In industries such as cosmetics, personal care, pharmaceuticals, and adhesives, tube packaging is widely used for products like facial cleansers, hand creams, sunscreen, ointments, and glues. Different types of tubes and materials have vastly different requirements for filling, sealing, and cleaning and maintenance. Therefore, when selecting a tube filling and sealing machine, one should not simply compare equipment speed or price quotes, but rather conduct a systematic evaluation based on actual production conditions.

Based on its project experience in integrating hose filling with automated production lines, Baohan Technology has identified the following six key metrics to help manufacturers minimize errors in equipment selection.

I. First, verify the hose material and the sealing method

The end-sealing processes for plastic tubes, composite tubes, and aluminum tubes differ. Plastic and composite tubes typically require heat sealing, end trimming, and batch number marking, while aluminum tubes place greater emphasis on end forming and seal stability. Before selecting a model, you should provide the tube material, diameter, length, end shape, and a sample tube so that the equipment manufacturer can match the appropriate heating, clamping, and end-sealing configurations.

If a single production line needs to accommodate multiple pipe diameters, it is also important to focus on mold changeover time, positioning and adjustment methods, and the ability to save parameter settings to avoid frequent changeovers that could impact efficiency.

II. Designing a Filling System Based on Material Characteristics

Liquids, emulsions, creams, ointments, and adhesives differ in terms of viscosity, flow characteristics, and stringiness. For materials prone to foaming, it is necessary to control the filling speed and the nozzle lift process; for high-viscosity materials, attention must be paid to feed pressure, valve design, and ease of cleaning; and for special materials such as adhesives, additional assessments are required regarding corrosion, curing risks, and sealing materials.

Before finalizing the plan, we recommend conducting test runs using actual product and packaging materials to evaluate filling accuracy, air bubbles, dripping, stringing, and the appearance of the sealed ends.

III. Production Capacity Must Be Aligned with the Rhythm of Upstream and Downstream Operations

The nominal speed of a machine is not the only criterion. Companies should also take into account tube loading methods, filling capacity, end-sealing and cooling time, inspection stations, and cartoning speed to determine the stable production capacity of the entire line. Even if a single machine operates at a very high speed, the efficiency of the entire line will still be limited if manual tube loading or downstream cartoning cannot keep up.

For companies planning to expand production, it is advisable to set aside space in advance for automated tube handling, online inspection, automated cartoning, and data integration interfaces, ensuring that the equipment has room for future upgrades.

IV. Focus on Filling Accuracy and Consistency in Sealing

Filling accuracy directly affects cost control and the yield rate of finished products, while the quality of the seal affects transportation, storage, and the consumer experience. When inspecting equipment, conduct continuous testing using representative products of varying volumes and viscosities, and record weight fluctuations, seal strength, batch number legibility, and visual consistency.

For production lines with high quality requirements, weighing, vision inspection, or hose pressure detection modules can also be configured to automatically reject defective products before they enter the cartoning stage.

V. Replacement, Cleaning, and Maintenance Determine Long-Term Efficiency

Multi-brand, multi-specification production has become commonplace at cosmetics OEM/ODM factories. Factors such as whether equipment is easy to disassemble and clean, whether parts in contact with materials are easy to inspect, and whether parameters can be quickly restored after a product changeover all affect daily production capacity. When selecting equipment, in addition to considering operating speed, it is also important to gain a practical understanding of the processes for disassembly, assembly, cleaning, lubrication, and replacement of wear-and-tear parts.

VI. Incorporate After-Sales Service and Sample Acceptance into Procurement Standards

Tube filling and sealing equipment is classified as a long-term production asset. Companies should clearly define the scope of installation and commissioning, operator training, spare parts supply, and remote technical support, and complete testing of packaging materials and product samples before shipment. By establishing clear acceptance criteria, issues can be resolved in advance during the delivery phase.
