The machine is uniquely designed to cap glass bottles and caps of varying sizes, facilitating adjustments easily without the need for changing parts. One of its key features is the “No Bottle – No Cap system,” which is augmented by its compact design, efficient operation, low noise levels, energy efficiency, straightforward operation, easy adjustments, and simplicity in maintenance and cleaning. This high level of automation ensures a smooth production process.

Operationally, the Automatic Twist-off Cap Vacuum Lug Capping machine works by reducing the air pressure inside the bottle using a rapid steam injection method, ensuring the cap is tightly secured. It then creates a vacuum by applying cold water over the bottle. Additionally, the machine is fitted with a unique vibrator feeder for Lug caps, and offers an optional waterfall-type Cap feeder elevator, enhancing its versatility and efficiency in cap handling and application.
