From One Site to Four: How Rosti’s Global Footprint Strengthened a Long-Term Injection Molding Partnership

At Rosti, providing high precision plastic injection molding and building long-term partnerships with our customers are at the heart of how we work.

Our 15-year collaboration with one of our global customers exemplifies how shared goals and a truly international network can drive growth, efficiency, and sustainability.

Global Plastic Injection Molding

We have been injection molding for this customer in China for over a decade, our partnership has now expanded across four Rosti sites, extending to Turkey, Germany, and Romania, supporting a diverse portfolio of brands and markets.

This expansion highlights the customer’s confidence in our capabilities and the strength of our combined global and local teams.

As new legislation encourages localisation of production in key markets, Rosti has supported our customer in establishing manufacturing closer to their end users. This strategic move has reduced environmental impact, improved operational agility, and minimised risks related to tariffs and global supply chain disruption.

Delivering consistency through global teams

A key factor in this success is Rosti’s independent commercial structure. Free from single-site targets, our commercial team provides impartial advice, ensuring every project is placed in the location that best fits the customer’s technical, commercial, and sustainability needs.

Current projects include food packaging in Turkey, manufacturing for the baby food industry in Germany, and an industrial medical component in Romania. Each benefits from Rosti’s tooling expertise, process optimisation, and trusted delivery – ensuring consistency and quality across every site.

Following 18 months of development, all new projects are now moving into full production, more than doubling Rosti’s business with this customer to exceed €10 million.

By combining global reach with local execution, Rosti continues to help customers achieve supply chain resilience, operational efficiency, and sustainable growth — proving that partnership and presence go hand in hand in today’s connected manufacturing world.
