Metal cans have traditionally proven to be more challenging to inspect than lower-density containers, as the packaging itself absorbs more x-ray beams. The toughest challenge when inspecting metal cans is to detect small physical contaminants that are located on the base or near the side walls of the can, especially if they have side ribbing. Ring-pulls can also affect sensitivity. In addition to the can itself, the production environment and manufacturing requirements create further inspection challenges including: Simultaneously checking for fill levels and contamination detection Effectively rejecting cans without denting them Removing consecutive non-conforming products Ensuring accurate removal of faulty products even at high speeds METTER TOLEDO Safeline X-ray offer a range of metal can inspection solutions to ensure all physical contaminants are detected whilst simultaneously conducting quality control checks, guaranteeing canned food safety.
