High-Speed, High-Precision Packaging Automation for Modern Production Lines The Vertical Continuous Bag-Making and Filling Machine from Unionscience is an integrated packaging automation solution that combines weighing, bag forming, filling, sealing, and cutting in one continuous process. Designed for high-throughput manufacturing, it offers superior accuracy, efficiency, and reliability in packaging applications for food, chemical, and pharmaceutical industries .
At the system core, the Unionscience MC512 CPU and S2 bus servo drives communicate via EtherCAT and EtherNet/IP , delivering real-time, synchronized control of all motion elements — including film pulling, feeding, deviation correction, sealing, and cutting. This ensures every bag is made with consistent precision and speed.
Key Advantages High precision: Achieves ±1mm bag length accuracy, minimizing slippage and film deviation.
High speed: Produces up to 60 bags per minute , ideal for continuous packaging lines.
Simplified control: Compact architecture and easy parameter setup shorten commissioning time.
Cost-effective performance: Reduced hardware complexity while improving production efficiency.
