Manufacturing method of F-level electromagnetic wire

The invention relates to a manufacturing method of a single-side reinforcement F-level electromagnetic wire, and the manufacturing method provided by the invention is lower in manufacturing cost, is suitable for energy conservation and emission reduction, and can be used for reducing the environmental pollution and ensuring the product performance to be higher. The manufacturing method comprises the following steps: adding a polyester resin into a nano material subjected to surface activation treatment and uniformly stirring to obtain an insulation resin for later use; delivering the insulation resin into an extruder hopper, enabling the insulation resin to be in a high-temperature viscous flow state by virtue of an extruder and continuously extruding the insulation resin from the die sleeve port of the extruder; meanwhile, aligning and preheating a bare copper wire, enabling the aligned and preheated bare copper wire to pass through a forming die of a machine head of the extruder, and packaging the insulatio
