Dover Corporation, the U.S.-based parent company of the Maag Group, has completed its acquisition of Sikora AG, a Germany-based manufacturer specializing in advanced measuring and control technology for industrial applications, particularly in the plastics sector. The acquisition, initially announced in May 2025, marks a strategic step in Maag’s continued global expansion and innovation drive.
With the transaction finalized, Maag and Sikora will begin integrating their technologies and operations to capitalize on complementary strengths and geographical synergies. The collaboration aims to enhance their joint capabilities in delivering cutting-edge, customer-centric solutions across global markets.
“We are very pleased about this partnership,” said Ueli Thuerig, president of the Maag Group. “By combining our strengths and expertise, we are ideally positioned to create additional value for our customers, drive innovation in a targeted manner, and promote the long-term growth of both companies.”
Sikora will now operate within Dover’s Pumps & Process Solutions segment, alongside Maag. Maag, a Swiss-headquartered company, designs and manufactures equipment for the production and processing of plastics. Its manufacturing footprint spans Switzerland, Germany, Italy, the United States and China, with additional service centers and sales offices in key markets such as France, Taiwan, Malaysia, India, Thailand, and Brazil.
Over the past few years, Maag has followed an aggressive acquisition strategy to strengthen its portfolio and geographic reach. Recent additions include AMN DPI, a French tooling company, and Witte Pumps & Technology, a German manufacturer known for high-precision pumps.
Founded in Bremen, Germany, Sikora has built a strong reputation for its precision technologies, including the Purity Scanner Advanced, a system for inspecting and sorting plastic pellets, flakes and films. The company also offers millimeter-wave-based systems for measuring diameter, wall thickness, ovality, and sagging in large plastic pipes and tubes. These innovations help manufacturers reduce raw material usage and scrap production, contributing to lower carbon emissions.
“We are proud to be officially part of the Maag family now,” said Christian Frank, CEO of Sikora. “This partnership goes far beyond standard cooperation—it is based on a shared commitment to innovation, entrepreneurial spirit and sustainable action, which form the foundation for long-term success. It marks an important step in our shared future, opens up a wide range of opportunities, and strengthens our ability to develop innovative solutions.”
Sikora reported €100 million in revenue in 2024 and celebrated its 50th anniversary in 2023. The company operates multiple subsidiaries and representative offices across Europe, Asia, and the Americas, including in Germany, Brazil, China, India, Japan, the U.S., and more. Frank noted that the acquisition brings enhanced stability and opportunity for Sikora’s 400 employees.
