We exhibited at the Nepcon Japan 2020 trade show.

Visualize quality control! Adopted by many major mobile manufacturers! No master work required & waterproof testing possible without getting wet with the leak tester *Demo available.

The "WPC6315P002/A/WO" is a waterproof testing device for electronic devices that employs a distortion detection method. Unlike conventional differential pressure methods, there is no need to prepare a master workpiece, and tests can be conducted without wetting the workpiece. The maximum measurement pressure is 20 kPa (equivalent to a water depth of 2 meters). It excels in pressure resolution under low pressure and is effective for airtight waterproof testing of waterproof mobile devices and multi-chamber structural components. 【Features】 ■ Can measure two smartphone-type devices simultaneously ■ Standard accommodates up to A4 size, with custom options available for larger sizes like large televisions ■ Equipped with two circuits of distortion sensors within the capsule ■ Settings can be made in 1 kPa steps ■ Compatible with various model shapes *For more details, please refer to the documentation. Feel free to contact us with any inquiries. *Custom orders and modifications are also accepted.

Supports pressure equivalent to a water depth of 95m! Four-channel smartwatch low-pressure and high-pressure waterproof testing device. Custom orders and modifications are also accepted.

The "WPC6540P10/A" is a low-pressure and high-pressure waterproof testing device for smartwatches, equipped with four circuits of strain sensors inside the capsule. By utilizing three different measurement modes, it enables high-precision leak detection for both low and high pressures. In low-pressure mode, it can be set in 1 kPa steps, allowing for stable leak detection even for workpieces that are easily deformed by pressure. Measurement can be performed simply by changing the bracket to match the shape of the workpiece, contributing to reduced running costs. 【Features】 ■ Four circuits of strain sensors inside the capsule ■ Capable of measuring smartwatches with bands ■ Maximum measurement pressure of 950 kPa (equivalent to a water depth of 95m) ■ Stable leak detection even for workpieces that are easily deformed by pressure ■ Detectable even with different shapes if inspection conditions are the same ■ Minimal running costs *For more details, please refer to the PDF document or feel free to contact us.

Inspect the leakage points of the work using the bubbles that emerge! A compact waterproof testing device for analysis. Custom orders and modifications are also accepted.

The "HPT8701P01" is a waterproof testing device for analysis that lowers an air-pressurized workpiece into water and inspects for leaks and other issues through the bubbles that emerge. By directly submerging the workpiece and applying air pressure, it is also possible to test for leaks at depths of up to 10 meters. This product allows for the insertion of an air-pressurized workpiece into water, and when the air inside the container is exhausted, bubbles will emerge from any leaking workpiece, indicating the presence of a leak. 【Features】 ■ Pressure: Max 0.1 MPa ■ Compact size ■ Capable of testing for leaks at depths of up to 10 meters ■ Containers can be designed to match workpiece size and test pressure *For more details, please refer to the catalog or feel free to contact us.

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 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 a detailed technical explanation is needed, please contact us.

SPACECOOL Inc., which researches, develops, and sells the radiation cooling material "SPACECOOL" that releases heat into space to achieve zero-energy cooling, will exhibit at the "Jumbo Surprise Exhibition," a comprehensive trade fair for electrical materials and housing equipment, held at Tokyo Big Sight from April 17 (Friday) to April 18 (Saturday), 2026, and at Intex Osaka from April 24 (Friday) to April 25 (Saturday), 2026. This material is a new technology that enables zero-energy cooling by converting heat into infrared radiation and releasing it into space, without using any external power. By implementing it in outdoor air conditioning units and outdoor electrical equipment, it helps suppress internal temperature rises, contributing to stable operation of devices and reduction of air conditioning energy consumption, and is being recognized as a new carbon-neutral technology. Its energy-saving performance has been acknowledged, and this material received the 2025 Energy Conservation Award. When you visit the venue, please stop by our booth. Our booth number is 972 (common for both Tokyo and Osaka). We will continue to work towards expanding the social implementation of SPACECOOL to contribute to the stable operation of outdoor equipment and air conditioning units, as well as to reduce air conditioning energy consumption and CO2 emissions.
