What Rosti Group does

Rosti Group is a Sweden-founded global plastic injection moulding and contract manufacturer headquartered in Malmö, established in 1944 and operating as a wholly-owned subsidiary of the Nordic investment company Nordstjernan. The company operates 13 manufacturing sites across Europe (Sweden, Germany, Poland, Romania, UK, Turkey), North America (North Carolina, Utah, Wisconsin), and Asia (China, Malaysia, India), with a Singapore-based Asia Integrated Solutions hub inaugurated in May 2026 to coordinate pan-Asian operations. Rosti employs approximately 2,500+ people globally and serves enterprise OEMs and Tier 1 suppliers across three primary verticals: medical and healthcare (ISO Class 8 cleanroom production, ISO 13485-certified), consumer appliances and goods, and industrial and engineering (including automotive, IATF 16949-certified).

The company's core offering spans precision plastic injection moulding (standard, overmoulding, 2K multi-shot, LSR, micro, injection blow moulding, and in-mould decoration/labelling), full contract manufacturing (assembly, testing, packaging, supply chain management, logistics), and specialised medical device moulding and assembly. Differentiated technical capabilities include patented lights-out manufacturing at the Bunsen Drive facility in Utah, scientific moulding using RJG eDart process controls, in-house rapid prototyping via Carbon DLS additive manufacturing, and the ability to transfer validated tooling and production between regions without re-qualification risk. The company holds a broad certification stack (ISO 9001, 13485, 14001, 45001, 50001, IATF 16949, FSSC 22000, BRCGS, EcoVadis, RBA, ISCC, UL, FDA/IMS) and has been progressively transitioning sites to 100% renewable energy.

Rosti generates revenue through long-term, enterprise-grade OEM manufacturing contracts, with project- and volume-based pricing (not publicly disclosed). GTM is engineering-led enterprise field sales targeting product-owning OEMs and Tier 1 suppliers, with cross-functional engagement from early design stages (DFM, NPI, rapid prototyping) through to global multi-site production. Approximate annual revenue is €500M, with the recently opened India operation expected to add €25-30M. Marketing is predominantly B2B content- and event-led (whitepapers, case studies, MedTec China, Interplas, LinkedIn, YouTube, sustainability reporting), and the company operates exclusively through direct sales with no resellers or distributors.
