Dudley, UK — July, 2026
From an initial CAD model to a finished product ready for installation, the manufacture of a cast iron penstock involves a number of specialist processes — and, in this case, they all take place within the Midlands supply chain.
The latest circular cast iron penstock from Industrial Penstocks Limited begins life as a digital design before moving through a series of manufacturing stages, including pattern making, casting, machining and final assembly.
The process brings together different areas of specialist engineering expertise to transform the original design into a finished flow control product ready for use on site.
For Industrial Penstocks Limited, keeping this manufacturing journey within the Midlands reflects a continued commitment to UK engineering and the region’s established manufacturing heritage.
The penstock also carries the Simon-Hartley name, which has a long association with flow control manufacturing. The heritage of Simon-Hartley forms part of the wider expertise behind the group’s approach to designing and manufacturing flow control solutions.
From the foundry through to machining and assembly, each stage contributes to the finished product, demonstrating the skills and manufacturing capability that remain an important part of the UK’s engineering sector.
The result is a cast iron penstock manufactured through a local supply chain, combining traditional manufacturing processes with modern design and engineering.
