Are you facing challenges with inaccurate product weighing, inconsistent bag sealing, or slow packaging speeds for your diverse products? Maintaining efficiency while handling fragile or high-precision materials is a common hurdle.
The EverSmart ES-520A Vertical Form Fill Seal (VFFS) Machine is engineered as the ultimate solution. This advanced system ensures unparalleled weighing accuracy via its 10-head weigher, provides versatile bag forming capabilities, and achieves robust high-speed production. We empower you to overcome packaging hurdles, consistently deliver perfectly sealed bags, and significantly enhance your operational profitability.
The ES-520A VFFS machine integrates cutting-edge automation components to guarantee superior performance, precision, and efficiency across diverse packaging applications.
The accuracy of the dose is determined by the weigher, not just the bagger.
Integrated 10-Head Combination Weigher (ES-10): This multi-head design is the industry standard for ultra-accurate and high-speed weighing of granular, sticky, or irregularly shaped products (e.g., chips, candies, pet kibble). It works by calculating the perfect combination of weights from multiple hoppers, achieving exceptional accuracy of $0.1-1.5\text{g}$ for a $10\text{g}$ to $800\text{g}$ range, drastically minimizing product giveaway.
Program Recovery & Anti-Clog Function: The weigher features a program recovery function that minimizes operational errors and staggered hopper opening to prevent clogging for light or easily blocked products (puffed snacks or crispy rice). (For a technical deep dive into this technology, read:
Gentle Product Handling: The Robust Z-type Bucket Elevator is designed for no collision handling, maintaining the integrity of delicate items like potato chips or dumplings as they are lifted for weighing, ensuring the final product quality is preserved.
The heart of the VFFS precision lies in its motion control, which governs the film pull-down and the sealing jaw mechanics.
Servo Film Conveying System: The ES-520A utilizes a Schneider servo motor for its film conveying system. This ensures exceptionally high positioning accuracy of the film (crucial for printing alignment and consistent bag length), stable operation, and reduced film waste compared to older mechanical or stepper systems.
Intelligent PLC Control System: A reliable Mitsubishi PLC serves as the machine's brain, orchestrating the complex sequence of metering, filling, bag forming, sealing time ($T$), and sealing pressure ($P$). This closed-loop control ensures consistent performance for every bag, whether packaging sugar or pet food.
The machine's former and sealing jaws define its output flexibility. The ES-520A offers unparalleled flexibility in bag making:
It can seamlessly produce standard pillow bags, retail-friendly gusseted bags, functional punch bags, and even 5-12 continuous bag chains for multi-packs. This allows you to rapidly adapt to diverse product presentations and market demands.
The ES-520A is meticulously engineered to address the specific challenges of high-volume, precision packaging:
This machine is built with globally recognized components to ensure reliability, longevity, and superior performance.
Our ES-520A VFFS Machine has consistently delivered outstanding, measurable results for manufacturers worldwide.
Challenge: Increase speed for delicate potato chips by 50% and reduce product breakage.
Solution: Installed the ES-520A with the 10-head combination weigher and Z-type elevator.
Results: Achieved a increase in daily output, packaging 58 bags/minute for 80g chip bags. Product breakage was reduced by 4.8%, and weighing accuracy improved to within ±1g, leading to significant material savings.
Challenge: Required a high-speed, versatile solution for various pet food kibble sizes, demanding stand-up bags for retail appeal.
Solution: Integrated the ES-520A, leveraging its stand-up bag forming capability and the flexible weighing range of the 10-head weigher. (To see how this style compares, view our guide on
Results: Achieved 45 bags/minute for 1.5kg pet food bags, with accuracy consistently within ±1.5g. Energy consumption for the main packing unit decreased by 30.0% compared to the old system.
