The X-ray foreign object detection system automatically identifies contaminants in products, including metallic and non-metallic materials such as glass, ceramics, stones, bones, rigid rubber, and hard plastics. It triggers the backend rejection mechanism to automatically remove defective products from the production line. This equipment is widely used in food, chemical, and pharmaceutical industries for detecting metallic/non-metallic contaminants and defects, with performance unaffected by temperature/humidity fluctuations or salt concentration variations.
