15kHz 4200W High-Power Ultrasonic Welding Machine

Synergistic effect of core components (performance support for high-end models)

1. The ultrasonic generator , acting as the "power center" of the equipment, converts mains power into high-frequency alternating current, providing continuous and stable energy support for vibration. The deluxe model features an intelligent generator that supports multi-mode precise control, provides real-time feedback on power changes to avoid energy waste, and adapts to the welding needs of different workpieces.
2. The core "electromechanical energy " conversion component of the transducer uses a high-performance piezoelectric ceramic wafer, which can convert the high-frequency AC power output from the generator into longitudinal mechanical vibration waves of the same frequency. The deluxe model's transducer has higher vibration efficiency and stronger stability, ensuring no performance degradation during long-term operation.
3. The precision amplitude modulator performs the function of "amplitude amplification and matching," adjusting the transducer's vibration amplitude to the optimal range based on the workpiece material and thickness. Constructed from high-strength, wear-resistant materials, it accurately transmits vibration energy, reduces losses, and ensures uniform welding.
4. The customized welding head (mold) is a key component that comes into direct contact with the plastic workpiece. Its shape is perfectly adapted to the welding surface of the workpiece, and it can evenly transmit the vibration waves transmitted by the amplitude modulator to the welding area while applying preset pressure to ensure that the energy is concentrated on the target area. The deluxe model supports customization of welding heads of various specifications to meet diverse workpiece processing needs.

II. Complete Molecular-Level Welding Process

1. The workpiece positioning and pressure application process precisely places two plastic workpieces to be welded onto the tooling fixture. After the equipment is started, the welding head descends and applies constant pressure to the workpieces, making the welding surfaces of the two workpieces fit tightly together, laying the foundation for subsequent welding.
2. The high-frequency vibration and friction-generated heat welding head vibrates longitudinally at high frequency and high speed, causing the molecules on the welding surface of the workpiece to vibrate synchronously and violently. The friction between molecules generates instantaneous high temperature, which causes the plastic on the welding surface to melt rapidly and form a uniform molten layer.
3. preset effect, the generator stops outputting energy, and the vibration immediately ceases. The welding head maintains its original pressure, allowing the molten plastic molecules to fully diffuse and fuse under pressure, ensuring a tight bond.
4. and cooling, the molten plastic rapidly solidifies, and the molecules of the two workpieces intertwine to form a stable bond. Subsequently, the welding head rises, the tooling fixture releases, and a complete welding process is completed. The final weld strength is comparable to that of the plastic raw material itself, with excellent sealing performance.

III. Core Advantages and Supporting Principles of Luxury Models

• Precise welding : The intelligent generator works in conjunction with the high-performance transducer to ensure stable vibration frequency and controllable energy, avoiding over-melting or poor welding, and ensuring product consistency;
• High efficiency and environmental protection : The heat generated by molecular friction only acts on the welding surface, the heat-affected zone is small, and there are no consumables, no waste gas or waste residue generated, which meets the green production standards;
• Stable and durable : The heavy-duty integrated frame and wear-resistant core component design reduce vibration during equipment operation and ensure welding accuracy and equipment life under long-term high-load production.
