Inspection technology for foreign body detection
The inspection technology for foreign body detection is a technique that makes it possible to search for foreign bodies in various foods, but also in other products such as plastics , wood or textiles, which should not be present in the actual product.
Application in the food industry
Most often this technology is used in the food industry. Before the packaged products leave the manufacturing plant, they are technically x-rayed to ensure that there are no foreign bodies such as metals, glass fragments, plastic parts or bone fragments in the product. These objects, some of which are life-threatening and unsavory for humans, are referred to as foreign bodies in quality assurance.
The following technologies are mostly used today, depending on the application, for checking foreign objects:
- Magnets
- Industrial metal detectors
- X-ray inspection systems
- Sorting systems
The following institutions, founded by retail companies among others, regulate foreign body detection in industrial food production:
etc.
Application in the automotive supply industry
In the automotive supplier industry, electronic connectors are also searched for in the connectors during the manufacture of vehicles. These are usually metallic foreign bodies that remain in the connector during the injection molding of the connector, caused by a tool break . As a result, there is a risk that a plug contact will not function properly during further processing and the vehicle will fail due to a technical defect. Damage to the company's image and expensive product recalls are the result. Here, too, the technology of metal detectors and X-ray systems is used.
