E-Plan takes pride in having deep knowledge in the design and manufacturing of ion exchange membrane electrolyzers. The ion exchange membrane electrolyzer unit refers to the ion exchange membrane, gaskets, electrolyzer frame, inlet and outlet headers, inlet and outlet hoses, and the press used to assemble them. In the case of salt electrolysis, a unit with a size of 1200×2400 and a current density of 40A/dm², equipped with approximately 90 frames using hydraulic presses, is equivalent to a production capacity of 10,000 tons/Y of NaOH. In this case, the material for the anode side of the electrolyzer frame is made of titanium, which requires skill in welding and bending, while the material for the cathode side is selected based on the concentration of caustic soda, using pure nickel. Recently, these technologies have also been applied to sulfuric acid electrolyzers and are widely used in high-purity refining equipment related to semiconductors. [Technical Features] - Low electrolysis voltage and low power consumption - The anode and cathode chambers can be reliably joined by explosive bonding, ensuring good conductivity - Minimal welding joints, resulting in no leakage - Ability to perform stress analysis due to heat and pressure *For more details, please contact us.

Our company is currently engaged in the design and construction of hydrogen production equipment using renewable energy. As part of future energy measures, electricity will be sourced from renewable energy (such as solar, wind, and geothermal power) to extract pure hydrogen. The intended use is directed towards the development of fuel cells for hydrogen vehicles. Hydrogen vehicles have been on sale since 2015. The exhaust gas is water vapor, resulting in a perfectly pollution-free vehicle. Although significant development costs are incurred in the initial stages, it is a technology with great potential for the future. *For more details, please contact us.*

Explosive bonding is a processing method that involves colliding two types of metals at high speed using explosive force to join them together. It is commonly referred to as "explosive bonding." After ignition, the explosive generates a significant pressure that bonds the metals at the atomic level. The bonding surface becomes wavy, which increases the contact area and results in a very strong bond. One of the advantages of explosive bonding is its ability to join various types of metals. Unlike welding, explosive bonding adheres materials together without heating them, preventing any thermal changes in the materials. This method is particularly effective for bonding metals with significantly different physical properties. With explosive bonding, it is possible to join metals that cannot be joined by conventional welding methods very securely. It is suitable for cases such as titanium and iron or copper and aluminum. Prototyping for research and development can also be conducted. Multi-layer bonding of materials such as stainless steel, nickel, titanium, and aluminum is possible. Rolling after explosive bonding is also feasible. *For more details, please contact us.*
