ZHF-006 Automatic Ultrasonic Tube Filling and Sealing Machine

The ZHF-006 automatic ultrasonic tube filling and sealing machine brings tube positioning, filling, sealing, coding, trimming, and finished-tube output into one compact rotary system.

After a tube is placed in its matched holder, the indexed process controls each subsequent operation. The machine is intended for compatible plastic and aluminum-plastic laminated tubes used for creams, gels, ointments, pastes, adhesives, and similar products.

Key operating data:

• Production capacity of 20–35 tubes per minute

• Four filling-range options from 6 to 500 mL

• Adjustable sealing diameter from 5 to 50 mm

• Tube height up to 200 mm

• 20 kHz ultrasonic sealing system

• AC 220 V single-phase power supply

Why Use Ultrasonic Sealing?

The ZHF-006 directs 20 kHz ultrasonic vibration to the open end of the tube. Localized friction at the material interface generates the heat needed to fuse compatible thermoplastic sealing layers.

Because the energy is concentrated at the sealing area, the process does not depend on heating the entire tube tail. This shortens preparation time and helps limit unwanted heat exposure on the printed outer surface.

Ultrasonic sealing does not remove the need for correct tube alignment and a controlled filling process. The sealing zone should remain as clean as possible, and production tubes should be tested with the actual formulation before final settings are approved.

Integrated Tube Packaging Process

Eye-Mark Alignment

A photoelectric sensor reads the printed eye mark on the tube. The positioning mechanism then rotates the tube so that the artwork and sealing direction remain aligned from one package to the next.

Controlled Filling

The filling station meters the selected volume into each tube. An anti-drip nozzle helps control trailing and product buildup around the filling area, particularly when working with creams and pastes.

Different filling components are available for the following volume ranges:

• 6–60 mL

• 10–120 mL

• 25–250 mL

• 250–500 mL

The appropriate range should be selected according to the target volume and the flow behavior of the product.

Ultrasonic Sealing

The ultrasonic station applies concentrated vibration to the tube tail, joining the compatible inner sealing layers without adding a separate adhesive. Sealing settings must be matched to the tube material, wall structure, diameter, and required closure finish.

Coding and Trimming

After sealing, the machine can form production information in the tube-tail area and trim excess material to produce a straight, orderly edge. The required date or batch-code format should be defined when the machine is configured.

Finished-Tube Output

Processed tubes leave the rotary work area for collection or transfer to the next packaging stage. This coordinated sequence reduces separate handling between filling and tube-tail finishing operations.

Tube and Product Compatibility

The ZHF-006 is intended for compatible plastic and aluminum-plastic laminated tubes. Its adjustable format range supports multiple packaging sizes, subject to the correct tube holders and machine setup.

Actual compatibility depends on the tube’s sealing layer, wall thickness, dimensions, artwork position, and response to ultrasonic energy. Product viscosity, particles, stringing behavior, and filling temperature should also be reviewed during sample testing.

Technical Specifications

Production speed may vary with the tube format, filling volume, product properties, operating settings, and tube-loading arrangement.

Selecting the Right Configuration

Target Fill Volume

Select a filling range that comfortably covers the required nominal volume. Product density and flow behavior should be considered alongside the stated milliliter range.

Tube Material and Dimensions

Provide the tube material, diameter, overall height, wall structure, cap type, and sealing-layer information. Different tube sizes may require matched holders or other format parts.

Product Characteristics

Viscosity alone does not determine fillability. Density, particles, aeration, temperature sensitivity, stringing, settling, and product recovery between cycles can all affect filling performance.

Seal and Code Requirements

Confirm the required tube-tail shape, finished edge, code content, character arrangement, and artwork orientation. Printed tube samples help establish the correct eye-mark and sealing settings.

Output Requirement

The stated capacity is 20–35 tubes per minute. The practical output should be evaluated against the selected filling volume, product behavior, tube size, coding requirement, and operating method.

Applications Across Industries

Cosmetics and Personal Care

The ZHF-006 can be configured for facial cleansers, hand creams, skincare creams, lotions, gels, toothpaste, and other compatible personal-care formulations packed in squeezable tubes.

Pharmaceutical Products

Compatible topical ointments and gels can be processed when the selected product-contact materials, cleaning procedure, and production controls meet the requirements of the intended application.

Food Products

The machine can be evaluated for compatible food pastes and semi-fluid products. The formulation, hygiene procedure, contact materials, and tube structure should be reviewed before production.

Industrial Products

Adhesives, glues, lubricating pastes, and similar industrial formulations may be suitable when their viscosity, particle content, and chemical properties are compatible with the filling components and tube material.

What to Confirm Before Ordering

Prepare the following information so the machine can be reviewed against the actual packaging task:

• Tube material and sealing-layer structure

• Tube diameter and overall height

• Printed eye-mark position

• Target filling volume

• Product density and viscosity

• Particle or fiber content, if present

• Required production capacity

• Tube-tail shape and trimming requirement

• Batch or date-code format

• Available electrical and factory utilities

• Tube samples and representative product material

Testing with production-grade tubes and the actual formulation is recommended before the final configuration is approved.

ZHF-006 FAQs

How should I select between the four filling ranges?

Choose a range that covers the target volume without placing the normal fill point unnecessarily close to the range limit. Product density, viscosity, and required dosing consistency should also be evaluated before the filling component is selected.

Can one machine process several tube diameters?

The stated sealing diameter is adjustable from 5 to 50 mm. Different diameters or tube shapes may require matched holders and format parts to maintain correct positioning throughout the rotary process.

Will ultrasonic sealing work if product enters the sealing area?

Heavy contamination can affect any tube-sealing process. Filling settings and the anti-drip nozzle should be adjusted to keep the tube tail clean. Tubes should also be tested under realistic production conditions rather than assuming residue will have no effect.

What samples are required for machine testing?

Provide production-grade tubes, caps, representative product material, the target filling volume, eye-mark details, and the required seal and code format. Samples from the intended packaging supplier are preferable to unprinted trial tubes.

Can the machine fill products containing particles or fibers?

Suitability depends on particle size, concentration, settling behavior, and the internal dimensions of the filling path. A product test is required before confirming a configuration for particulate or fibrous formulations.

Why might actual output differ from the rated capacity?
