Custom processing of valve parts for plants, large castings, and brass.

In the plant industry, the reliability and durability of valves are essential for the safe operation of the entire plant. Valves used in high-temperature and high-pressure environments require careful material selection and precise machining. Inappropriate materials or processing can lead to leaks or damage, potentially resulting in plant shutdowns or accidents. Our products have extensive processing experience with not only iron, aluminum, and stainless steel but also special materials such as castings and brass. We own large turning centers with a maximum diameter of φ1,600 and five-axis machining centers, enabling us to handle the complex shapes unique to castings and achieve high-precision finishes for brass components all in-house. [Usage Scenarios] - Updating valve components in plant equipment - Replacing aging valve components - Manufacturing valve components from special materials (castings, brass) [Benefits of Implementation] - Shortened procurement lead times - Reduced management workload - Stable supply of high-quality valve components
