The AX-3000CT-D/H is a dual-source micro-nano industrial CT system, belonging to large-scale high-precision multi-purpose industrial CT machines. It is equipped with a large walk-in shielded lead room, which is suitable for scanning operations of some strip-shaped workpieces and provides radiation shielding protection in compliance with national standards. The machine is equipped with a double-column type high-precision mechanical operation platform, which has a high magnification ratio. Combined with various radiation sources (dual radiation sources can be configured) and detector combinations, it ensures a wider scanning penetration range and higher system resolution of the equipment, thereby meeting higher detection quality requirements. It can be widely used in injection molding and casting, electronics and electrical appliances, archaeological research, aerospace, military industry, new materials, advanced manufacturing, new energy, earth resources and life science research and other fields.
