William Cook Cast Products

William Cook Cast Products is a Sheffield-based heavy engineering manufacturer combining cast component production with significant in-house CNC machining. The wider manufacturing operation runs machine shops in Sheffield and Leeds with dozens of CNC centres, including 5-axis equipment for milling, turning and boring large or complex parts. This allows the business to supply fully machined components rather than castings alone. The Sheffield operation serves demanding markets including defence, rail, energy and nuclear, backed by established quality, environmental and occupational-safety systems. The profile is tied to the active UK Cast Products legal entity and its Parkway Avenue manufacturing site.
