How they fulfill customer needs
THE BUSINESS NEED:
A leading snack foods manufacturer, belonging to a division of a large global consumer packaged goods (CPG) company, recently approached Hardy regarding their checkweighing needs. Existing product inspection systems were not meeting their operational expectations. The Customer’s Project Engineer told Hardy that they were “challenged by not being able to repeatedly meet their speed/accuracy checkweighing specifications of better than 250 milligrams resolution, at 400 milliseconds per pack”. In addition, their existing systems: • required expensive “green board” custom hardware • had proprietary software • and maintenance was expensive and unreliable
THE OPPORTUNITY:
“They wanted to find and implement an alternative solution. They felt they had an opportunity to reduce manufacturing costs by minimizing product giveaway, if they could just meet their check weighing specifications consistently, “ explains Area Business Manager, Stan Modzel. At the same time they wanted to install checkweighers that would:
THE SOLUTION:
Hardy’s Engineering Manager, Dean Raby presented the Customer with the solution: “We offered them multiple HI4050CW check weighing bundles. This solution met all their needs.” The check weighing bundle consists of a digital, ceramic load cell and check weighing controller:
THE SUCCESS:
Operational Results The customers operational and engineering teams ran an off-line trial which produced promising results. A decision was made to install 12 x HI4050CW bundles onto one of their production lines. Dean Raby, Hardy’s Engineering Manager monitored and verified the results by doing random checkweighs manually over a period of more than 4 weeks.
“All 12 product inspections systems were monitored and upstream filling systems adjusted. The mean difference and standard deviation measured improved over the 4 week period. No safety issues were experienced,” Dean confirms. The baseline on the previous systems was delivering = 0.54g, with a standard deviation = 0.82.
The final analysis with the new Hardy HI4050CW bundles delivered a weight variance mean of = 0.11g with a standard deviation = 0.20. The results were better than the 0.25g specification they were trying to attain.
No production line stoppages occurred during the test phase and no issues were found with secondary weight checks.
Financial Savings
“The customer calculated that the reduction in finished product giveaway would deliver savings of up to 1 Million dollars per month per manufacturing facility. This was based on installing 160 checkweighing bundles on 14 manufacturing lines in their packaging area, and running 3 shifts,” Area Business Manager Stan Modzel explains.
