How Many Steps from Winding to Finished Ignition Coils? Full-Process Production & Kit Supply Revealed

This video presents the complete production flow of Ignition Coils, showcasing three key stages: 1.Winding & Core Assembly High-permeability silicon steel laminations are stacked, and pure copper enameled wire is precision-wound by fully automatic winding machines for primary and secondary coils, with turns and tension controlled by closed-loop servo systems for optimal electromagnetic efficiency. After winding, core and coil assemblies are vacuum-dried to remove moisture. 2.Potting & Assembly Assemblies are loaded into PBT/PA66 heat-resistant housings, with vacuum epoxy potting eliminating internal air voids to enhance insulation and heat dissipation. After potting curing, high-voltage output terminals and carbon rods/diodes are assembled to suppress back EMF. Fully automatic assembly lines complete housing sealing, laser marking, and appearance inspection. We maintain large quantities In Stock covering thousands of vehicle models.
