Amway has installed eight checkweighers and six X-ray systems on canister, stick-pack and pouch packaging lines at its Nutrilite manufacturing plant in Ada, Michigan, US.
Mettler-Toledo's product inspection group has supplied the equipment.
Mettler-Toledo's Hi-Speed checkweighers and Safeline X-ray will inspect canisters and bulk stick-packs on six packaging lines, as well as cartons of stick-packs and pouches, depending on the line, Healthcare Packaging reports.
The PowerChek X-ray system provides high levels of sensitivity to maintain product safety, while the XE3 checkweigher has superior accuracy by using electromagnetic force restoration weigh cells rather than strain-gauge load cells.
This system is capable of rejecting over and under-weight packages.
Amway Nutrition Manufacturing technician Josh Soyka said: "Our stick-packs and pouches are made of foil, so X-ray inspection after packaging on every one of our lines helps ensure final product quality.
"The X-ray systems and checkweighers are the easiest machines on our line to change over. Four taps on the touchscreen and the new product is selected. If the package size also changes, we can adjust the guide-rails in less than one minute."
Amway has previously used two Mettler-Toledo Hi-Speed XE2 checkweighers and one Safeline SideChek X-ray system on its canister packaging line.
Amway Quality Assurance engineer Brooke Ondersma said: "The success of that first Safeline X-ray system drove the decision to buy five more."
