QFW Semi Automatic Ultrasonic Automatic Plastic Tube Sealing Machine for Cream Tube Sealing Cutting Machine

A semi-automatic machine that uses ultrasonic technology and pneumatic drive to seal and trim plastic tubes (cream, cosmetic, pharmaceutical and similar products), combining PLC control with manual loading/unloading for reliable, precise tube-end sealing and cutting.

The machine uses high-frequency ultrasonic vibrations to generate localized heat at the tube end, softening and fusing thermoplastic material while simultaneously trimming the excess to produce a clean, sealed edge—without adhesives or bulk external heating.

It is designed for thermoplastic tubes commonly used for creams and gels (for example PE, PP, PVC and other thermoplastics). Compatibility can vary by formulation and laminate; we recommend sample testing for multi-layer or specialty laminates.

Minimum hose/tube diameter: 13 mm; maximum hose/tube diameter: 50 mm. Sealing width is 50 mm. For other shapes/dimensions consult the supplier for possible tooling or configuration.

Semi-automatic means operators manually load and unload tubes and the machine performs the sealing/cutting cycle automatically once initiated. PLC controls and pneumatic actuation automate the sealing parameters and cycle execution.

Standard voltage offering is 220 V (customizable to other mains voltages on request). The specification lists a rated power of 2.0 kW and typical listed power consumption of 500 W; ask the supplier for exact electrical requirements and wiring details for your configuration.

The machine is pneumatic-driven for actuator motion and uses a PLC as its core control component to manage cycle timing, ultrasonic parameters and safety interlocks.

Dimensions are 1100 × 800 × 1150 mm (L × W × H). It's compact for bench or line-side mounting but verify clearance for operator access and tube loading when planning integration.

The product listing indicates free spare parts are provided (confirm which parts and quantities with the supplier). Typical wearable parts include the ultrasonic horn/sonotrode, booster, tooling/anvil and cutting edges. Routine maintenance includes keeping tooling clean and checking pneumatic and electrical connections.

Installation and training policies vary by supplier. Many vendors offer installation support and operator training either included or as an add-on—confirm these services and any associated costs before purchase.

Standard safety elements include PLC-controlled cycle interlocks, emergency stop, guarded ultrasonic tooling area and pneumatic control. Users should follow local machine-safety regulations and use appropriate PPE when operating or servicing the machine.

Yes. Voltage options are customizable and tooling can often be adapted for specific tube shapes, diameters or sealing widths. Contact the supplier with product samples and production requirements to discuss custom tooling or configuration.

Throughput depends on tube size, operator speed and selected cycle parameters. Because this machine is semi-automatic, production rate is also influenced by manual loading/unloading. Ask the supplier for example throughput figures or arrange a sample run to determine realistic rates for your product.

Common causes include incorrect ultrasonic amplitude or time settings, worn or misaligned horn/anvil, inadequate tube placement, or incorrect pneumatic pressure. Check and clean tooling, verify PLC parameter settings, ensure proper tube positioning, and consult supplier support for diagnostic guidance.

Warranty terms and after-sales service vary by manufacturer/distributor. The listing mentions free spare parts; for warranty period, response times, preventive maintenance contracts and parts replacement policies, confirm directly with the seller before purchase.
