Discover Expromet’s specialist rail component expertise at RSN Derby
Expromet Technologies Group is looking forward to exhibiting at RSN 2025 in Derby, the UK’s premier rolling stock networking event, where we will showcase our advanced machining, casting and EN 15085-certified welding capabilities for the rail industry.
Operating from Metaltech Precision, our precision engineering facility in Somerset, Expromet supports major OEMs and Tier 1 suppliers with the manufacture of critical rail components, combining CNC machining expertise, specialist materials knowledge and full lifecycle production capability.
EN 15085 welding: assuring rail industry compliance
A standout feature of our offer is our EN 15085 certification—a European welding standard specific to railway vehicles and components. This accreditation is held by relatively few UK machining companies and demonstrates our ability to meet the stringent safety, traceability and quality demands of the rail sector.
From assemblies in braking and signalling, to underframe and power systems, our welded and machined components are designed for long-term, safety-critical performance.
Expert machining of REMKO Soft Iron and SG Iron components
At RSN, we’ll be highlighting our role in producing key components for applications ranging from shoe-gear and pantograph; to main body, signalling and more. Expromet Group has technical experience working with a wide range of materials including steels, titanium, ferrous and exotic alloys.
Our ability to machine challenging materials like REMKO soft iron – used for its low coercivity and high magnetic performance – is a testament to our specialist skillset and process control.
Full casting-to-machining capability with Expromet Technologies Group
As part of Expromet Technologies Group, Metaltech Precision can provide seamless access to high-integrity castings produced by sister companies Haworth Castings (sand casting and gravity die casting) and Investacast (investment casting and pressure die casting).
This group-wide capability allows us to deliver fully machined and finished rail components, from cast part through to final inspection, simplifying the supply chain and reducing lead times for our customers.
Non-China supply routes and global sourcing flexibility
In response to growing demand for diversified global sourcing, the Group offers varied supply routes to mitigate risk and navigate geographical barriers, particularly for customers in the US and Europe.
Whether you’re seeking to reduce exposure to shifting international trade policies or ensure continuity of supply in an uncertain geopolitical climate, we provide alternative sourcing strategies that maintain quality, cost control and lead-time reliability.
CNC machining capability in the UK and the Philippines
To support increasing customer demand and provide greater manufacturing flexibility, Expromet has recently expanded its operations into Asia with a new CNC machining facility in the Philippines.
This gives customers access to a dual-site production model, combining UK-based engineering expertise with cost-effective machining capacity overseas. For rail customers, this means:
- Enhanced supply chain resilience
- Scalable volume production
- Consistent quality aligned with UK standards
- Competitive lead times and pricing
