Quality Checking Packaged Products

摘要

Metal detectors and x-ray machines both have a place on the production line. When used together, they're a formidable force. This article will explain how they work and why different packaging types and products can affect their performance. With a metal detector, metals that have one or both conductive magnetic characteristics, such as brass, bronze, ferrous metals, etc., will create a detectable signal. Non-magnetic stainless steel is harder to pick up; it's a bad conductor and certain food products with added iron, moisture, salt, and acids, tend to mask metal detection. Known as the 'product effect,' this can impact inspection performance.
