The safety and reliability of the initiating explosive devices (IEDs) are critical for the weapon system. As the core components of IEDs, the method of resistance designing and the performance of conversion energy of energy conversion components (ECCs) are worth being studied. In this paper, the design method for the resistance of ECCs is established based on the finite element discrete method, and the currents of melting and electric explosion are presented for evaluating the performance of ECCs. The results show that the resistance of the ECCs is 1 ± 0.05 Ω with consistency. The ECCs were designed by the established design method of resistance and manufactured by the established machining method. The melting current of ECCs is 1.8 A, which is calculated by the infrared temperature measurement and finite element simulation. The electric explosion current of ECCs is 5 A, which was obtained by combining the snapshot obtained via the high-speed camera and finite element simulation.
