Private equity firm buys Summit tooling, molding businesses Ryan Martin, CEO of Fathom. Chicago-based private equity firm Core Industrial Partners has acquired Summit Tooling Inc. and Summit Plastics Inc. of McHenry, Ill., for its portfolio company Fathom. Fathom provides on-demand manufacturing in 14 processes and six additive manufacturing technologies across its national footprint, which includes about 100 industrial-grade 3D printing machines for mostly plastics but also metal. The Summit acquisition increases Fathom's in-house tooling capabilities and expands its injection molding capacity, which will help the acquirer answer calls for on-shore injection molding, according to Fathom CEO Ryan Martin. "We saw really tremendous growth in 2020 across our additive business, CNC machining, injection molding, tooling and urethane casting machining," Martin said. "Many times we had to leverage our supply chain partners for tooling to injection mold parts as our internal capacity and capabilities were limited domestically. We saw this as an opportunity to offer a more comprehensive solution to our customers."
