In aluminum die casting and other metal casting processes, internal voids known as shrinkage cavities, gas porosity, or blowholes typically occur. These defects are hidden beneath the surface and cannot be detected through visual inspection. Therefore, X-ray inspection systems are essential for identifying the location and size of these voids to ensure product quality and prevent failure.

Aluminum die-cast parts often feature complex geometries. With standard 2D X-ray images taken from a single angle, it can be difficult to distinguish actual defects from overlapping structures. Furthermore, inspecting dense metallic materials or large samples requires an X-ray source with high tube voltage and penetration power.

Our horizontal X-ray inspection systems feature a 360-degree rotating turntable stage. This allows operators to observe the workpiece from multiple angles simply by placing the sample on the stage. For more detailed analysis, the Computed Tomography (CT) function generates 3D and cross-sectional images. This enables the observation of internal structures without destructive testing (cutting or grinding) and allows for dimensional measurement and comparison with CAD designs using Stereolithography (STL) data.

The μRay8700 horizontal X-ray inspection system is equipped with a high-power 130 kV microfocus X-ray tube and a high-resolution 6-megapixel Flat Panel Detector (FPD). This combination delivers wide-field, high-definition imaging optimized for detecting shrinkage cavities in aluminum castings.
