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.

As part of the "Hometown Ibara Future Creation Human Resource Development Project," we welcomed local elementary and middle school students to the special summer program "Ibara Job Exploration Tour 2025," a collaboration between the Ibara City Chamber of Commerce and the Corporate Branding Committee. We conducted a presentation that clearly and enjoyably introduced how our technology supports society, allowing the children to learn about the appeal of manufacturing and the significance of working while interacting with actual devices and products. Through this initiative, we hope to deepen our connection with the community and nurture the curiosity of the children who will carry the future. We sincerely thank everyone who participated, as well as all those involved in planning and organizing the event.
