Do you offer design and engineering support?

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.
