Grainger and Worrall hosts global castings authority

A global authority in castings has given a two-day seminar to engineers at complex metal specialist Grainger and Worrall, as the business continues to expand and improve its offering.

Professor John Campbell visited the Shropshire-based business to reinforce the principles of the recognised Cosworth sand casting process, which he helped to develop back in 1978. Now owned by Grainger and Worrall, the process was developed over a lifetime of work in the foundry industry to develop defect-free castings with dimensional accuracy, and high structural integrity.

During the two-day event, John Campbell presented the theory behind the Cosworth process to 40 members of the engineering department, before spending the second day discussing the key principles behind the idea, reinforcing best practice.

Keith Denholm, engineering and technology at Grainger and Worrall, explained that the Cosworth process is as integral to the business today as it has always been.

“As Grainger and Worrall moves into electrification, body in white, and subframes, we continue to operate to the principles set out by the Cosworth process to continually to optimise and lightweight casting materials. Although the process itself may change depending on each application, the principles it is based upon remain as relevant as they have ever been.

“We were delighted that such a recognised global authority in John Campbell was happy to visit our foundry and engage with our engineering team as we continue to grow, following his initial guidelines for castings success.”
