Flexible Solutions for Unique Engineering Requirements

Not every customer fits neatly into a defined industry — and at Boro Foundry, that’s never an issue. With over six decades of experience in general engineering castings, we offer flexible, project-specific solutions backed by technical expertise and production agility.

Whether you have an existing pattern or need something built from scratch, we can adapt to suit your process. Our material range includes all grades of iron, carbon steels, Ni-Hard and Ni-Resist, and select stainless steels, giving us the ability to support a wide spectrum of requirements.

We regularly manufacture castings ranging from half a kilo to 8 tonnes — from complex one-off components to production runs in the thousands. Whether you need a raw casting, a fully machined part, or even a complete assembly, we’ve got the scale and capacity to deliver.

Common components we supply include:

• Bespoke bearing housings

• Gears, brackets and structural supports

• Obsolete or legacy parts for machines

• Heat treatment castings

• Crane wheels and lifting components

• Valve bodies and pump casings

• Iron and steel impellers

• Prototypes and short-run production parts

When a local forging company suffered a breakdown on a bell furnace, they needed urgent replacements for skirt castings and furnace doors. The challenge was finding a heat-resistant alloy that would hold up in continuous operation. We recommended BS 3100 311C11, improved the existing pattern tooling, and delivered on time — helping the client avoid costly delays.

An established crane manufacturer required small-batch castings in EN-GJS-700-2 ductile iron, with full mechanical certification and batch control. We developed a pattern tool that allowed two wheel variants to be cast from a single setup — reducing tooling costs and streamlining production. With ISO 9001 accreditation and large-scale capacity, Boro Foundry was able to meet every requirement with confidence.

A bearing manufacturer approached us with a specialist order for a bearing housing destined for North America. The base alone weighed 2.4 tonnes, with the cap close to 1.5 tonnes — cast in EN-GJS-450-10 ductile iron. Boro Foundry is one of just three UK foundries capable of producing this component in that material — and the only one able to cast and machine both parts in-house. We completed the job, start to finish, in just 12 working weeks.
