Southwest Industrial Sales

What Southwest Industrial Sales does

Southwest Industrial Sales, LLC is a privately held U.S. contract manufacturer founded in 2008 and headquartered in Chandler, Arizona. The company operates a 30,000 sq. ft. ISO-certified production facility delivering vertically integrated manufacturing services to OEMs, engineers, and industrial buyers in regulated end markets including medical and life sciences, aerospace, defense and government, and industrial automation. Its workforce is sized at 51-100 employees and the firm is organized as an Arizona LLC with no disclosed institutional investors or parent company.

The company's product portfolio is organized around five service pillars: UL 508A-certified industrial control panel design, build, and testing; electromechanical and mechanical assembly with wire harnessing, PCB installation, and cleanroom-ready options; precision machining including CNC milling, Swiss machining, and wire EDM; sheet metal fabrication and welding; and supply chain services spanning vendor-managed inventory (VMI), kitting, just-in-time delivery, and offshore manufacturing coordination, with 3D scanning as an add-on service. A documented visual inspection process (SIS-027) underpins quality control. The compliance stack includes UL 508A, AS9100, ISO 9001, CMMC Level 1 & 2, ITAR registration, and ISO 13485-aligned processes, which collectively qualify the firm for aerospace, defense, and medical-adjacent work.

Southwest Industrial Sales generates revenue primarily through custom, quote-based project pricing on one-time build-and-deliver work, supplemented by recurring managed-services revenue from VMI and kitting programs. Pricing is engineering-led and requires Bill of Materials, 2D/3D CAD files, and certification specifications, with a stated 24-hour quote response. The go-to-market motion is direct enterprise field sales with assigned account managers and personal-cell-phone accessibility; no channel partners, resellers, or marketplace presence is used. Industry mix is disclosed as approximately 30% medical, 20% aerospace, 10% oil & gas, 10% automotive, and 30% other commercial, with Saginaw Control named as a strategic OEM customer.
