Our company specializes in the machining of copper alloys. Copper alloys are metals that possess excellent thermal and electrical conductivity, as well as resistance to rust. Leveraging these characteristics, we have been involved in various fields of copper alloy components, primarily focusing on valve parts and water-related components for residential equipment. We accommodate a wide range of tolerances from 0.05 mm, with lot sizes ranging from 1 to tens of thousands of pieces. Furthermore, by conducting "100% visual inspections," we ensure stable precision and quality. Additionally, our self-developed production management system allows for efficient inventory management, enabling us to supply products with short lead times and at low costs. Utilizing the technical skills and know-how we have cultivated through our specialization in copper alloy processing, we propose our unique ideas to meet our customers' needs. 【Features and Strengths】 ■ Expertise and know-how developed through specialized copper alloy processing ■ Wide range of lot sizes from 1 to tens of thousands of pieces ■ Thorough inventory management through our self-developed production management system ■ Stable precision and quality through "100% visual inspections" *For more details, please download the PDF or contact us.
