吉川工場

The best quality comes from combining experience and technology.

For faster and more precise finishes, we aggressively update our factories with the most innovative and technologically advanced machinery sourced from Japan and around the world. Our range of processing variation is expanding and includes mirror finishes, correction of straightness, and others. We have a wide variety of calibrator and other measurement and quality control instruments and use them liberally. Then we carefully inspect the finished product. Only after an item has surpassed our strict quality control procedures will the finished product be shipped to customers, accompanied with a full inspection report.

When working with temperature-sensitive metals in micrometer unit such as printing roller and injection molding shaft, the temperature and humidity in the factory need to be carefully controlled. At Iijima Kokan facilities, temperature and humidity are maintained at ideal levels. Furthermore, our welding areas are segregated from other areas so that the welding process is not be affected by oil mist from other machinery. Our focused attention on maintaining an ideal work environment helps ensure that only the highest quality products are produced.

In the past in Japan, there was an old saying that "You have to steal skills by seeing your senior's work." At Iijima Kokan, we have never subscribed to such ideas, and we have fostered at atmosphere of sharing skills and knowhow between machinist and technicians so that our quality can continue to be the best in Japan . Iijima Kokan's superior machinery, environment, sharing of knowledge, and worker skills and work experience all contribute to Iijima Kokan's Only 1 Quality.
