What Springmasters does

Springmasters operates as a brand within MW Components, a US-based precision metal component manufacturer and wholly-owned subsidiary of the MW Industries (MWI) holding company. The platform produces springs, fasteners, bellows, couplings, shims, threaded inserts, and precision components across eight specialized sub-brands including Century Spring, Greer Springs, Matthew Warren Spring, Maudlin, Helical Products, Maryland Precision Spring, Engineered Spring Products, and Hyperco. Manufacturing processes span hot wound and cold wound spring forming, electroforming, hydroforming, edge-welding, and cold forming of micro-components, supported by proprietary furnace technology for hot wound springs up to 3.125 inch bar diameter and ISO 9001, AS9100D, ISO 13485, DFARS, ITAR, MIL-SPEC, API 20E, FAA, and NASA compliance. The platform operates 20+ manufacturing facilities globally with a catalog of 40,000+ in-stock designs and 100+ engineers and design specialists.

The company serves four primary verticals: aerospace (commercial and defense OEMs requiring AS9100D and FAA compliant parts), military and defense (MIL-SPEC, DFARS, ITAR, QSLM compliant components for armored vehicles, antenna systems, and military hardware), medical device (ISO 13485 certified 316 stainless steel springs, pharmaceutical screws, implantable components, surgical instruments, and electroformed bellows for medical vision systems), and energy/oil and gas (Elgiloy and MP35N severe-service springs rated to 850°F for upstream, midstream, and downstream applications). Additional segments include automotive (IATF 16949 certified), industrial distribution via McMaster-Carr, and motorsports via the Hyperco NASCAR Cup Series partnership. Notable enterprise customers include Emerson, Knorr-Bremse, Caterpillar, Cardinal Health, McMaster-Carr, and BISCO.

Revenue is generated through three streams: standard/stock product sales from the 40,000+ item catalog, custom manufacturing services with no minimum order quantity for prototyping through multi-million part production runs, and engineering and design consulting. The go-to-market combines a direct enterprise field sales motion with a self-service e-commerce storefront supporting CAD downloads and real-time inventory, complemented by an inside sales team responding to quote requests within 1-2 business hours. The company is privately held with no external funding rounds disclosed and operates as a roll-up platform that has integrated multiple legacy manufacturers under the MW Components umbrella.
