GfM Gesellschaft für Micronisierung mbH was founded in 1985 in Oldenburg, Germany, by Günther Rasack (1st generation) and partners as a family-run milling service for the chemical industry. Then, under the leadership of Ante Rasack (2nd generation), the company quickly built a reputation for reliability and expertise in particle size reduction with a clear vision, a strong technical foundation, and a commitment to quality. GfM has since extended its technical capabilities, infrastructure, and workforce to meet growing demands in process design, particle controls, high safety standards, and regulatory compliance.
