What oem manufacturing & sales does

Monroe OEM is a privately-held custom component manufacturer and global sourcing partner headquartered in San Diego, California, serving OEMs and industrial buyers across multiple industrial verticals. Founded in 1988 in Los Angeles and relocated to San Diego in 1991, the company has operated as Monroe OEM, LLC since being acquired by OneMonroe in 2024. Its core offering is custom-engineered metal, plastic, and rubber components sourced and manufactured globally for end-markets including automotive, appliance, electrical/electromechanical, healthcare/medical, HVAC, communications, consumer products, sensors/controls, solar, and pool/spa.

The product portfolio spans roughly 16 component categories: industrial fasteners, threaded inserts (via subsidiary Inserts International, founded 1998), precision stampings, springs, shafts, extrusions, castings, machined components, custom molded rubber parts (via subsidiary RPS, founded 2016), magnets, wire forms, contacts and terminals, sub-assemblies, and bag kitting services. Manufacturing is anchored in Asia through wholly-owned subsidiary Hip Hing (acquired 2010), with production in Dongguan and a recently expanded Shaoguan facility, plus a new Vietnam plant opened in Hanoi in 2025. U.S. operations include a 20,000+ square foot headquarters and warehouse in San Diego operating as a certified Foreign Trade Zone, enabling duty deferral and tariff mitigation on imported components. Quality certifications include ISO 9001:2015 at the corporate level and IATF 16949 capability through Hip Hing.

Revenue is generated primarily through project-based, quote-driven manufacturing fees on multi-year contracts across component categories, supplemented by FTZ services, sub-assembly and kitting work, and value-added logistics and inventory management. Go-to-market is enterprise field sales targeting OEMs and contract manufacturers via an RFQ process (drawings, specs, and quantities submitted through the website), followed by engineering review, supplier sourcing, cost analysis, and formal quotation delivered within one business day. The company offers application engineering support including design assistance, cost-reduction consulting, and component standardization.
