What Phillips Service Industries does

Phillips Service Industries (PSI), founded in 1967 and headquartered in Plymouth, Michigan, is a privately held industrial holding company operating four wholly-owned subsidiaries: PSI Repair Services, PSI Semicon Services, RAC (Repairable Asset Control), and Sciaky, Inc. The group positions itself as a collection of technology-driven companies delivering repair, manufacturing, and MRO solutions for land, sea, air, and space applications, with stated sales and representation on every continent.

The portfolio centers on independent repair and refurbishment services for electronics, hydraulics, robotics, precision mechanical assemblies, and advanced semiconductor manufacturing equipment, alongside Sciaky's proprietary electron beam (EB) and resistance welding systems. Its most differentiated technology is EBAM (Electron Beam Additive Manufacturing), a trademarked, large-scale industrial metal 3D printing process capable of depositing over 12,000 lbs of titanium annually. In 2021, Sciaky received a NASA Small Business Innovation Research (SBIR) award to develop machine-learning algorithms for defect detection in titanium parts produced via EBAM, signaling an embedded quality-control AI layer within that process.

PSI monetizes through professional service fees (repair and refurbishment), hardware sales (EB and resistance welding systems, EBAM-related offerings), and MRO parts management contracts under RAC. Distribution combines direct enterprise field sales by the operating subsidiaries with a global channel of in-country representatives and sales agents. Served end markets include aerospace, defense, semiconductor manufacturing, automotive, energy, and medical, spanning the United States, Europe, Australia, and the Pacific Rim.
