Why Trust Regal Packaging Services?

Why Trust Regal Packagaing ServicesIt would be quite a claim to say that the Testrods Division of Regal Packaging Services provides literally the best metal detection and x-ray inspection verification test pieces on the market.  But we believe it’s not just a claim.  We’re better than our competitors for a number of reasons.  You can trust Regal Packaging Services because:

First, our prices are the best in the market.  You may pay twice as much (or more) for test pieces made by our competitors.  For example, one charges $33.29 for a 1” test ball while ours are just $22.   Another charges $49.  Still another matches our pricing but only provides white balls rather than industry standard colors (red-Fe, green-NFe and blue-SS 316).  Pricing differences like that are true across the board.

Second, our standard of quality is higher.  Many companies use acrylic to manufacture their test pieces.  They’re light and they look nice, but when they break, they shatter.  A broken acrylic test piece on a production line could mean a lot of lost product.  Our test pieces are made from a type of plastic that is nearly indestructible.  We’ve driven over test pieces with a forklift, dropped them from 25 ft and thrown them across our warehouse.  We’ve even heat tested and stressed them to the point of breaking to prove there’s no shattering.  In the vast majority of our testing, you can take the pieces and put them all back together again.  In addition to using certified contaminant types, we use only the highest quality plastics and adhesives in our process.

Third, is our certification – all our test pieces come with a complimentary, traceable certificate that never expires.  There are companies that will tell you the certificates need to be renewed annually, (and expect you to pay for them) when, in fact, the signal produced by the metal inside a test piece never decays or degrades unless it is somehow exposed to the elements.  In addition, at Testrods we can go so far as to provide the NIST sphericity and certification reports if needed.  You won’t get that from anyone else.  And we understand what certification really means.

Fourth, our guarantee and a liberal return policy cover every aspect of our product from manufacturing through sales and delivery.  If you find, for any reason, that you’re dissatisfied with our products, just eturn them for a full refund, no questions asked.  You’re also covered against defects in workmanship of any kind.  And if we miss an item in your shipment or send you the wrong test piece, we’ll make it right as quickly and painlessly as possible.

Fifth, we continue to make it as convenient as possible to order. You can purchase online, over the phone or by email.   We accept credit card, PayPal, ACH, checks and POs as needed.  We understand that getting quality test pieces on your production line is paramount to your success and the safety of your product.  We’re customer-centric and we want to win your long-term business as a customer.

Sixth, we can manufacture any kind of custom test piece you can imagine.  We have the capacity to custom cut material to nearly any shape and size, including mini-cones, ice-cream bars, sugar blocks, pill bottle caps and more.  We love a good challenge, so if your application requires something a little out of the ordinary, give us the chance to meet the need.  You won’t be disappointed.Trust Regal Packaging Services

Finally, and most importantly, our staff at Regal Packaging Services has a combined century of experience in the world of metal detection and x-ray inspection systems.  Have a question about what you can expect from your application and product – just call us.  If one of the guys in our Testrods division can’t answer the question, we can rely on our service and sales team to provide the knowledge-base you need.  You won’t get that from a company selling all kinds of products out of a catalog.  We take pride in being industry leaders.

So there you have it – 7 solid reasons to trust Regal Packaging Services with your need for metal detection and x-ray inspection verification test pieces.

Some applications involve large tubs, vats, or some other type of product travel where it would be nice to have a test piece that floats. Once again, our thermoform cards provide the simplest solution. We simply insert some type of structure that forces the thermoform card to retain air, which, of course, is what makes it float. We have also manufactured floating rods, which are more difficult because there is less space to close in enough air to make the rod float but is doable.

We took an ordinary plastic “chip clip” as defined by the customer and embedded the contaminant into the clip. The clip can be attached to the product on the line without damaging or opening the product for testing purposes.

Bone is a difficult contaminant to find because it can vary widely based on the size, age, and calcium content (as well as feed used) of the animal. After working with several customers, Regal Packaging Services offers Pork, Beef and Chicken Bone Simulate. We have a small range of sizes at a variety of depths to simulate whatever you might expect to find in the product. Our recommendation (assuming your x-ray has visual display) is always to start with a multi-card. Using a multi-card gives you an easy way to test several sizes and depths to determine what matches the bone you’re using. Once you’ve made a comparison, testing the card against the bone you’re looking for, you can purchase a card with a single contaminant for regular testing.

This small pill shaped test piece is used in a system with a vacuum tube that shoots the test piece through the aperture and returns it to the “home” base. Your system may never be like it, but the point is that we can make a customized solution no matter how unusual or impossible it might seem.

As you may have seen in some of the other thermoform card descriptions, we can put nearly as many seeds as you can imagine on a single card. Pictured here you will find a wide variety of configurations and contaminants. Just let us know your specs: size of the card (up to 8” x 8”) along with size and type contaminant(s) and we’ll get you a quote as quickly as possible. Working with a multi-card is especially helpful when you are looking for multiple types of contaminants or when you want to determine what size of the same contaminant you are able to detect. In that event, once the size is chosen, you can order individual card(s) for regular, standard inspection and detection.

There are a wide range of applications that require a test piece much longer than our standard 5” or 6” Testrods. We can make up to 3/8” x 34” or 1/2” x 34” rigid test pieces which can then be extended well beyond that length with a “handle” made of acetal cylinder larger than the 3/8” or 1/2” extension. In the photos, we used a 1” x 24” cylinder handle with a 3/8” x 24” inch extension.

Test pieces can be made in a variety of sizes and given a pointed end in applications that require the contaminant (metal) to be inserted into a food package such as sugar or some other soft packaged food product. This allows the metal to reach the center of the aperture.

Double-End Test Whips are also available, with metal in both ends. One consideration is to make certain that the whip is long enough to keep the metal on the non-testing side of the whip outside the metal free zone of your detector. If you insert, for instance one end of a whip with 2.0mm and 3.0mm Ferrous, you need to make certain that the 2.0mm metal doesn’t affect the detection of the 3.0mm metal (and vice versa). If the 3.0mm metal is inside the metal free zone, then the detector will be reacting to the 2.0 as well as the 3.0 as if they were combined.

Multi-seed laminate test cards are designed for seeds 4.0mm or less. Multi-cards are useful in x-ray inspection to determine what sizes and types of contaminants your system can achieve. They can be especially useful in temperate environments and applications. If your application is rugged or wet, or your standards are larger, we recommend our thermoform multi-cards.

We can simulate a variety of packaging in an application where you need the test piece to mimic what is traveling down the production line. In this case, we manufactured a clear “package” with the seed inside. With this method, the customer is able to reject the container appropriately, and, in the event the package is not rejected, it is easily seen by the line worker for manual removal.

There are two types of “candy bars” pictured here – one similar to a flat candy bar and the other in a custom, near perfect copy of a candy bar. Since we’re now able to produce many variations using colored material, the copy was made in red (Fe), green (NFe) and blue (SS 316). We have the equipment to accomplish nearly anything you can imagine, and these kinds of designs are proof positive.

Need a test piece that looks and handles like chicken nugget? We can do it. Interestingly enough, in this situation, our first version for the customer left too much “void” in the hole where the metal was placed. Given the sensitivity the customer system was using, the void had the effect of causing false positives. We were able to minimize that hole and supply the test piece with almost no void. It’s an example of how we can work with you before, during and after manufacturing to ensure all the specifications were met.

Our standard acetal card is 2 1/4"x3 3/8,” but if needed, we can cut that size down to as small as 1 1/4” x 1 1/4” (with limited engraving). If a larger card or a card with multiple seeds is needed, see our Custom Shape-Size Blocks and Tablets.

This distinctive test piece was created to mimic an actual hamburger patty. The customer supplied photos of the raw product, which we were able to reproduce and then we placed blue glove contaminant. Using this configuration, the customer was able to determine what size piece the vision scanning system could detect with the raw burger as the background. Had they simply used a blank card with the glove, the system could easily have achieved contaminant rejection, but they needed to be sure the system could “see” the blue against the product itself.

A card with 100 seeds in a 10x10 configuration is used to place beneath whole chickens on a production line. This gives the x-ray system operator the ability not just to see IF the equipment can detect the metal in the card, but also WHERE the equipment can detect it. If there is a problem, the operator (or company) can make any changes necessary to achieve the end goal – safe chicken in this case. This card really highlights another valuable facet of our thermoform cards.

In this scenario, a company processing sugar needed to have a “bag” simulated with the same weight in order to accurately fall through the reject mechanism. A lighter test piece had the risk of passing over the reject mechanism.

Our standard cubes are 1” and 1.5,” but we can also manufacture other sizes if needed. The cubes shown here are 1/2" in dimensions. Cubes can be helpful in applications where a ball or cylinder may bounce or roll away during testing, making their retrieval difficult, or, in some cases, present a hazard to the product or production equipment.

This is a test piece that is dropped into a bottle. It’s designed so that the metal appears in the center of the aperture when testing the metal detector. In addition, the round stop makes the test piece easily removable after testing.

Hexagonal Shaped test pieces can be very useful in places where a cylinder or ball might roll or bounce around a production floor whether dropped by a line worker or ejection from a reject mechanism. Hexagons are similar in weight to the 1inch cylinders without having the smooth, rounded cylinder edge.

Our customer in this plant needed a test piece with a thickness less than 5.0mm. Because we have the capacity to customize sizes and shapes, we were able to mill down a product that met their specifications. That’s always our goal, meeting the specs you need for your product, testing environment and contaminants.
