Defence High Pressure Components Project

In 2020 Bowmill, working in partnership with a major prime defence control systems provider, were awarded a package of multiple parts within a strategic work transfer.



In order to accommodate this award Bowmill invested in a new assembly area along with new, enhanced equipment within the existing pressure testing facility.

This operational expansion brought the assembly capability within Bowmill up to 4 individual build areas, and a pressure testing service which could use Hydraulic oil, skydrol and high-pressure water.

The new contract award would entail a high volume of components being processed. To handle the increased quantities, multi-pallet 5 axis machines were introduced.

These machines were best placed to provide high levels of efficiency in the production process, bring capable of optimising methods of machining complex parts to minimal operations.

Pressure testing up to 10,000psi
100’s of components made each month
8 part variations manufactured


In the first 6 months the new products required in this award, along with the new processes they entailed , were fully productionised.

Supply was undertaken to drum beat deliveries, using Failure Mode & Effects Analysis (FMEA) techniques, including gathering historical information in a collaborative approach with the customer. This ensured lessons learnt were applied and a Right First Time manufacture objective achieved.
