Gainline Capital Partners announced that its portfolio company M&M International has acquired KC Tech. Financial terms of the transaction were not disclosed.
M&M International is a manufacturer of precision-engineered stainless-steel tubing primarily serving the medical device market.
KC Tech is also a manufacturer focused on the medical device market and has been a strategic partner to M&M.
The acquisition will expand M&M’s manufacturing capabilities and broaden its product portfolio.
KC Tech adds a complementary line of larger-diameter tubing, strengthening M&M’s ability to provide specialized tubing solutions for medical device customers.
M&M and KC Tech have worked together for more than a decade, giving M&M familiarity with KC Tech’s manufacturing processes, management team, and employees.
KC Tech’s team will become part of M&M following the acquisition.
The transaction is part of M&M’s multi-year strategy to grow organically and through acquisitions.
Founded 33 years ago, M&M produces 304, 316-grade, and 17-7 stainless steel small-diameter tubing for medical devices and other high-precision applications.
Gainline acquired M&M in July 2024 and hired an experienced U.S.-based management team to support the company’s next phase of growth.
M&M is headquartered in Edison, New Jersey, and operates manufacturing facilities in South Korea.
The company serves a global customer base with precision small-diameter metal alloy tubing for demanding medical and high-tech applications.
Gainline Capital Partners is a private equity firm investing in U.S.-based middle-market companies, with a focus on established growth-oriented businesses and first institutional capital partnerships.
