Air leak tester specifically for airtightness inspection of large battery cases and similar items.

Fukuda Corporation will exhibit at the "2025 YOKOHAMA International Automobile Technology Exhibition"! Please be sure to check out this product at Fukuda's booth! This product is an air leak tester for battery cases of electric vehicles (EVs). The battery case features a structure that is "large with a significant internal volume, and deformation is expected due to internal pressurization." As a result, air leak testing generates noise caused by "the large size and volume" and "expansion or deformation due to internal pressurization." This product is characterized by the use of newly developed smoothing and linear fitting correction functions to reduce this noise during measurement. Additionally, to achieve precise low-pressure control and flow expansion for large volumes, we provide a bypass box (CBU-600) equipped with a pressure regulator that allows for accurate pressure control and a pressure valve with a large effective diameter to supply high flow rates.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is kept to a minimum. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

The low-voltage fuse "SBFC-MS2" is a slow blow fuse that can withstand temporary overcurrents and only blows under continuous overcurrents. It is particularly effective for devices in automobiles where the current temporarily spikes. For example, it protects power window motors, which may blow regular fuses due to the large current that flows temporarily during startup. It is recommended for those facing circuit protection challenges in the automotive and construction machinery industries, as well as for low-voltage fuses (below DC70V).
