Rosti North America Expands Medical Manufacturing Capabilities with New ISO Class 8 Cleanrooms in Wisconsin and Utah

New cleanroom investments strengthen Rosti’s support for regulated medical and life sciences customers and position the company for continued growth.

We are excited to announce the upcoming opening of new ISO Class 8 cleanrooms at our Germantown, Wisconsin and Clearfield, Utah facilities. These investments expand Rosti’s medical manufacturing footprint in North America and reinforce the company’s commitment to supporting customers with high-precision, regulated production environments.

The new Germantown cleanroom, now under construction, covers more than 3,000 square feet and is designed to support advanced medical and life science applications. The space will feature a 300-ton injection molding press, supported by two types of integrated automation—including bulk packaging and layer tray packaging automation—as well as a freestanding overhead crane to enable efficient tool changes and flexible production. The cleanroom includes dedicated airlock, pass-through, and gowning areas to meet strict cleanliness and process standards.

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

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

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

At the same time, Rosti is preparing to launch a second ISO Class 8 cleanroom at its Clearfield, Utah facility. The Utah cleanroom, planned at about 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 room for future expansion as program requirements change.

“The Utah cleanroom gives us more 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 demonstrate Rosti North America’s strategic focus on medical and life sciences manufacturing—a segment that continues to require precision, regulatory compliance, and reliability. By expanding cleanroom capacity in both Wisconsin and Utah, Rosti can support customers with scalable solutions across multiple regions while maintaining consistent quality and operational excellence.
