To create high-quality products, powder technology is an essential foundational technology. Since our establishment in 1968, we have consistently strived to acquire high-level powder technology. In particular, our contract processing division has become our mainstay, having cultivated extensive experience and achievements. We have responded to a wide range of customer requests, handling the processing of many materials and refining various processing techniques such as crushing, classification, mixing, drying, coating, and compounding. The fine powder products developed using the processing technologies gained from our extensive contract processing experience are our original offerings. These products utilize our unique chemical grinding technology, enabling us to achieve a level of grinding that cannot be obtained through other grinding methods, as well as allowing for special processing such as compounding with inorganic materials, compounding between resins, and surface coating.
