New operation is part of M&M’s multi-year expansion plans to better serve the global medical device industry.

EDISON, N.J., Oct. 21, 2026 /PRNewswire/ — M&M International (“M&M”), a leading manufacturer of precision-engineered stainless-steel tubing primarily serving the medical device market and other high-tech applications, today announced it will open a new manufacturing facility in the Greenpark free-trade zone in Coyol, Costa Rica. Currently under construction, the plant will expand M&M’s production capacity and diversify its manufacturing footprint, ensuring an enhanced supply chain for its customers. M&M is a portfolio company of Gainline Capital Partners.

Scheduled to open in the first quarter of 2027, the new facility brings M&M manufacturing closer to its customers in the U.S. and Latin America. “Opening our third manufacturing facility increases our agility and ability to meet the evolving needs of our customers around the world,” said Jeff Robertson, CEO of M&M. “We’re pairing over three decades of manufacturing expertise with the talented workforce we will be hiring in Costa Rica.”

Phase one of the new facility will encompass 40,000 square feet and will produce stainless steel medical tubing, a critical component of catheters, needles, robotics, and surgical instruments. “This new facility will be state of the art, providing all the various alloys, processes, and technical support for the challenging requirements our markets demand. As M&M continues to expand its reach and customer base, this new facility will be able to nearly double in size, providing additional capacity and processes to support our customers,” stated Robertson.

Founded 33 years ago, M&M is a leading producer of 300 series, Inconel 625 and 17-7 stainless-steel small-diameter tubing for medical devices and other high-precision applications. The construction of the new manufacturing facility follows M&M’s June acquisition of the South Korean stainless-steel tubing manufacturer KC Tech, which significantly expanded M&M’s manufacturing capabilities and broadened its product portfolio.
