High-speed letter weighing system
Streamline your mail processing with an ultra-fast weighing system that accurately handles high-speed sorting, ensuring precision and efficiency in your operations.

Weighs and Sorts Postal Items Rapidly
The HC-VLS from Wipotec is a high-speed letter scale designed specifically for mail, logistics, and postal services that need precise and efficient weighing and sorting of postal items. It utilizes an innovative vertical transport system with three synchronized conveyor belts, allowing letters to stand freely during measurement, ensuring accuracy down to 0.5 grams. Operationally adept, it can handle up to 60,000 items per hour, making it ideal for high-speed, continuous processing of letters, direct mail flyers, and other postal items. The HC-VLS stands out with its wear-free EMFR weigh cell, ensuring long-term reliability without maintenance interruptions. Integrated Active Vibration Compensation (AVC) enables accurate weighing even in non-vibration-free environments. Easily integrated into existing lines as a single or multi-lane system, the HC-VLS provides unmatched scalability and operational efficiency, crucial for high-volume processing environments.
