Tube Sealing Machine Selection Guide & Product Overview

I. What is a Tube Sealing Machine?

A tube sealing machine is a packaging equipment designed to seal the tail, emboss batch numbers, and trim the edges of tubes (plastic tubes, composite tubes, aluminum-plastic tubes) after they are filled with liquid, paste, or viscous materials.

  • Working Principle:
    1. Ultrasonic / Hot Air Principle (For Plastic/Composite Tubes): Melts the inner wall of the tube mouth via high-frequency vibration friction or hot air, which is then pressed and fused together by mechanical jaws.
    2. Pneumatic Folding Principle (For Aluminum-Plastic Tubes): Mechanically folds and crimps the tail of the aluminum-plastic tube multiple times (such as 3-fold or 5-fold) to achieve a tight physical seal.
  • Core Value: Ensures products are leak-proof and oxidation-free, delivers smooth and aesthetic seals, prints clear batch numbers, and significantly enhances the premium look of the finished product.
  • Applicable Industries: Cosmetics (toothpaste, facial cleanser), pharmaceuticals (ointments, gels), food (jam, chocolate sauce), adhesives, and fine chemical industries.

III. Frequently Asked Questions (FAQ)

  1. Q: What is the fundamental difference between the Aluminum-Plastic Tube Sealing Machine (TS-80) and Plastic Tube Sealing Machines? A: * Hot Air / Thermal Conduction Type (e.g., Plastic Tube Machines): Relies on external heating (usually hot air or heating blocks) to bake the inner wall of the tube mouth directly, softening the plastic before pressing it shut.
  2. Ultrasonic Type (QDFW-125): Relies on high-frequency vibration to generate friction heat. It uses an ultrasonic horn to make the plastic molecules at the tube mouth collide violently, generating heat internally to fuse the tube.

  3. Q: What are the advantages of the Ultrasonic Tube Sealing Machine (QDFW-125)?

  4. A: Ultrasonic sealing is a "cold sealing" method. It does not generate continuous high temperatures at the seal, making it friendlier to heat-sensitive materials (such as certain biological gels and high-end skincare products). Furthermore, the sealed and trimmed edges are neat and beautiful, without damaging the printing on the tube body.

  5. Q: Can the machine automatically print batch numbers or production dates?

  6. A: Yes. All of our models are equipped with a date character matrix/font library. While sealing the tail, the character molds leave a clear embossed steel stamp on the tube tail via mechanical pressure, which will never fade.

  7. Q: How is the filling accuracy guaranteed? (For FW-006 / HZNF-60B)

  8. A: We utilize a high-precision piston pump volumetric filling system, controlling the error within ≤±1%. By adjusting the piston stroke, users can easily adapt the machine to different filling volumes.

IV. Customization Capabilities

As a professional manufacturer, we support deep customization based on your specific requirements:

  1. Mold Customization:
  2. Precision-customized tube holders (Cups) based on sample tube dimensions provided by the customer to ensure the sealing is perfectly vertical and aligned.
  3. Support for irregular/special-shaped sealing customization (e.g., curved tail seal, hang-hole seal, wavy/serrated seal).
  4. Functional Upgrades:
  5. Automatic Tube Loading System: Optional automatic tube hopper feeding system for fully automatic models to further minimize manual labor.
  6. Temperature-Controlled Hopper: For high-viscosity or easily solidified materials (such as Vaseline, wax pastes), we offer hoppers with mixing/agitation and electrical heating functions.
  7. Electrical & Environment Adaptation:
  8. Voltage Customization: Voltage and frequency can be customized (110V/220V/380V and 50/60Hz) according to the destination country's regulations.
  9. Multi-Language Interface: The PLC control interface supports multiple language options, including Chinese, English, Spanish, etc.
