Micro-Tronics

What Micro-Tronics does

Micro-Tronics, Inc. is a privately held precision manufacturing company founded in 1976 and headquartered in Tempe, Arizona. The company operates from a single facility at 2905 South Potter Drive, with a stated workforce of more than 150 engineering, manufacturing, and customer service experts (though the firmographic headcount range is 11-50). Its core business is contract precision manufacturing, organized around two interrelated capability sets: electrical discharge machining (Wire EDM, Sinker EDM, Fast Hole EDM — supported by 26 Sinker, 18 Wire, and 7 Fast Hole machines) and elastomer/rubber manufacturing (compression, transfer, and injection molding with 30-400 ton press capacity, plus proprietary rubber-to-metal bonding and Kapton molding). Adjacent capabilities include 2- to 5-axis CNC milling, laser part marking, multi-level mechanical assembly, and in-house tooling.

The company serves enterprise customers in Aerospace, Defense, Medical, Satellite, Industrial, Automotive, and Electronic end markets, with Aerospace/Defense and Medical identified as primary verticals. Micro-Tronics holds AS9100 Rev D with ISO 9001:2015, dual Nadcap certifications (Nonconventional Machining and Elastomer Seals, the former valid through August 2027), ITAR registration with the U.S. Department of State, and FAA/DOT Anti-Drug and Alcohol Misuse Prevention Program compliance — a certification stack that materially restricts the field of qualified suppliers for defense prime contractors.

Revenue is generated through project-based, quote-priced B2B contracts (RFQ submitted via the company website) with multi-year cadence and ship-to-stock / just-in-time delivery programs. The go-to-market is direct enterprise field sales with no public pricing. In January 2026, Micro-Tronics was acquired by Arxis, a publicly traded A&D manufacturing platform, with transaction terms undisclosed; the company continues to operate as a subsidiary. Leadership consists of Co-CEO Johnny Marusiak, executive Charlie Marusiak, and CFO Kevin Hesse, with the Marusiak family providing operational continuity across the company's 50-year history.
