Simple motion, precise timing, and thousands of perfectly sealed tubes.
This is a tube sealing mechanism commonly used in large-scale packaging and filling machines for cosmetic, and pharmaceutical tubes.
The sealing unit uses two pivoting lever arms, with each arm controlling an independent sliding press block. Mounted on each slider is a custom-shaped sealing jaw, machined to create the desired sealing profile on the tube.
The system stays normally open using dual tension springs, while a vertically moving cam actuator controls the entire opening and closing cycle. As the cam moves downward, both sliders are driven inward simultaneously, compressing and sealing the tube with synchronized force.
🔑 Key Features:
Cam-driven tube sealing mechanism
Dual lever arms controlling synchronized sliders
Spring-return opening system
Custom sealing jaws for shaped tube ends
Compact and reliable design for high-speed automation
