Aluminium and Bronze Castings

Aluminium and copper-based bronze castings

We have been providing a comprehensive and industry-leading casting service from our own ferrous foundry since the 1960s. Patterns, castings and machining – all within one single workflow.

We produce a wide range of precision aluminium castings up to one tonne and copper-based bronze castings up to 120kg each. We are also experts in gravity die aluminium castings at up to 50kg and of truly exceptional integrity. Plus, we have a full range of heat treatment specifications.

We specialise in the casting and machining of large, high complexity, sand castings that operate in demanding conditions such as high temperatures, immersions and completely pressurised systems.

Our facilities and procedures have developed to offer low-volume, multiple-batch and large-scale production quantities of components – all from one single enquiry and within one single location.
