What Mountain Manufacturing Technologies does

Mountain Manufacturing Technologies, LLC (MMT) is a precision contract manufacturer founded in 1988 by Tom Berg and headquartered in Lino Lakes, Minnesota. The company specializes in machining specialty medical wire and tubing components — primarily catheter mandrels, guide wires, core wires, and micro-machined implantable components — for Tier 1 medical device OEMs, contract manufacturing organizations, and early-stage medical device companies. Its end markets are interventional delivery systems, cardiovascular and structural heart devices, electrophysiology, and advanced surgical robotics.

MMT operates a fully integrated in-house manufacturing platform spanning precision centerless grinding (Mountain Grinding Division, tolerances to ±0.0001 inches), multi-axis Swiss and mill-turn machining, EDM wire and sinker, custom mandrel fabrication (D-shaped, hollow-core, multi-lumen, 3D-formed), wire and tube bending, swaging, laser marking, passivation, and Halar 6014 electrostatic powder coating. It is ISO 13485:2016 certified and an FDA Registered Manufacturing Facility. The company serves customers through a quote-based enterprise field-sales motion, direct email/phone intake, and an OnDemand Rapid Prototyping program that delivers machined parts in 2-4 weeks.

In October 2022 Vance Street Capital acquired MMT to complement its existing portfolio company Wytech Industries. In April 2024 MMT and Wytech jointly acquired Silvertip & Associates to create a Minneapolis grinding division. In August 2025 the company announced a new Blaine, MN manufacturing facility more than doubling its square footage. MMT and Wytech collectively produce over 83 million components annually.
