Why this company matters

Shanghai Advanced Inspection Technology provides X-ray inspection systems and components for non-destructive testing of 3D printed parts. The company differentiates through vertical integration from X-ray tube manufacturing to complete inspection systems, supported by proprietary high-frequency X-ray generator technology. This integration allows for higher resolution imaging compared to general-purpose inspection alternatives, which is critical for detecting defects in additively manufactured components.

The company's core technology includes X-ray tubes, portable and industrial generators, real-time imaging systems, and CT tubes. These products serve quality control in additive manufacturing, aerospace, defense, automotive, industrial casting, medical devices, pressure vessels, and oil pipelines. The company claims 85% of sales are exports to Europe, the US, Japan, and Brazil, and positions itself as a global market leader in security X-ray tubes.

Shanghai Advanced Inspection Technology has partnerships with Oak Ridge National Laboratory and Idaho National Laboratory for additive manufacturing nuclear component inspection. The company was founded in 2001, acquired the US DUNLEE factory (now Chronos Imaging) in 2018, completed approximately $276 million in B-round financing in 2024, and began IPO counseling with Guins Securities in 2025. Key investors include Guoshou Equity, Beijing Advanced Manufacturing Fund, Shenzhen Capital, Light Cloud Fund, and Zhongxin Capital.

Competitors include YXLON International, North Star Imaging, and VJ Technologies. The company's vertical integration and proprietary X-ray generator technology provide a cost advantage and higher resolution imaging for AM-specific defect detection. However, the broader industrial X-ray inspection market is mature, and the company must continue to demonstrate that its AM-focused solutions deliver measurable quality improvements over general-purpose systems.
