A packaging line earns the label “high-speed” when weighing, filling, sealing, and conveying run as one continuous process instead of a sequence of manual handoffs. For a plant moving from a few hundred packs an hour to 500 or 600, the difference is not a faster conveyor belt. It is a shift in how the whole line is controlled.
From a Single Scale to a Continuous Line
Ecronic’s path to automated packaging started with a single component, not a full line. The DCS-50 electronic weighing scale, introduced in 2004, replaced manual scales with something a plant floor could trust for repeat accuracy. Five years later, the high-speed dual-scale DCS-50FB1 pushed that accuracy to higher speeds and earned seven patents along the way.
The first fully automated packaging line followed in 2010, built as a working prototype rather than a product on a shelf. It combined bag feeding, weighing, filling, and sealing into a single controlled sequence, the same architecture that Ecronic’s automatic lines still use today. In 2012, COFCO Group became the first major customer to run that line in production, and by 2015 an automated rice packaging line built for Yihai Kerry was processing 1,000 tons a day.
