What Is a Tube Filler and Sealer and How Does It Work?
A tube filler and sealer is a specialized machine that fills tubes—typically aluminum or plastic—with product and seals them in one continuous operation. The SGF-40RF-M is a fully automatic tube filler and sealer designed for high-volume production of adhesives, cosmetics, and pharmaceuticals.
How a Tube Filler and Sealer Works
The SGF-40RF-M follows a streamlined workflow:
Automatic Tube Feeding: Empty tubes are fed from a magazine into holders on a rotary indexing table.
Orientation: Tubes are positioned correctly for filling and sealing.
Filling: A volumetric metering system dispenses the precise amount of product (50-250ml, customizable).
Sealing: Tube tails are sealed using the machine's sealing mechanism.
Coding (Optional): Batch numbers or dates are printed on the tube.
Ejection: Finished tubes are automatically discharged.
The entire process is pneumatic-controlled, allowing easy adjustment of filling quantity and speed. The machine uses a 16-station design, enabling continuous operation .
