Tips for Metal Detection Testing

Metal detector test standards are the measuring stick that companies in the food manufacturing and packaging industry use to maintain safe and effective metal detection systems.  Since the presence of even a single contaminant in a batch of products could cost a company millions of dollars, not to mention the confidence of their customers, it is essential that companies do everything in their power to ensure the safety of their products.   

Using a metal detector is the most foolproof way of staying on top of product integrity, as the detector will immediately indicate the presence of any type of contaminant.  Of course that safety process is only as good as the detector itself and that’s why test standards should be used to ensure the proper function of all detectors. Using metal detector test samples is a quick and easy way to determine whether your equipment is functioning properly and keeping your products free of contamination.

At Regal Packaging, we produce metal detector test standards in a variety of shapes and sizes in order to accommodate different types of detectors.  We have everything from spheres and rods to cards, each engraved with its own unique certification number. Our products are made in ferrous (chrome steel), non-ferrous (brass) or stainless steel 316.  We also offer aluminum, soda lime glass and ceramic (ZR02).

In order to ensure product safety, it is suggested that you use three different types of metal detector test samples, since tuning drift might make it easier to detect one type of metal rather than another.  The greater the variety of metals you use, the more thorough the testing and the more confident you can be in the end results. This way you’ll know that as each item is scanned and a foreign substance is found, the entire product would not be rejected and nothing with contaminant ends up on store shelves.

When using metal detector test standards it is suggested that you position them so that they will pass through the center of the detector tunnel as this is the least sensitive position inside any metal detector.  If a test piece can be detected in this position, then it is likely to also be detected as it passes through the more sensitive side areas of the tunnel. This way you can be sure that your detector is operating accurately at every point.  

The use of stainless steel 316 in metal detector test samples is particularly important as it has non-magnetic properties that make it particularly difficult to detect, making it the industry standard.  If your detector can accurately pick up test pieces made of stainless steel 316 then it should easily be able to do the same for other types of metal that are easier to detect. If you’re using SS 304 or some other grade stainless steel, you may be missing other types.

At the same time, our test pieces are designed not to degrade, making them easily able to withstand constant use and maintain certification standards.  This is a particularly attractive quality, as detectors should ideally be tested as frequently as once an hour in order to maintain a high level of safety, and a good auditor will want to know the proper certifications are met.

That’s why Regal Packaging Services, Inc. goes to such great lengths to provide top quality metal detector test standards.  We understand the importance of keeping your equipment functioning optimally, which is why each piece we produce is manufactured with care and certified for life.  

We also understand that machinery can differ and each company may have its own specific needs, so we’ll work with you to make the exact pieces you require.  Whether you need a 24ft “rope” or a 1/2” x 3/16” “pill,” we can design and manufacture it to meet your challenge.

The safety of your products and your customers is too valuable to take lightly, so when you’re looking for metal detector test pieces you can rely on, make sure you go to the industry leader, Regal Packaging Services, Inc. That way you’ll know you’re getting the very best.
