924 Multi-Filar Coil Winding Machine

The multi-filar coil winder machine uses a camera vision system to wind fine filaments around a spinning mandrel and produce multi-filar micro coils with up-to 4 filars. After the coils are produced, they are used for medical and electronic products, including neurovascular and cardiovascular catheters and electrodes for diagnostic and interventional procedures. Our coil winders are capable of different tensions on each filar enabling our customers to produce micro, multi-filars coils with accuracy and speed.

Coils with multi-filars have different tension, torsion, and stiffness properties. The ability to weave together different material filaments also allows for interesting electrical properties. This makes multifilar coils very popular to use for guiding catheters. The versatility of this machine makes the possibilities endless!

The precise control of all process variables is increasingly important as the material gets smaller. Programmable wind tensions of less than 1 gram and wind angles of less than 1 degree require the use of control systems not previously associated with coil winding. The unique use of machine vision to measure wind angle without touching the filament, and state-of-the-art control systems, make this our most precise machine on the market. The adjustable tailstock allows use of variable-length mandrels.
