Starting with actual tube samples, our engineering team designs the ultrasonic sealing assembly, fixtures, pneumatic system, electrical cabinet, and control program to build a sealing station that fits the customer’s packaging process.
A factory needs more than an ultrasonic generator. The machine must position each tube correctly, apply stable pressure, allow process settings to be configured, and repeat the sealing cycle consistently. The engineering solution must therefore begin with the tube, its packaging material, and the actual operating method.
The tube-tail width, plastic layer structure, and required seal pattern directly affect the tooling design. Actual samples allow our engineers to determine the contact surface and suitable test parameters.
The PLC controls the operating sequence, while the HMI allows operators to monitor machine status and configure authorized parameters. This supports standardized operation across production shifts.
The frame, operator position, electrical cabinet, and maintenance access must be arranged for the available factory space. If the machine needs to be integrated into a production line, our engineers will assess the control signals and mechanical interfaces.
The actual video documents the process from the 3D model to the completed machine. It allows manufacturers to evaluate our ability to integrate mechanical systems, ultrasonic technology, and control components into a single machine.
We record the tube dimensions, material, sealing area, and required seal pattern.
We create the machine model and arrange the sealing assembly, tube-holding mechanism, frame, and operator position.
We install the electrical cabinet, PLC, HMI, sensors, and control components according to the operating sequence.
We adjust the tooling and process parameters, then inspect the seal appearance on both sides of the tube.
The configuration shown in the video was developed for sealing the tail ends of lubricant tubes. The tooling holds the tube in the working position, the pneumatic mechanism applies pressure, and the ultrasonic system transfers energy to the contact area for the configured duration.
The control interface is positioned on the front of the machine cabinet. Operators can start the system, monitor its status, and access the parameters configured for the sealing cycle.
When the tooling presses the two material layers together, high-frequency mechanical vibration is transferred to the contact area. Concentrated energy softens the material locally, while pressure is maintained briefly to stabilize the seal. The process requires no additional adhesive, but the final result must still be validated on the customer’s actual tube structure.
The positioning mechanism keeps the tube tail within the tooling’s contact area.
The ultrasonic assembly generates vibration and concentrates energy along the designed seal line.
Pressure is maintained during the cycle so the bonded area can stabilize before the tube is removed.
The machine follows a short operating sequence that allows technical personnel to observe each step and assess how the equipment can be introduced into the existing packaging process.
The operator places the tube tail in the designated position.
The control signal activates the holding mechanism and sealing assembly in sequence.
Ultrasonic energy is transferred while the configured clamping pressure is applied.
Check seal continuity, the embossed pattern, and uniformity on both sides of the tube.
To shorten the assessment process, please prepare the following information:
VietSonic will use this information to propose the machine configuration, manufacturing scope, and sample-testing plan.
Sealability cannot be determined from the material name alone. It depends on the layer structure, additives, thickness, and sealing-area geometry. Testing actual samples is the most reliable assessment method.
Tooling changes or fixture adjustments may be possible when the size range remains within the machine’s design limits. Our engineers need to know all planned tube formats in advance to develop the changeover method.
An integration solution can be developed after assessing the tube-feeding method, control signals, cycle time, and available installation space.
