VietSonic developed the VS1532 to join the inner and outer layers of insulated cups. The equipment is engineered around the product structure, material, and actual operating requirements of each business.
Welding quality depends directly on the geometry of the contact area, the construction of each layer, whether the material is suitable for ultrasonic welding, and how the parts are positioned during the cycle. Therefore, a standard machine configuration may not deliver suitable results for every cup design.
The support fixture and sonotrode must match the joining area so that pressure is distributed consistently.
Welding parameters must be tested and adjusted for the actual material layers rather than based solely on reference settings.
The interface, fixture, and cycle must suit shop-floor operation and the business’s production targets.
The machine is intended for businesses that need to standardize the joining of two cup layers and control the process with a clearly defined machine cycle.
The fixture holds the product in the correct position while the sonotrode is engaged, allowing the operator to load and remove each product consistently.
The machine allows the technical team to set and adjust operating parameters according to test results obtained from actual samples.
Ultrasonic vibration generates localized heat at the contact area of compatible materials, allowing the layers to be joined without added adhesive or direct external heat.
The video documents the progression from the 3D design to the actual machine, control interface, two-layer cup loading, ultrasonic welding, and finished-product inspection. This provides direct evidence for businesses assessing the company’s equipment development capabilities.
The technical team examines the construction, required joining area, and material characteristics before confirming a solution.
The machine structure, support fixture, and sonotrode are designed around the product geometry and intended operating procedure.
VietSonic assembles the equipment, conducts trial runs, and adjusts the parameters based on sample results.
The business can evaluate the finished product, machine operation, and technical requirements before putting the equipment into use.
This 1-minute 45-second video shows the complete process, from machine design to post-weld product inspection.
Key timestamps: 00:00 machine design · 00:30 actual machine and control panel · 00:57 loading the two cup layers · 01:12 ultrasonic welding · 01:27 finished-product inspection.
The three frames below were taken from the VS1532 video to illustrate the points businesses should review when evaluating the equipment.
The ultrasonic system converts electrical energy into mechanical vibrations at an ultrasonic frequency. The vibrations are transmitted through the sonotrode to the contact area between the two material layers. Under suitable pressure, internal friction generates localized heat to form the joint after the hold stage.
Heating is concentrated in the required joining area, without adhesive or direct external heat being applied to the entire product.
The configuration below is the equipment shown in the video. The final configuration may be reviewed according to the product sample and the business’s requirements.
