Advanced Imaging for Precision: 450KV Line Array Industrial CT in Quality Assurance
Industrial CT: Precision Internal Inspection
In mission-critical manufacturing sectors like aerospace, automotive, and medical devices, sub-100 µm internal defects—undetectable by traditional methods—can lead to catastrophic failures. Neway’s YXLON FF85 CT system combines a 450kV/600W X-ray source and Varex 4343 detector array to achieve <3 µm voxel resolution, enabling full 3D reconstruction of aluminum die castings, titanium aerospace brackets, and multi-material assemblies up to 800 mm diameter.
