ASSOCIATED SPRING US, LLC

ASSOCIATED SPRING US, LLC specializes in the precision manufacturing of high-performance springs, wire forms, and related metal components for industrial and defense applications. Leveraging deep expertise in cold and hot coiling, heat treatment, surface finishing, and dimensional metrology, the company delivers mission-critical parts that meet stringent aerospace, automotive, and industrial engineering standards. Their technical capabilities include custom alloy selection, stress relieving, shot peening, and automated inspection systems to ensure consistent performance under extreme load and environmental conditions. Differentiators include tight tolerance control, rapid prototyping, and engineering support for design optimization—enabling clients to reduce assembly complexity and improve system reliability. Award history is not available to confirm specific agency engagements, so no definitive patterns of federal partnership can be identified. The absence of recent contract data precludes confirmation of direct work with any government department or defense contractor. The contractor’s primary NAICS code, 332613, corresponds to Machine Shop; Turned Product; and Screw, Nut, and Bolt Manufacturing, indicating a focus on precision metal component fabrication. In practice, this translates to producing engineered spring assemblies and custom wire-formed parts used in mechanical systems requiring high fatigue resistance and repeatability. The company occupies a niche in the industrial supply chain as a Tier 2 or Tier 3 supplier to manufacturers requiring certified, low-volume, high-reliability components. ASSOCIATED SPRING US, LLC is structured as a small business under the 2L entity classification and is headquartered in Milwaukee, Wisconsin. The company holds no active government certifications such as 8(a), HUBZone, or WOSB, and operates as a privately held manufacturer with a localized production footprint. Its market positioning centers on technical precision and responsiveness within the industrial component supply base, serving customers who prioritize quality control and engineering collaboration over scale.
