Smooth production scale-up with an experienced global manufacturer.


Spang Engineered Solutions (SES) takes advantage of the supply chain management and global manufacturing of our sister companies, Magnetics and Spang Power Electronics (SPE). With multiple factories, labs, and warehouses in the US and China, we are able to combine the resources of a significant industrial manufacturer with the close attention of a custom producer. The result is that your transition from qualification to production volumes will happen on schedule. No worries about growing pains from your supplier of specialty power chokes.

SES production facilities in the US and China are configured for flexibility and responsiveness, to match the variety in products we make and our customers' expectation for short turnaround. Purchasing, shipping, and warehousing are partially pooled with our sister companies to get economies of scale. Scheduling, QA control plans, and specification control processes use the robust Magnetics system. But our manufacturing schedules and production lines are independent from those of Magnetics and SPE.

Our heritage traces directly back to Spang & Company's beginning as a machine shop making drilling tools for the early oil and gas industry

in 1894. We know manufacturing.
