You define the performance requirements. We design, prototype, and manufacture the component.
Opening
C.A. Spalding provides integrated electrical engineering and manufacturing services for custom magnetic and electromechanical components — from initial design through production. Our engineering team works directly with yours to translate performance specifications into manufacturable designs, eliminating the coordination overhead of managing separate design firms and contract manufacturers.
Customers including Eaton, 3M, and Rockwell have used our concurrent engineering model to bring components to production faster, at lower cost, and with fewer design iterations.
What We Engineer
Our engineering capabilities cover the full range of magnetic and electromechanical components we manufacture, including:
- Power and signal transformers
- Toroidal and bobbin-wound inductors and chokes
- Sensor coils and specialty magnetic assemblies
- Electromechanical assemblies and wire harness integration
If you have a defined performance requirement — voltage, impedance, frequency, form factor, cycle life — we can design to it.
How We Work: Concurrent Collaboration
We embed our engineers into your development process rather than operating as an outside vendor receiving completed drawings. This concurrent model catches design and manufacturability issues early — before prototypes are built and before tooling is committed.
1. Specification review We begin with a thorough review of your performance criteria, application environment, and functional requirements — not just the drawing. Understanding the application allows us to optimize the design for both performance and cost.
2. Initial design and feedback We develop preliminary designs and submit them for your review before committing to prototypes. Early feedback keeps the design direction aligned with your expectations and avoids costly late-stage changes.
3. Prototype production Once the initial design is approved, we produce prototypes for evaluation under your application-specific test conditions — in our facility, using production-intent processes.
4. Test, iterate, finalize We incorporate test results and your feedback iteratively until performance requirements are met and the design is approved for production.
5. Production release The approved design transfers directly into our production environment — no handoff to a separate manufacturer, no requalification, no supply chain gaps.
The Advantage of Integrated Engineering and Manufacturing
When design and manufacturing are separated, cost and manufacturability trade-offs get discovered late — during prototyping or, worse, during production ramp-up. Our quality team works alongside engineering throughout development to verify that designs are both specification-compliant and production-ready before the first production order is placed.
This integration consistently reduces development time, lowers prototype iteration costs, and eliminates the surprises that come from handing a design to a manufacturer who wasn’t involved in creating it.
