Contract Manufacturing

OEMs and contract manufacturers differ mainly in terms of control, intellectual property ownership, and design responsibility. An Original Equipment Manufacturer (OEM) produces products based on a client’s exact design, with the client keeping ownership of the brand and intellectual property. In comparison, a Contract Manufacturer (CM) typically manufactures parts or complete products according to the client’s specifications, while the client keeps control over the design and production requirements. In many situations, contract manufacturing is part of an OEM relationship, where the CM acts as the production partner or factory, and the client is the OEM.

Quality and compliance are at the core of everything we do at Rosti Group. All 12 of our manufacturing facilities operate under internationally recognized certifications, including ISO 9001, ISO 13485 (medical), ISO 14001, and ISO 50001, ensuring rigorous standards for quality, sustainability, and energy management.

Our teams follow robust quality assurance processes, including advanced product validation, in-line inspections, and traceability systems to guarantee consistency and reliability across every production run. For highly regulated industries such as medical devices, automotive, and consumer goods, we ensure strict adherence to industry-specific standards and regulatory requirements.

Through continuous improvement programs, data-driven monitoring, and close collaboration with our customers, we deliver products that not only meet but often exceed expectations for quality, safety, and compliance.

Yes. At Rosti Group, our support goes far beyond plastic injection molding. Our Plastic Contract Manufacturing services offer complete design and engineering solutions, helping customers turn ideas from concept all the way to production.

Our teams work with you at every stage of the product lifecycle — from the initial design for manufacture (DFM), prototyping within 72 hours, and material selection, to tooling, testing, and full-scale production. By combining advanced simulation, rapid prototyping, and in-house engineering expertise, we make sure your products are optimized for performance, cost efficiency, and sustainability.

This end-to-end approach not only speeds up time to market, but also reduces risks, waste, and costs throughout the supply chain.

Rosti operates 12 state-of-the-art production facilities strategically located across Europe, North America, and Asia. This global footprint enables us to manufacture close to your end markets, helping to reduce lead times, optimize supply chains, and support your sustainability goals. By tapping into the full range of our plastic injection molding capabilities at any of our sites, you benefit from consistent quality, efficiency, and innovation worldwide.

The benefits of this approach include faster time to market, the ability to navigate economic challenges with greater flexibility, and opportunities to reduce costs through optimized production and logistics—helping you stay competitive in a rapidly changing marketplace.

From the early stages of our contract manufacturing process, sustainability is a core part of our discussions with the design and innovation teams to make sure we can identify ways to help you lower your environmental impact.

We are continuously investing to ensure every aspect of our business operations is helping reduce Rosti’s environmental impact, which is reflected throughout all areas of our contract manufacturing services.

We offer sustainable and recyclable material options during the design phase, and use energy-efficient equipment. By adopting automated and lights-out production, we are able to move away from traditional manufacturing methods, improving efficiency in material use and reducing waste.

When we plan the logistics and delivery of a finished product, packaging is an essential part of transporting high-quality goods. Our Contract Manufacturing team helps customers choose lightweight, returnable, or recyclable packaging to minimize waste and emissions while maintaining quality standards.

Contract manufacturing occurs when a company partners with a specialized manufacturer to produce specific components or products for a determined period of time. Think of it as outsourcing production to experts who can deliver exactly what you need, exactly when you need it.

In a typical arrangement, a contract manufacturer produces parts, components, or even complete products according to the client’s specifications. These items are then used by the client in their own manufacturing process or included in their final products. Many contract manufacturers operate as third-party specialists, either focusing entirely on contract work or supplying products to several companies.
