Abstract: A method of production of an ignition coil which provided with a core so as to form a mold release film which enables reduction of the adhesion with an epoxy resin comprising using a metal to form a rod-shaped center core, dipping the formed center core in a liquid UV curing resin, raising the center core from the liquid and shaking off the excess UV curing resin, irradiating the center core with UV rays to cause the UV curing resin which is deposited on the center core to cure and form an insulating film, attaching a first spool to the outside of the insulating film and winding a secondary coil over it, attaching a second spool to the outside of the secondary coil and winding a primary coil over it, inserting these into a case, then injecting an insulating material into the case to thereby produce an ignition coil.

Abstract translation: 一种制造点火线圈的方法，该点火线圈设置有芯以形成脱模膜，该脱模膜能够降低与使用金属形成棒状中心芯的环氧树脂的粘合力，将形成的中心芯浸入 液态紫外线固化树脂，使液体中心芯从液体中提起并且摇晃多余的UV固化树脂，用紫外线照射中心芯，使沉积在中心芯上的UV固化树脂固化并形成绝缘膜， 将第一线轴连接到绝缘膜的外部并在其上缠绕次级线圈，将第二线圈连接到次级线圈的外部并且在其上缠绕初级线圈，将它们插入壳体中，然后将绝缘材料注入 从而产生点火线圈。
