It supports full-process automated production for aluminum tubes, plastic tubes, and laminated tubes, achieving high-precision filling and airtight sealing for various paste and colloid products, becoming the standard production equipment for global tube product manufacturers.
Core Defects of Traditional Tube Packaging Methods
Most small and medium tube product manufacturers rely on manual operation or modified bottle filling equipment for tube packaging, which brings unavoidable quality defects and efficiency bottlenecks, restricting product market competitiveness:
1. Unstable Filling Volume & Uneven Batch Quality
Manual tube filling depends on worker experience and hand pressure, resulting in random filling volume deviation. Modified bottle fillers lack targeted tube positioning and anti-bulging design, easily causing overfilling tube bulging or insufficient filling empty space. Batch products have inconsistent net content, failing international weight inspection standards and leading to customer complaints.
2. Poor Sealing Quality & Easy Leakage
Manual hot pressing sealing produces uneven tube tail pressure, prone to gaps, wrinkles, and incomplete bonding. Paste products with fluidity easily leak from the tube tail during transportation and storage. Low-quality sealing also causes air and bacteria intrusion, leading to product deterioration and shortened shelf life.
3. Residual Air Bubbles Affect Product Texture
Traditional filling methods cannot discharge internal air during tube filling. Trapped air bubbles form hollow gaps inside the tube, causing uneven paste texture, sectional dryness, and layered separation after extrusion, seriously affecting product use experience and brand reputation.
4. Rough Tube Tail Appearance & Low Grade
Manual sealing and cutting have irregular tube tail edges, burrs, and uneven folds. Finished tube products have rough appearance, unable to meet high-end market aesthetic standards and export commodity quality requirements.
5. Low Production Efficiency & High Labor Cost
Manual tube feeding, filling, sealing, and coding require multiple workers for assembly line operation. The production speed is slow with limited output, unable to support large-scale order delivery, and high long-term labor and management costs compress profit margins.
Traditional Passive Optimization Measures & Their Limitations
To improve tube packaging quality, manufacturers often adopt transitional optimization methods, but these measures only alleviate superficial problems without solving fundamental technical defects:
Manual Secondary Trimming & Pressing: Workers reprocess sealed tube tails to remove burrs and folds. It increases labor procedures, cannot eliminate internal air bubbles and volume errors, and has unstable finished product consistency.
Semi-Fixed Volume Auxiliary Tools: Use simple measuring tools to control filling capacity. Tools cannot adapt to different tube specifications, and manual feeding still leads to low efficiency and human errors.
Post-Production Leakage Inspection: Conduct manual sampling inspection for sealed tubes. It cannot screen all defective products completely, leaving hidden quality risks for after-sales leakage problems.
Low-Speed Filling to Reduce Bubbles: Reduce manual filling speed to avoid air mixing. It sacrifices production capacity and cannot achieve complete air removal and uniform filling results.
Working Principle & Core Tube Filling and Sealing Technology
Professional tube filling and sealing machines adopt exclusive automatic tube positioning & correction + vacuum defoaming quantitative filling + ultrasonic seamless sealing + precise edge trimming + intelligent batch coding integrated core technology, completely subverting manual and semi-finished tube packaging modes, realizing one-stop standardized production of high-quality tube products:
The equipment adopts a fully automated rotary tube feeding system. Empty tubes are automatically sorted, positioned, and corrected to ensure uniform tube opening alignment, solving the offset filling problem caused by irregular flexible tube placement. The high-precision servo piston filling system performs fixed-volume quantitative filling according to preset parameters, with filling accuracy controlled within ±0.3ml, completely eliminating batch volume deviation.
Different from traditional bubble-prone filling methods, the machine is equipped with a built-in vacuum defoaming structure. It synchronously discharges internal air during paste filling, ensuring full and dense paste inside the tube without hollow gaps. For different tube materials, it supports dual sealing modes: ultrasonic sealing for plastic and laminated tubes, and hot air sealing for aluminum tubes, realizing seamless and flat tube tail bonding without gaps or wrinkles.
After sealing, the integrated automatic trimming device precisely cuts redundant tube tail edges to form flat and smooth finished tails without burrs. The online coding system synchronizes production date, batch number, and anti-counterfeiting information on the tube tail, completing one-stop production from empty tube feeding to finished product output. All material contact parts adopt food and medical-grade 316L stainless steel, supporting CIP cleaning and meeting GMP hygiene standards for cosmetics, food, and pharmaceuticals.
