Working Process of a Inner Heating Tube Filling Sealing Machine
- Tube Feeding: Empty tubes are automatically arranged and oriented for consistent feeding.
- Positioning & Centering: Tubes are precisely positioned and aligned at the filling station.
- Accurate Filling: A piston pump dispenses a precise and consistent product volume into each tube.
- Tube Tail Folding: The tube tail is folded into a preset shape before sealing.
- Inner Heating Sealing: As the core process, a metal heating head is inserted into the tube tail to apply internal heat.
- Pressing & Sealing: Pressure is applied to fully seal the heated tube tail.
- Cooling & Forming: The sealed area is cooled to ensure strong and stable sealing.
- Coding / Printing: Production date, batch number, or other codes are applied.
- Finished Product Discharge: Completed tubes are discharged and transferred to the next process.
How Tube Filling and Sealing Machines Reduce Product Waste？
Automatic inner heating tube filling sealing machine are designed to maximize efficiency while minimizing material loss. Their precise dosing systems accurately dispense creams, gels, or pastes into each tube, ensuring consistent fill volumes and eliminating overfilling, leakage, or spillage. This level of control not only improves product uniformity but also significantly reduces wasted product during production.
In addition, the automated sealing and tail-trimming process limits material waste at the tube end. Excess plastic is cut cleanly, and a tight, reliable seal is formed every time, preventing product residue and packaging defects. This waste-reduction capability is particularly valuable in cost-sensitive industries such as cosmetics, pharmaceuticals, and food processing, where raw material efficiency directly impacts profitability.
What Maintenance Requirements Do Inner Heating Tube Filling Sealing Machine Have?
- Regular Cleaning: Clean all product-contact parts after each run to prevent contamination.
- Lubrication: Maintain pneumatic and moving components according to manufacturer guidelines.
- Sealing Inspection: Check heating units and cutting parts for wear or residue buildup.
- Calibration: Periodically verify sensors and control system accuracy.
- Preventive Checks: Inspect hoses, seals, and electrical connections to avoid leaks and downtime.
A simple routine maintenance plan ensures stable operation, longer service life, and consistent sealing quality.
