What Custom Manufacturing & Engineering does

Custom Manufacturing & Engineering, Inc. (CME) is a privately held, women-owned (WBENC-certified) electrical and electro-mechanical contract manufacturer founded in 1996 and headquartered in a single facility in Pinellas Park, Florida. It designs and builds custom cable assemblies and wiring harnesses, power supplies (TPS, WRPS, benchtop AC-DC), circuit card assemblies (CCA/PCBA), box builds, and special test equipment including the ADTS 415F air data test set for which it is the largest supplier to the U.S. Air Force. Core manufacturing capabilities include an SMT assembly line (stencil printing, pick-and-place, reflow oven), UL508A panel building, and an A2LA-accredited ISO 17025 calibration lab supporting pressure and vacuum calibration.

The company generates revenue through a mix of custom hardware sales, build-to-print and design engineering services, calibration and maintenance/repair services, and integration & test services, with unit prices ranging from approximately $1.10 (ADTS fuses) to $5,100 (TPS800) per item and custom quoting for larger systems. GTM is hybrid: direct sales to U.S. government agencies and Fortune 500 customers in aerospace/defense, transportation, heavy equipment, and industrial electronics, complemented by a Weebly-powered e-commerce storefront for standard products (solar4POWER, SiteLites, accessories) and Thomas.net RFQ presence. Operating credentials include AS9100D, ISO 9001:2015, ISO 17025, UL508A, and IATF/TS 16949 compliance, with documented delivery of 20,000+ tactical power supply units and a 0.03% warranty return rate on an 8-year contract.

The company is founder/owner-operated under President and CEO Dr. Nancy Crews, with no disclosed venture capital or private equity backing and no disclosed M&A, restructuring, or leadership transitions in the available materials. CME has maintained continuous operation since founding, including through COVID-19, and was recognized in 2019 as a GrowFL Florida Companies to Watch award winner. Customer concentration is anchored on aerospace and defense (especially the U.S. Air Force), with diversification initiatives into consumer-facing solar and lighting brands via its e-commerce channel.
