The one that was sent to try us!
One of our biggest customers approached us with a difficult task in casting a pump casing with a large degree of internal vane wraparound.
South Lincs Foundry Pattern shop had the task of producing the pattern and it was decided to go for a 3D printed sand core, in order to tackle the internal vane. This helped speed up the process of moulding and helped us overcome a difficult issue of moulding the internal vane.
We managed to cast two successful pump casings and the customer was extremely satisfied with the final result.
