Hutchinson Technology Incorporated (HTI) Hutchinson Technology Incorporated, a subsidiary of TDK Corporation since its acquisition in 2016, designs, develops, manufactures, and supplies precision-engineered micro actuation components and suspension assemblies primarily for hard disk drives and advanced technology applications; its core offerings include high-precision suspension assemblies for all sizes and types of hard disk drives, intricate metal-etched parts, chemically etched blades, ceramic features on metal substrates, miniaturized electromechanical sensors for surgical instruments, and custom precision components for medical devices, aerospace, defense, and electronics industries. The company operates globally with manufacturing facilities in Thailand, the United States including Minnesota headquarters established in 1964, and development labs supporting rapid prototyping, design for manufacturing, and component miniaturization to reduce customer time to market. HTI emphasizes quality, continuous improvement, and innovation in materials science and precision processes to serve demanding markets requiring reliable, high-performance solutions. In recent developments, TDK divested HTI's medical business unit to Resonetics in 2021 to focus on core competencies, followed by the closure of its Eau Claire, Wisconsin plant in 2024 with significant layoffs, and the subsequent sale of that 750,000-square-foot facility to TTM Technologies Inc. in July 2025 as part of strategic realignment and operational optimization.
