Romay

What Romay does

Romay is a Swiss-headquartered manufacturer of advanced composite components and sub-assemblies, founded in 1946 in Oberkulm and currently operating four manufacturing sites across Switzerland, Poland (Stanowice and Jelcz-Laskowice), and China (Qingdao), with 750–770 professionals in the standalone unit and 1,500+ within the broader group including sister company INSTYTUT MECHANIKI. Following the 2021 acquisition of ROMAY AG by KOMPOZYTY Sp. zoo and a 2025 rebrand that unified the group under the ROMAY name, the company functions as a single-source contract supplier to global OEMs in four end markets: public transport (rail vehicle interior/exterior cladding, door entrance areas, window panels), healthcare (MRI/CT scanner enclosures, laboratory diagnostic equipment casings), power generation (insulation components for 210–950 MW generators), and industrial machinery (cladding for vending and dispensing equipment).

The technical core spans multiple thermoset and thermoplastic processes, including SMC/BMC hot pressing across 15 production lines with 200–2,500 ton closing forces, rigid PUR reaction injection moulding on 7 tool carriers for parts up to 25 kg, vacuum thermoforming up to 2,700 x 1,800 x 1,000 mm, LRTM/vacuum infusion, and filament winding for cylindrical components up to 3.5 m diameter and 4,000 kg. In-house surface treatment includes robotic and manual painting plus screen, pad, and digital printing; assembly is supported by EN 17460 Class A1 certified bonding (load-bearing and safety-critical joints) and EN 15085-2 welding certification. Visible reference projects include ~350 individual components across 25 product groups for the Siemens Railjet, the Stadler FLIRT interior cladding system, Munich S-Bahn door entrance assemblies, the Siemens Cabral MRI housing, and Stryker surgical-navigation enclosures.

Revenue mechanics are project-based B2B with quote-driven pricing undisclosed publicly; the go-to-market is enterprise field sales to OEMs and system suppliers, with direct delivery of plug-and-play assemblies coordinated via just-in-time logistics and returnable packaging. Backlog visibility comes from multi-platform presence on Siemens, Stadler, and PESA rail platforms, with marketing concentrated on industrial trade shows (Swiss Plastics Expo 2026, InnoTrans 2026) and a website-led technical content presence rather than mass channels. Romay is privately held, with no external venture or growth-equity funding disclosed.

• Siemens Mobility GmbHcoreStrategic or Co-development Partner · 9 July 2025ROMAY collaborates with Siemens Mobility on the Mireo platform project. On July 8-9, 2025, ROMAY AG hosted type testing focusing on mechanical installation of formwork and paneling components for entrance and boarding areas. The collaboration includes First Article Inspection (FAI) preparation for the complete delivery scope. ROMAY also supplies Door Entrance Area assemblies for Munich S-Bahn project and completed the Siemens Cabral MRI platform housing and Railjet interior cladding.
• INSTYTUT MECHANIKIcoreStrategic or Co-development PartnerINSTYTUT MECHANIKI is the sister company of ROMAY within the industrial capital group. Together, the group employs over 1500 professionals. The acquisition of ROMAY AG by KOMPOZYTY (now ROMAY) Sp. zoo in 2021 created an international industrial group. INSTYTUT MECHANIKI provides stability and future-driven perspective for the combined entity.
