Today, the William Cook group is the UK’s largest producer of steel castings and can offer a wider range of moulding processes, steel specifications and casting weights – from a fraction of a kilogram to 12 tonnes – than any other manufacturer in Europe. Design and patternmaking William Cook works closely with customers to optimize their casting designs for manufacture. We prefer to manufacture new patterns ourselves, to ensure complete compatibility with our moulding processes.
