924 Coil Winder: Multi Filar
The Engineering By Design 924 Multi-Filament Coil Winder machine uses a vision system to wind fine filaments around a spinning mandrel and produce multi-filar micro coils with up to 4 filaments. EBD coil winders deliver exacting control of all winding parameters, with programmable filament tension that achieves tight precision down to extremely low values.
Wind filaments as small as .001 inch diameter wire using our innovative closed-loop filar tension control system.
The coil in the second image was formed by winding 12 individual wires, each .0045 inch in diameter, over a .035 inch diameter spinning mandrel.
