Reliable Logistics Across a Global Manufacturing Footprint
We operate strategically located facilities in Poland and India to bring your supply chain closer to key markets. By splitting production across two continents, we adapt output to your schedule. This approach reduces lead times and ensures stable supply, even as renewable markets evolve and demand shifts.
Inside each plant, we use advanced manufacturing processes to ensure consistent results. Our CNC machining, forging, and stamping methods deliver tight tolerances, preserve conductive properties, and maintain ISO-certified quality standards. Rigorous checks at every stage ensure each part meets your exact specifications, including the option for UL94 V0-rated insulation where safety and compliance matter most.
We tailor turnkey manufacturing solutions to your unique requirements. This includes in-house plating, coating, and finishing, allowing for strategic partial plating and customized surface treatments. Since we control all parts of the process, we can refine products for better performance and cost efficiency. Over time, we adapt methods to evolve with your growing needs, whether you serve established grids or emerging renewable energy projects.

Over 50 Years’ Experience Supporting the Energy Transition
With more than 50 years in operation, MSS International draws on deep metallurgical knowledge and manufacturing know-how. We have worked with copper, aluminium, and specialised alloys across a wide range of applications—from high-voltage transmission systems to energy storage technologies in sustainable power generation. Over time, we’ve developed methods to ensure each component meets demanding criteria for conductivity, durability, and dimensional accuracy, all while adhering to strict industry standards. Throughout decades of growth, MSS International has cultivated strong relationships with customers in over 30 countries. We know how to align production schedules, adapt to changing regulations, and deliver on time. As your partner, we support both legacy power systems and emerging renewable infrastructures, ensuring you’re ready to meet new challenges as your products evolve.
Speak to an ExpertA Dedicated Design Support Team for Your Project Development
Our design team translates concepts into manufacturable solutions. Using advanced simulation software and finite element analysis, we model metal flow, determine optimal material grades, and fine-tune plating thickness before production begins. This early refinement ensures each component meets your specifications—both in performance and cost.
- Metallurgists who optimize metal flow and forging die designs for precise conductivity and mechanical strength
- CNC specialists who refine tool paths for precision, repeatability, and reduced material waste
- Cost analysts who identify partial plating strategies and simpler assembly methods to align with tight budgets and compliance standards
- Project managers who maintain clear communication, schedule alignment, and streamlined logistics for OEM manufacturers and utilities
Once the design is set, our manufacturing teams implement the plan using our in-house capabilities. Every step—from initial sketches to final delivery—is managed under one roof, ensuring seamless transitions, reduced lead times, and consistent results that meet industry demands.
Complete Assemblies & Sub-Assemblies to Streamline Your Supply Chain
Our approach to assemblies and sub-assemblies offers more than just convenience. By consolidating your suppliers into a single, fully managed source, we help reduce procurement complexity and free up working capital. With MSS International, you gain efficiency, quality control, and end-to-end accountability in one place. When we deliver completed assemblies, you bypass the overhead of juggling multiple vendors. Instead, you receive ready-to-install solutions that minimise inventory, contain costs, and streamline production flow. This approach helps you adapt to shifting demand, whether you’re supplying legacy grids, building renewable installations, or managing complex global projects.
