Turnkey rail supply chain solutions from Expromet group

Expromet Technologies Group provides a one-stop shop for the rail and rolling stock components supply chain. Our expertise in component manufacture for the rail sector includes EN15085 accreditation, with precision CNC machining, stainless steel casting, forging, welding and assembly, all available in-house through our extensive UK manufacturing and fabrication facilities.

Let’s see why Expromet should be your manufacturing partner of choice for rail and rolling stock components.

Trusted experts in safety critical infrastructure

Expromet group companies specialise in the manufacture of safety critical components and assemblies for high-risk, zero-tolerance environments, including the aerospace, defence and transport sectors. We have the expertise to advise on the optimal materials for your rail and rolling stock components, and manufacture precision components to ensure that they will meet or exceed specifications.

Our team of fully-coded welders, fabricators and CNC engineers work to high standards. Metaltech Precision has achieved accreditation for demanding sectors such as AS9100 (aerospace & defence) and ISO 3834  (quality requirements for fusion welding of metallic materials), and newly accredited EN15085 (welding of railway vehicles and components).

Our capabilities for rail and rolling stock manufacture and supply

Expromet group companies have proven experience in fully integrated manufacturing supply solutions to the rail sector. This includes supplying components for British Rail Class 450 and British Rail Class 700 electric passenger trains; for the London Underground; and for other rail applications.

CNC machining, welding and fabrication for rail and rolling stock

Metaltech Precision provides precision CNC machining, fabrication and welding at their 50,000 square feet facility in Somerset. With an extensive plant list, Metaltech Precision has the capability to manufacture a wide range of components, including:

• Gears, shafts, pullies and sprockets
• Worms and worm wheels
• Pinion sets and gear races.

Castings and forging for rail and rolling stock

Investacast offers castings in grey iron, as well as stainless steel castings and forging capabilities, supplying precision components such as studs and manifolds for the rail sector.

Rapid repair and overhaul of rail components

The failure of a key component can have serious consequences for the operator, so we offer overhaul facilities for rail and rolling stock to check on strength and durability.

We also offer a fast repair or replacement service to get your transport facility back up and running if a component should fail or need to be replaced.  Our capabilities include rapid reverse engineering of discontinued or broken parts:

• Large or small components, from micro sliding head CNC machining to large capacity CNC 1,250mm turning and 2,500mm milling
• Simple or complex parts
• Small volume to large orders.
