Coating Place has the most comprehensive and modern facilities dedicated to Wurster fluid bed coating for specialty chemical contract manufacturing.

Coating Place—Sauk City is a 110,000 ft² facility located in Sauk City, Wisconsin, 25 miles northwest of the headquarters in Verona, Wisconsin. This facility is equipped with multiple 4600 Wurster fluid bed coating units which manufacture batch sizes of up to 800 Kg per unit, as well as model 400 and model 1200 research coating units. All Coating Place Wurster fluid bed units are capable of handling aqueous or organic solvent-based coating systems. Each unit is equipped with the latest technology in emissions control. Coating units are built to control process air humidity, providing consistent and reproducible processing year-round. This facility is capable of manufacturing custom industrial and food-grade GMP products and offers controlled ambient storage areas for sensitive raw materials. Our engineering team designed the Coating Place–Sauk City facility to ensure flexibility in accommodating future fluid bed expansion, in addition to quality control laboratories.


Our Sauk City manufacturing facility has a long history as the Wisconsin Creamery Company Cooperative (WCCC). Built in 1948, the WCCC produced butter, cheese, powdered milk, and handled Grade ‘A’ milk. Eventually, through mergers with other local dairy cooperatives, WCCC became the Wisconsin Dairies Cooperative and was acquired by Foremost Farms USA. The Sauk City Creamery ceased its milk and cheese production in the 1980’s, but the 65,000 ft² facility continued to function as a milk transfer station through the late 1990’s. In the early 2000’s, Foremost Farms USA sold the facility. The building was stripped of much of its interior and equipment then converted to a storage warehouse.

Coating Place acquired the building in January of 2012, and the facility was immediately outfitted for Wurster fluid bed coating units, packaging lines, and analytical laboratory support. This provided the opportunity for the manufacturing of specialty chemical products to move from its headquarters in Verona to the Sauk City facility. In 2019, the facility was converted to GMP food-certified manufacturing for animal and human nutrition products.
