Milacron, a plastics processing solutions provider backed by CCMP Capital Advisors, has agreed to acquire Mold-Masters, a global hot-runner manufacturer backed by 3i Group, for CAD975 million. Headquartered in Georgetown, Canada, Mold-Masters designs and manufactures hot-runner systems, temperature controllers and auxiliary equipment for the plastics industry. Cincinnati-based Milacron's services include plastics-processing technologies, metalworking fluids and precision machining. The combined entity will merge the two companies' complementary product lines and offer clients a broader portfolio of products and services. The transaction is expected to close in the first half of 2013. 3i Group disclosed a 2.6x return on its October 2007 investment in Mold-Masters.
