Project Case Studies

Neumann Space engaged us to wind specialised inductors critical to the ignition trigger systems of their propulsion rocket, an essential part of their mission to launch satellites into Earth’s orbit. We collaborated closely with their engineering team to meet all specifications and technical parameters.

The result was a high-quality, precision-wound part delivered on time and to exact standards. The success of this project led to a repeat order and ongoing discussions for further production

L3Harris found themselves without a supplier for a custom transformer used in their power supply units. Coiltek was able to review the specifications, design and produce a working prototype, and deliver an initial batch of 50 units.

We are proud to report that L3Harris has since returned with a repeat order for another 50 units, confirming their satisfaction with both our product quality and service.
