Established and trusted

Our work has been relied upon for decades to provide safe and long-lasting solutions to a wide variety of sectors such as Civil, Medical, Marine, Defence, Automotive and even Aerospace.

Inside Big Ben

The clock mechanism was destroyed in 1976 by falling weights. Working with original plans from 1856, we cast and machined new parts and had Big Ben repaired for Queen Elizabeth II’s Silver Jubilee visit to Westminster in May 1977.

Global defence systems

Our work is seen around the world in military and private defence systems such as gun turrets and equipment housings. This work is done to extremely tight tolerances and made compatible with later-stage arms manufacturers.

Automotive and power

We cast a wide range of large aluminium-body diesel engines used in road automotive, land trains, marine vessels and mass power generation applications. Across land and sea, our work is helping to power both private and public transport systems and the cities they visit.

Medical and healthcare

We cast and machine components and equipment for national and international medical markets, including state-of-the-art devices such as magnetic resonance imaging (MRI) scanning systems.
