KOUNAN’s Strengths

30 years of proven excellence in the semiconductor manufacturing equipment industry

We are highly experienced in materials and processing that meet SEMI standards. Leveraging our accumulated expertise, we can also provide tailored proposals for your development products.

High-precision composite processing and high production capacity: Surface roughness Ra 0.04μm or less; over 40,000 blocks/flanges per month.

We recognize that producing a single piece versus mass production, or handling a single process versus integrated composite processes, presents challenges of vastly different scales. At KOUNAN, we procure difficult-to-machine and special materials such as SUS316L in large volumes, and perform cutting, welding, and surface treatment in a seamless, integrated flow—delivering defect-free results with excellence.

Development prototypes: over 200 cases per year.

Thanks to our in-house integrated manufacturing, we can deliver prototypes in as little as two weeks and ensure a smooth transition to mass production—providing strong support for your development projects.
