When a manufacturer needs to secure labels in the correct position, process multiple material layers, or shorten the operation compared with adhesive bonding and stitching, VietSonic can evaluate actual samples, conduct welding trials, and build a machine configuration suited to the production process.
Even a small weld point can affect line pace, appearance, and rework rates. The machine should therefore be developed around the material, weld location, and actual handling method rather than selected solely by its rated power.
Small labels, flexible parts, and surfaces that shift easily require a suitable welding horn and fixture. Effective positioning helps operators place products more quickly and reduces label misalignment between cycles.
Weldability depends on thermoplastic content, number of layers, thickness, and weld area. Sample trials help determine suitable amplitude, pressure, and weld time before the machine is completed.
The worktable structure, activation method, and operating space should follow the existing process. This provides a basis for reducing unnecessary handling and giving operators convenient access to the weld location.
The generator converts electrical energy into mechanical vibration and transfers it through the welding horn to the contact area. With materials containing compatible thermoplastics, the concentrated energy softens the interface locally. Pressure maintained for the programmed time then forms the bond.
Ultrasonic welding is not effective on every fabric or label. VietSonic needs to evaluate the material, multilayer structure, and appearance requirements before determining the welding horn, fixture, and operating parameters.
The video shows ultrasonic spot welding on different fabrics, garment labels, and tags. The machine is also demonstrated on multiple material layers.
Machine-building capability is demonstrated by turning a specific welding requirement into a configuration that can operate on the factory floor. Each step below reduces the risk of selecting equipment that does not match the actual product sample.
The engineering team records the material, number of layers, weld location, appearance requirements, and desired production pace.
The sample is tested with suitable combinations of pressure, weld time, and amplitude to evaluate the bond point and its effect on the surface.
The welding horn, fixture, operating structure, and activation method are selected according to the trial results and production-line conditions.
Operators receive guidance on machine operation, product changeover, and inspection points so the manufacturer can use and maintain the equipment effectively.
Spot-welding equipment may be considered for processes that require localized bonding, involve limited operating space, or need to avoid adding adhesive and thread at the weld location.

No. Results depend on material composition, layer structure, and weld geometry. Sample testing is required before the configuration can be confirmed.
The video shows the equipment welding multiple layers on the demonstrated sample. The maximum number of layers for a specific product still needs to be tested according to thickness, material, and weld area.
A welding horn can be developed for a suitable geometry within the technical limits of the application. Manufacturers should provide the required dimensions, drawings, or weld-mark samples for evaluation.
Integration depends on the available space, product feeding method, control signals, and line pace. VietSonic needs this information to recommend an appropriate structure.
Tell our engineering team about the material, number of layers, label position, and desired production pace. A sample-based technical discussion helps your company determine whether ultrasonic technology is suitable for the current process.
