At our company, we aim for thorough quality control. In addition to installing clean rooms, we stabilize the quality of our products by inspecting them at multiple stages using a wide range of inspection equipment.
In order to respond to increasingly sophisticated demands and diversifying evaluation items, we constantly review the effectiveness of our inspection equipment and actively seek to introduce new equipment.
All employees thoroughly understand that a high-quality, stable production system is essential for earning the trust of our customers.

History management using monitoring devices

Our in-house equipment is equipped with units that monitor process conditions such as processing temperature, voltage, and operating speed. These units continuously monitor process conditions and sample and record data at specified intervals.When an abnormality occurs, the alarm sounds and the details of the malfunction, its value, and the date and time of occurrence are recorded.These sampling data and anomaly histories are transferred wirelessly from the monitoring device to the internal data server and stored there.

Comprehensive development support system with a wide range of inspection and testing equipment

In order to respond to increasingly complex and diverse customer needs, such as the refinement of parts, new materials, and environmental considerations, and to develop products that are always ahead of their time, we have established a “Technology Development Center” at our main factory.
As this is a floor dedicated to technological development, prototyping and experimentation can be carried out on a larger scale and more efficiently.In addition, various analytical devices have been prepared, enabling rapid verification of prototype and experimental results and feedback.In addition, the center also has a plating equipment design and manufacturing department, enabling it to provide development support such as modifying experimental equipment as needed.
