Ignition coil components
Ignition coil components：The shell and frame of the automobile ignition coil are generally made of PBT and PPO injection. Using low-temperature plasma surface treatment technology can not only completely remove the surface contamination, but also can greatly improve the surface activity of the skeleton and enhance the adhesion of the skeleton and the epoxy resin. In order to avoid air bubbles, the welding strength of the enameled wire and the skeleton contact after winding can be increased to ensure the reliability and service life of the ignition coil.
