Spang Engineered Solutions

What Spang Engineered Solutions does

Spang Engineered Solutions (SES) is a business unit of Spang & Company, a diversified manufacturing conglomerate founded in 1894 and headquartered in Pittsburgh, Pennsylvania. SES designs and manufactures custom magnetic components — primarily inductors and transformers — using a broad range of coil winding methods (random, layer, Z, interleaved, section/sector, bank, progressive, and universal/basket-weave) to optimize performance for specific customer applications. The company operates five manufacturing facilities across the United States (Pittsburgh, Phoenix North, Phoenix West, McKinney) and China (Xiamen), with capabilities spanning design, prototyping, testing, and high-volume manufacturing.

SES's core product lines include custom inductors (large chokes, common mode chokes, DC chokes, filter and resonant inductors), custom transformers (SMPS, current, gate drive, signal, isolation, pulse, ferro-resonant, three-phase, autotransformers), finished magnetic assemblies (encapsulated, potted, RLC-filter modules), and RF/coaxial cable assemblies. The company serves six primary end-markets: electric vehicles, alternative energy, aerospace and defense, transportation, industrial power, and medical devices. Multiple facilities hold AS9100D aerospace certification, ISO 9001:2015 quality management certification, DDTC registration for ITAR compliance, and UL Electrical Insulation Systems certification (File E68030), positioning SES for mission-critical applications including avionics, radar, MRI systems, EV power electronics, and grid-scale energy conversion.

The business model is custom hardware sales: each component is engineered to customer specifications via direct enterprise engagement, with quote-based pricing and multi-year contract billing. Go-to-market is sales-led, with technical design engineers working directly with customer engineering teams through a 'Request a Solution' workflow. Revenue mechanics depend on custom component orders across varying production volumes, with additional higher-value integration captured in finished assemblies. SES has expanded through three acquisitions since 2021 (Frost Magnetics, Wirebenders, Magnetic Technology) while leveraging sister-company resources including direct access to Magnetics core materials and shared engineering infrastructure with Spang Power Electronics.
