Dynisco LLC, with fresh capital and new ownership, has purchased Alpha Technologies US LP, a company in Akron, Ohio, that makes laboratory instruments and data acquisition and analysis software for the rubber industry.
Franklin-based Dynisco makes pressure transducers and transmitters, screen changers, pelletizers and other equipment for plastics extrusion.
Boston equity firm Audax Group bought Dynisco on July 12 from Madison Capital Partners of Chicago. The Audax deal included an investment of $15 million in Dynisco from American Capital Strategies Ltd.
At the time, Audax, the majority owner, said it would look aggressively for acquisitions to build Dynisco.
American Capital Strategies announced Sept. 2 that it has invested another $14 million into Dynisco to support the acquisition of Alpha Technologies. Alpha equipment includes lab rheometers and software that collects and integrates data from both the lab and the production floor. The company has a global sales and service network.
``Alpha and Dynisco possess complementary technologies and strong shares in their respective markets,'' said American Capital Strategies' managing director, David Steinglass.
American Capital Strategies, based in Bethesda, Md., is traded on Nasdaq. The firm has invested more than $900 million so far this year, and $1.5 billion during the past 12 months.
