How do industrial metal detectors for packaging work?

Our industrial metal detectors for packaging and packaging lines work on a balanced-coil system that allows for accurate inspection and rejection of metal contamination in packaged products.

When products pass through the aperture, the magnetic field created by the coils will allow metal contaminants to become detectable.

Should any be identified, the system will efficiently remove them from the packaging production line with a variety of possible rejection devices – such as a robotic arm, photogated air blast, or lift-flap.

A signal upon contaminant detection can trigger an audible alarm or visible beacon to make you aware that contamination has been found. You can also choose to stop the line on detection or continue the product flow as normal after rejection of the contaminated product.

What types of metal might be found in packaged food and pharma applications?

Many instances can lead to certain metal contaminants entering your packaged applications, such as:

  • Raw materials – including buckshot, barbed wire, and fishhooks
  • Tool wear and tear – including broken blades and sieve wire
  • Maintenance practices – including washers and bolts
  • Personal effects – including jewelry, paper clips, and other objects

Therefore, you should consider an industrial metal detector for packaging applications to minimize the risk of these metal contaminants accidentally entering and affecting your products when they reach the market.

What factors can impact sensitivity when you inspect packaged applications?

Many things can affect the sensitivity of your industrial metal detector for packaging, including:

  • The size of the metal detection system aperture
  • The orientation and position of the metal contaminant
  • The type of metal contaminant inside the packaged products
  • The type of packaging material used, such as metalized film
  • The operating frequency of the detector
  • The conditions of your factory, including temperature, vibration, and airborne electrical interference

Explore our range of industrial metal detectors for packaging applications and learn the features and characteristics of each to help find the right system to enhance your metal detection in food packaging or pharmaceutical packaging lines.
