Metal machining

Metal Machining – Precision Components

Dedicated to the precision manufacturing of high-performance metallic components for use in industry’s most demanding applications, our machine shop specialises in the high-precision machining of geometrically complex components in exotic alloys.

Most of our special machining work is customer-specific and covered by confidentiality agreements. However, our components and assemblies are in use around the world in critical applications across the oil and gas, nuclear, aerospace, power generation, marine and pharmaceutical industries.

In association with the elastomer and plastics engineering divisions of James Walker, we can offer simplification of the production chain through single-source supply or providing sub-assemblies and kits.
