Abstract
Systems and methods for forming insulation on magnet wire are provided. An extruder that includes one or more rotating screws may receive a thermoset polymeric material and process the thermoset polymeric material to increase its pressure and temperature. An extrusion crosshead assembly in fluid communication with the extruder may receive the thermoset polymeric material and press extrude the thermoset polymeric material as insulation onto a magnet wire. A curing device may then cure the extruded insulation material.
Claims20
A method for forming insulation on a winding wire, the method comprising:
- providing, to an extruder comprising one or more rotating screws, a thermoset polymeric material containing less than thirty percent by weight of solvent;
- processing the thermoset polymeric material within the extruder to increase its temperature and pressure;
- press extruding the thermoset polymeric material as insulation on a magnet wire;
- and
- curing the extruded insulation material.
A method for forming insulation on a winding wire, the method comprising:
- providing, to an extruder comprising one or more rotating screws, a thermoset polymeric material containing less than thirty percent by weight of solvent;
- processing the thermoset polymeric material within the extruder to increase its temperature and pressure;
- press extruding the thermoset polymeric material as insulation on a magnet wire;
- and
- processing the magnet wire with a curing device that cures and further removes solvent from the extruded thermoset polymeric material.
A system for forming insulation on magnet wire, the system comprising:
- an extruder comprising one or more rotating screws, wherein the extruder is adapted to receive a thermoset polymeric material containing less than thirty percent solvent by weight and process the thermoset polymeric material to increase its pressure and temperature;
- an extrusion crosshead assembly in fluid communication with the extruder and adapted to press extrude the thermoset polymeric material as insulation onto a magnet wire;
- and
- a curing device adapted to cure the extruded insulation material and further remove solvent from the extruded insulation material.
