Custom PVC Film Ultrasonic Welding Machine for Production Requirements
VietSonic designs the machine system, welding horn, and fixture based on each company’s material, weld dimensions, target output, and actual inspection standards.

Your business needs more than a machine that simply generates ultrasonic waves
In PVC film production, the key question is not whether the machine can operate, but whether it can consistently create a reliable weld on the correct material and along the required product geometry.
A system is only truly suitable when the welding horn, fixture, pressing force, vibration amplitude, and welding time are precisely coordinated. This is why VietSonic approaches every project from the actual product sample instead of selecting a machine based only on nominal power.
Inconsistent weld seams
The weld may be misaligned, partially bonded, or inconsistent along the seam profile.
Difficult to control sealing performance
The product may leak at certain points even when the exterior appears to be bonded.
Dependence on manual operation
Quality and cycle time may vary depending on the operator.
Difficult to scale production
The current method may no longer meet demand when order volumes increase.

Ultrasonic energy is concentrated at the contact area between the horn and the material, creating a bonded seam that follows the profile engineered into the horn surface.

VietSonic develops the solution from the actual product sample—not by guesswork
Each project is developed around the actual material, weld geometry, and operating requirements of the business.
Sample assessment
We evaluate the PVC film type, thickness, number of layers, surface coating, geometry, and required welding position.
Process testing
We assess weldability and identify the appropriate operating parameter range for the material.
Machine and fixture design
We design the welding horn, positioning fixture, press stroke, and operating method for the product.
Trial run and commissioning
We run sample trials, fine-tune the parameters, train operators, and hand over the operating process.
The machine is engineered as a complete production station
Welding performance depends on more than the ultrasonic generator. VietSonic integrates the mechanical system, welding horn, fixture, and process parameters to match each specific product.
The welding horn and weld seam must be developed as one integrated solution
The horn surface profile determines the energy transfer area, while the fixture maintains positioning and pressure throughout the cycle.
The machine should be evaluated by product results—not only by equipment specifications
Before production begins, the company should clearly define the inspection criteria so that VietSonic can design and conduct trials against the correct target.
The seam is correctly positioned, continuous, uniform, and visually acceptable.
The two material layers remain securely bonded and do not separate easily at the welded area.
Water-tightness or air-tightness is verified according to the company’s specified test method.
Wrinkling, burning, shrinkage, and damage outside the weld area are minimized.
Loading, welding, and unloading times support the required productivity.
The result remains consistent across repeated operating cycles.
Suitable for a wide range of products requiring bonded seams on PVC film
Suitability should be confirmed using an actual sample, especially for multilayer films, coated materials, or products with strict sealing requirements.
Technical bags and packaging
Creates weld seams on film products that require bonding along a defined profile.
Waterproof products
Suitable for parts where seam continuity and sealing performance must be controlled.
Flexible tubes and pouches
Welds film layers along straight lines, curves, or custom-designed profiles.
PVC film accessories
Bonds flexible components without adding adhesive to the weld area.
Advertising products
Processes film components that require clean seams and a consistent appearance.
Custom applications
Develops custom welding stations around the company’s sample, dimensions, and production process.
From product challenge to a production-ready machine system
The company works directly with our engineering team throughout sample testing, design, and solution refinement.
We evaluate the technology directly on the company’s own material.
We develop the horn according to the required length, profile, and bonding geometry.
The fixture precisely positions the product and supports more consistent operation.
The system can be built as a standalone machine or integrated into an automated process.
Parameters are fine-tuned based on weld results and acceptance criteria.
We transfer operating procedures, setup instructions, and key considerations when changing products.
Local support makes technical consultation, inspection, and troubleshooting more convenient.
We are not limited to standard off-the-shelf machines when the product requires a custom structure.
What your business should know before investing
Can the same parameter set be used for every type of PVC film?
No. Thickness, flexibility, additives, number of layers, coatings, and weld geometry can all affect the result. VietSonic must test the actual sample before determining the final configuration.
Does ultrasonic welding require adhesive?
The bond is created by mechanical vibration and pressure at the weld area, so no additional adhesive is required.
Can the weld seam be designed in a custom shape?
Yes. The horn can be designed for a straight seam, a defined weld area, or a custom profile, subject to an evaluation of horn size and amplitude distribution.
Can the machine be integrated into an automated production line?
Yes. Depending on the process, the system can be developed as a standalone station, a semi-automatic machine, or a signal-integrated unit within an existing production line.
What information should a company provide for VietSonic to recommend a solution?
The company should provide a material sample, drawings or weld dimensions, target output, material-loading method, and post-weld inspection criteria.
