Rosti Group is building new ISO Class 8 cleanrooms at its Germantown, Wis., and Clearfield, Utah, facilities to expand its North American medical manufacturing footprint and reinforce its support of high-precision, regulated production environments.

The new Germantown cleanroom, currently under construction, encompasses more than 3,000 square feet and will support advanced medical and life sciences applications. The space will house a 300-ton injection molding press supported by two types of integrated automation, including bulk pack and layer tray pack automation, along with a freestanding overhead crane to support efficient tool changes and production flexibility. The cleanroom includes a dedicated airlock, pass-through, and gowning areas to meet stringent cleanliness and process requirements.

The Germantown project represents a significant operational effort, requiring the relocation and reconfiguration of approximately 15 presses and associated material handling systems within a compressed timeframe. The work was completed largely in-house by Rosti’s engineering and maintenance teams, ensuring minimal disruption while creating capacity for current and future cleanroom manufacturing cells.

“This project was a true cross-functional effort,” said Andy Hoffman, manufacturing engineering manager at Rosti North America. “From relocating presses and expanding material handling systems to designing the cleanroom layout and automation, the team accomplished an incredible amount in a short period of time. The result is a highly capable, flexible cleanroom environment that supports our customers’ current needs and allows room for future growth.”

The Germantown cleanroom was developed in partnership with Encompass Solutions, which served as the building partner and project manager for the cleanroom enclosure and infrastructure. The space is expected to be operational by early April, with production ramping up later that month.

In parallel, Rosti is preparing to launch a second ISO Class 8 cleanroom at its Clearfield, Utah, facility. The Utah cleanroom, planned at approximately 1,400 square feet, will be built within existing warehouse space and is designed to support up to five smaller injection molding presses. The project is being developed for a new medical customer and includes capacity for future expansion as program requirements evolve.

“The Utah cleanroom gives us additional flexibility to support high-value, regulated medical programs,” Hoffman added. “Medical manufacturing brings unique technical and quality requirements, and these investments allow us to meet those expectations while creating opportunities for long-term, stable growth.”

Both cleanroom projects reflect Rosti North America’s strategic focus on medical and life sciences manufacturing, a segment that continues to demand precision, regulatory compliance, and reliability. By expanding cleanroom capacity in both Wisconsin and Utah, Rosti is positioned to support customers with scalable solutions across multiple regions while maintaining consistent quality and operational excellence.
