What wermke spring manufacturing does

Wermke Spring Manufacturing Company is a privately held, custom spring manufacturer founded in 1953 and headquartered in Fenton, Missouri, in the St. Louis metro. The company designs and produces a broad catalog of custom metal springs and wire-formed components, including compression, extension, torsion, spiral, power, and die springs, plus spring clips, spring washers, wire forms, and trailer ramp springs. Production capability spans round wire from .004" to 1.250" diameter and metal strip from .005" to .500" thickness, across materials such as stainless steel, chrome silicon, brass, beryllium copper, titanium, Inconel, Monel, phosphor bronze, and music wire. Manufacturing is performed on CNC spring coiling machines and Four Slide machines, supported by computer-aided spring engineering software and a proprietary cross-reference database of ASTM, SAE, AMS, MIL, DIN, and JIS wire specifications. Order volumes range from a single prototype to millions of pieces, with standard lead times of 2-4 weeks and rush delivery available.

The company serves an industrial customer base across six primary verticals — industrial manufacturing, automotive, medical devices, aerospace, military & defense, and appliances — and explicitly names Fortune 500 corporations as well as small companies among its buyers. All production runs under an ISO 9001:2015 certified Quality Management System, with compliance to Spring Manufacturers Institute standards, MIL-SPEC and DFARS for defense work, and access to a NADCAP-approved partner network for aerospace heat treating, plating, finishing, and inspection. Full material certification and traceability documentation are filed with every order.

Wermke operates a sales-led, direct-distribution model with no disclosed third-party resellers. Pricing is quote-based, driven by part specifications, material selection, quantity, and finishing requirements; customers engage via a phone-based inside sales line or online quote request forms. The firm has no public app, no public API or SDK, and no software product revenue. The company is privately held with no disclosed funding rounds, ownership changes, or M&A activity since founding, and it does not disclose revenue, headcount, or management roster publicly.
