Master Spring

What Master Spring does

Master Spring & Wire Form Co. is a custom spring and wire form manufacturer founded in 1945 and headquartered in Roselle, Illinois. The company produces made-to-order compression springs, extension springs, torsion springs, and precision wire forms from round wire, with wire diameter capabilities spanning 0.006" to 0.500" depending on product type. Manufacturing is performed on all-servo high-speed CNC coiling and 3D-bending machines equipped with in-line laser sensors, touch probes, Keyence instant measurement systems, and LED 3D camera inspection, supported by Spring Manufacturers Institute design software, SOLIDWORKS CAD, MasterCAM, and JobBOSS ERP. The firm's value proposition centers on producing complex, hard-to-make parts that other manufacturers decline to quote, backed by 75+ years of accumulated engineering expertise and ISO 9001:2015 certification.

Master Spring operates a B2B OEM sales motion with quote-based pricing, a $2,000 minimum purchase order, split shipment options, and blanket order arrangements requiring completion within 12 months. Credit terms are offered subject to approval, with a 1.5% monthly late payment charge. The firm explicitly prefers medium-to-high quantity OEM production over prototype-only or solo-inventor work. It serves eight industry verticals: commercial lighting, electronics, filters, fishing tackle and lures, hardware and fasteners, construction power tools, renewable energy, and spraying equipment and pumps. The company holds no public listings, has no known parent, no venture capital backing, and is privately held, with no disclosed leadership team, M&A activity, or funding rounds in the source data.

• Diamond Wire Spring Company: Diamond Wire Spring manufactures custom compression, extension, torsion, and wire-form products. It is a direct peer because it offers the same core spring categories to industrial customers.
• M & S Spring Company: M & S Spring produces custom springs, wire forms, stampings, and assemblies for industrial and OEM applications. It is comparable to Master Spring’s made-to-order spring and CNC wire-form manufacturing model.
• Century Spring Corp. Century Spring offers stock and custom springs, including compression, extension, torsion, and specialty products. It is comparable because it competes for customers needing spring components, though its catalog model is more prominent.
• Hardware Products Company: Hardware Products Company manufactures custom springs, wire forms, and related metal components for OEM and industrial uses. It is comparable because its custom spring and wire-form offering maps closely to Master Spring’s core products.
• Newcomb Spring Corp. Newcomb Spring manufactures custom springs, wire forms, and metal stampings for OEM and industrial customers. It is highly comparable because it competes directly in custom precision spring and wire-form production.

Broad incumbents

• MW Components: MW Components manufactures precision components including custom springs, fasteners, bellows, and other engineered metal parts. It overlaps strongly in custom spring manufacturing but is a broader incumbent with a wider precision-components portfolio.
• Associated Spring RAYMOND: Associated Spring RAYMOND provides engineered springs, gas springs, and precision metal components. It is comparable as an established spring and engineered component manufacturer serving OEM applications, though with a broader product range.

Regional players

• Katy Spring & Mfg. Katy Spring & Mfg. is a custom spring manufacturer serving industrial customers with compression, extension, torsion, and wire-form products. It is comparable by offering, but is more regionally anchored around the Texas/Gulf Coast market.
