Gematria Selects Signature Touch Metal Detector from Mettler-Toledo Safeline

Gematria Products is dedicated to creating superior nutritional supplements and antioxidant formulas that improve the health and well-being of customers around the world. To help ensure the quality of their products, they decided to add a metal detector to their existing packaging line to achieve that final product quality check. They approached Mettler-Toledo Safeline, the leader in product inspection, and selected a Signature Touch metal detector.

“We wanted a reliable, high performance metal detector that could handle all of our capsules and liquids in all of our packages. We also needed it to fit into our crowded packaging room on an existing line,” noted Wanda Sanders, QA Manager at Gematria. “I’ve worked in the food and nutritional supplement industries for many years, and I’ve had the best experiences with Safeline metal detectors. I went to the WestPack trade show last year specifically to look at them. Of course, I looked at other metal detectors while I was there.”

The high performance Signature Touch is designed for seamless integration into production lines and exceptional levels of detection sensitivity and stability. It features Safeline’s high frequency advanced detection coil technology and dynamic filtering techniques to identify the most difficult to detect non-magnetic stainless steels and non-spherical fine wire contaminants as well as common ferrous and non-ferrous tramp metal.

“We’ve never had a single customer complaint at Gematria, so the metal detector wasn’t installed to remedy any existing problems. It’s simply a precaution,” explained Sanders. “There is always the potential that metal contamination could come from raw materials or the manufacturing process, so it’s good to check every finished product before it goes out the door. Our Safeline metal detector helps ensure that customers open the bottle and get exactly what the label says, with no surprises. As a line of defense, it limits our exposure.”

This attention to quality has permeated all activities at Gematria since the day it was founded in 1996 by Todd Ovokaitys, M.D., who received his medical training at John Hopkins University. Using specialty raw materials like nucleic acids and amino acids, which are combined with various vitamins and minerals, Gematria’s unique formulations offer a variety of health benefits. Today, the company formulates, manufactures and packages 49 different products.

The Signature Touch metal detector holds up to 100 different product settings in its memory for quick and easy recall during changeovers. Multiple products can be inspected with one setting thanks to Safeline’s “product clustering” capability that allows a wide range of parameters to run simultaneously.

At Gematria, their 49 different products are divided into six groups to maximize detection sensitivity and minimize false rejects. “One of our products in particular, called UltraMins, was tricky because it contains iron, copper and magnesium, which will trigger the metal detector if it’s not set up well. This product has its own setting."

“We test the metal detector’s sensitivity every morning before we bottle, which is typically three times a week. We use test sticks to be sure the metal registers,” said Sanders. “The sensitivity of our metal detector has been perfectly consistent, and we’ve had no false rejects, in part because we’ve had such good support and training to set up our metal detector to handle our challenging products.”

Designed for ease of use, the Signature Touch features a color touchscreen control panel and a single-pass auto set-up routine that allows the metal detector to be programmed to handle a new product quickly and with minimal training. The metal detector is password protected, with varied levels of access permitted, to ensure no unauthorized personnel inadvertently adjust important parameters. At Gematria, production lines operators are given access to change products while the QA Manager can go deeper and adjust the detection settings, if needed.

“We are very happy with our Safeline metal detector. It takes a weight off my shoulders, knowing that any potential metal contamination would be caught before the product goes out the door,” concluded Sanders. “At Gematria, we are committed to formulating and manufacturing the highest quality products. Our metal detector is an important tool in that effort.”
