VietSonic ultrasonic welding machine continuously welding aluminum-laminated composite film

Actual operation: continuous welding of aluminum-laminated composite film at VietSonic.

Companies need to address the specific requirements of their material

Aluminum-laminated composite films vary in layer structure, thickness, and sealant layer. Companies should therefore evaluate the machine directly with the material they use instead of selecting equipment based only on its rated power.

The weld must run continuously

For long bag edges or film sheets, the roller-welding mechanism moves the material through the ultrasonic zone to form a weld in one continuous process.

Reduced reliance on thread and needles

The weld is formed by ultrasonic vibration combined with pressure at the contact zone. This process does not use sewing thread or needles that puncture the film.

Sample testing before ordering the machine

Weldability and sealing performance depend on the layer structure, surface, thickness, speed, and pressure. Actual samples provide the basis for selecting the appropriate machine configuration and welding components.

Manufacturing capability demonstrated through a working machine and actual welded samples

The video shows a bench-style machine developed by VietSonic feeding aluminum-laminated film through the continuous welding assembly. After operation, the technician directly inspects the sample edge and surface.

Companies need to evaluate more than whether the machine can generate ultrasonic energy. The material-guiding mechanism, welding roller, ultrasonic horn, contact pressure, and operating speed must work together consistently to form a uniform weld on the specified film.

The video records the material passing through the welding assembly and the sample inspection after welding. It provides companies with a clear view of the machine mechanism before submitting samples for testing.

Technical note: The 20 kHz frequency and 1500 W power rating apply to the machine shown in the video. The configuration supplied to each company must be determined according to the film structure, thickness, weld width, required speed, and product inspection criteria.

VietSonic develops the machine around each company’s production process

The company provides its material and output requirements. The engineering team uses this information to conduct welding trials, select the configuration, and complete the machine for actual operating conditions.

Receive samples and requirements

The company supplies the film, weld dimensions, expected output, and post-weld inspection criteria.

Conduct welding trials on the actual material

The technician adjusts the pressure, speed, and energy level to observe how the weld forms.

Recommend the configuration and welding components

VietSonic determines the ultrasonic system, material-guiding mechanism, and welding roller suitable for the required weld width.

Manufacture, test, and provide operating guidance

The machine is assembled, tested with the agreed sample, and delivered with guidance for the customer’s production process.

Companies receive a configuration supported by trial results

This approach helps engineering and purchasing teams evaluate the machine using the correct material and clearly identify the factors that must be controlled when the machine enters production.

Clear sample-testing data

Companies can inspect the weld profile and agree on the testing method before finalizing the configuration.

A machine designed for production handling

The table structure, material-guiding system, and working area are considered according to the sample dimensions and operator handling requirements.

Local technical support

Companies have a direct point of contact for discussing materials, operating parameters, welding components, and adjustment requirements.

Companies that should submit samples for evaluation

Continuous welding machines can be considered by companies that manufacture packaging or technical products from composite films with a sealant layer compatible with ultrasonic welding.

Moisture-resistant packaging

Products that require aluminum-laminated film edges to be processed and their sealing performance evaluated using the company’s specified test method.

Food and pharmaceutical packaging

Companies with specific materials and standards that require sample welding, compatibility testing, and confirmation of safety requirements before application.

Multilayer technical films

Companies that require a continuous weld and want to integrate an ultrasonic welding assembly into an existing production process.

Send your film sample to VietSonic for evaluation before receiving a configuration proposal

Please provide the material sample, weld dimensions, desired speed or output, and inspection criteria. The engineering team will discuss a welding-trial plan and a machine configuration suited to the actual application.
