Brooks Forgings Ltd

Brooks Forgings were asked to produce an undercarriage component for use during re-fits of the surviving World War II Spitfire aeroplanes.

Using an old forging and a machine drawing, we created a model of the part in Solid Works then using 3D printing a resin model of the component was produced.

This enabled our client to fine tune the model to ensure the finished part could be machined to accommodate as many different variations of the Spitfire that took place during its colourful history.

Investigations were made to ensure optimum strength was maintained and the most economical method of production established.

The closed die forging process was employed to manufacture the part and is a tried and tested method of producing similar items worldwide. In this instance, it ensures the overall strength of the part by retention of the grain flow. The process also allows for significant reduction of complex machining after the forging process was complete thus reducing the amount of material used and leading to improved delivery schedules as well.

The product was then MPI crack tested after forging.

It’s great to still see them flying today, and for Brooks to play a small part in their history is particularly satisfying.
