intended for almost all application scenarios and dies up to 40 tonnes. It is suitable for installation either directly on the system or on a rail-bound transport system. Alternatively, for loading by crane, it is possible to integrate the system into a manually or electrically driven die-changing console.

The pull-push chain system is available as a complete solution in various standard versions and with different control variants. Since all components are designed to work together, the manufacturer promises a quick and simple “plug and play” installation.

A redesigned arch clamp for dies with straight clamping edges was also on display for the first time. The clamp suitable for dirty, hot environments up to 250°C on press beds and rams in sheet metal forming, die casting and forging applications.

Alan Spargo invests in Bruderer press

A specialist supplier to the Formula 1, automotive and aerospace sectors is increasing its tool try-out capacity by purchasing the company’s first Bruderer press. Alan Spargo Ltd, which will celebrate 50 years in business in 2025, has invested in a BSTA 40-tonne machine to help provide its growing list of customers with the option to test tooling solutions at high speed before they go into production.

The technology can offer up to 1000 strokes per minute at precision accuracy and will support the High Wycombe firm’s desire to increase sales past the £3m mark before the end of 2024. The investment also builds on a long-term tooling relationship between the company and Bruderer UK, which culminated in the development of a turnkey production line for Bruderer’s stand at the MACH 2024 exhibition in Birmingham earlier this year. Alan Spargo developed specialist tooling in just six weeks to run on a Bruderer BSTL 350-88 high-speed press.

Peter Spargo, director, says: “Our customers are continually pushing the boundaries when it comes to tool performance, and we must respond. One of the ways we can do this is by giving them access to even more tool try-out capabilities and that’s why we’ve pressed the button on our first investment in Bruderer technology. This complements our other presses and, importantly, gives us a press that can deliver high-speed performance, testing the tool to its maximum. We’ve already got several existing and new customers who can take advantage.”

He continues: “The past 12 months have been very good for us. We’ve extended the workforce to 22, with the opportunity to recruit more staff, including new apprentices.”
