Ignition coil

        With the development of the automobile industry, its performance requirements are higher and higher. The ignition coil can improve the power, the most obvious effect is to increase the torque at medium and low speed when driving; eliminate carbon deposition, better protect the engine and prolong the life of the engine; reduce or eliminate the resonance of the engine; fully burn the fuel and reduce emissions. To make the ignition coil fully play its role, its quality, reliability, service life and other requirements must comply with the standards. However, there are still many problems in the current production process of ignition coil: after the epoxy resin is poured outside the framework of the ignition coil, a large amount of volatile oil is contained on the surface of the framework before the mold is taken out, which leads to the weak adhesion between the framework and the epoxy resin, and the finished product can not make the ignition coil work well In use when the temperature rises at the moment of ignition, bubbles will be produced in the tiny gap of the joint surface, which will damage the ignition coil and even cause an explosion. After plasma treatment of the ignition coil framework, it can not only remove the nonvolatile oil pollution on the surface but also greatly improve the surface activity of the framework. That just says it can improve the bonding strength between the framework and epoxy resin, avoid the generation of bubbles, and improve the welding strength between the enameled wire and the skeleton contact after winding. In this way, the performance of the ignition coil in the production process has been significantly improved, and the reliability and service life has been improved.
