Single-Filar Coil Winding
EBD Coil winding technology is developed specifically to wind micro coils for minimally invasive medical devices. Our coil winders can wind coils down to .001″ diameter wire on a .010″ mandrel using our innovative closed-loop filar tension control system. The machine flexibility enables the filar tension to be recipe controlled from 5 grams to 600 grams during the entire wind.
The picture above reflects this technology from our modular multi-filar systems. Each multi-filar platform can produce catheter coils using one, all, or somewhere in between the filar heads, you define for your machine.
The above picture shows a coil on the tip of Lincoln’s nose, on a penny, alongside a human hair at the right. Coils length and filar count are only limited by your facility floor space.
- Winds stacked (tight pitch) or loose (variable or fixed pitch) coils on a spinning mandrel.
- Right chuck position can be adjusted to get variable mandrel lengths.
- Mandrel length is part of the recipe setting and travel is limited accordingly.
- Up to 250 process recipes can be stored and shared between the two wind heads.
- Recipe edit menu allows up to 30 repeating combinations of any pitch, angle, direction, speed, tension and length.
- Recipe steps can ramp pitch between set points (plus angle ramp with vision option).
- Displays of parameter set points and actual values.
- Records of mean & 2xSTD deviation of all measured variables on each wind.
- Filament slack control that maintains tension at all wind speeds.
- Brushless servo drives on traverse and both ends of mandrel (no back shaft).
- Alphanumeric color touchscreen display for program entry and status displays.
- Acrylic enclosure panels with light curtain to isolate each winder operation.
- Ethernet communication for remote monitoring & program update capability.
- Color monitor display of B/W vision-based angle measurement (vision option only).
