Yogurt containers blown neck to neck
Wimm Bill Dann, a major Russian dairy producer adds capacity by making its yogurt bottles neck-to-neck on a reciprocating blow molding machine.
When Russian Dairy Wimm Bill Dann was looking to add capacity, they turned to Uniloy, which had just introduced its Neck-to-Neck (N2N) UR Series reciprocating blow molding machines. This innovative machine produces two containers oriented neck-to-neck per cavity in a single cycle. The result is high output, with reduced energy usage and cycle times, compared to comparable blow molding machines. The first two Model UR90-16-N2N machine systems were delivered to Wimm Bill Dann in 2009 to produce 100-mL HDPE liquid yogurt containers. Each machine could produce over 20,000 of the 6.5-g containers per hour. Uniloy also spearheaded the container and mold design to help optimize the container from a previous weight of 9 g. This 30% reduction yielded three key benefits: cost per container came down, cycle time to produce containers was reduced, and sustainability goals were met.Learn about packaging innovation at The Packaging Conference in Orlando, February 3-5, 2014“We’re very happy with the machines, which our staff find easy to operate and maintain,” says L. Danilushkin, chief engineer at Wimm Bill Dann. “We average over 98% efficiency on these machines and find weight variations are less than 5%. In fact, we’re so satisfied, we’ve purchased another two lines.” The new systems, delivered in March 2012, will add capacity in the 100-mL container and also produce a 200-mL size.
