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 to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

This is an air leak tester for battery cases of electric vehicles (EVs). The battery case has the characteristic of being "large with a significant internal volume, and its structure may deform due to internal pressure." As a result, air leak testing generates "noise caused by its large size and capacity" and "noise caused by expansion or deformation due to internal pressurization." To mitigate this noise, this device features a newly developed smoothing function and a linear fitting correction function used in combination during measurement. Additionally, to achieve low-pressure control that is difficult to manage and to expand flow for large volumes, we provide a bypass box (CBU-600) equipped with an electro-pneumatic regulator for precise pressure control and a pressurization valve with a large effective diameter to supply high flow rates. Measurement methods: Work-Work comparison, Work-Master comparison, Fixed Master comparison Measurement pressure range: 10 kPa, 20 kPa, 50 kPa (depending on specifications) Gauge pressure sensor accuracy: ±2% F.S. Differential pressure sensor accuracy: ±0.5% F.S. Group settings: 0 to 31 groups Power supply voltage / Power consumption: AC100 to 240 V / 100 VA

● What is a hydrogen leak detector? It can measure leaks in small areas that could not be detected in air leak tests and can also identify the leak locations. It is a detector that uses a mixture of 5% hydrogen and 95% nitrogen (non-flammable gas: ISO10156:2017) as the tracer gas. ● What is a helium leak test system? It is a leak test system suitable for high-precision or high-pressure leak inspections. The helium leak test system uses helium gas as the detection gas (tracer gas) and detects the helium that has leaked out. It is the leak test method among Fukuda's leak testers that can detect the smallest leaks.
