The Ultrasonic Plastic Welding Machine 15kHz 4200W is a heavy-duty industrial welding system designed for precision joining of thermoplastic materials using advanced ultrasonic technology. Operating at a low frequency of 15kHz with a powerful 4200-watt output, this machine is specially engineered for welding large, thick, and high-strength plastic components with excellent bonding quality and durability. It is widely used in industries such as automotive, electronics, medical equipment, packaging, filtration systems, household appliances, and industrial plastic fabrication.
The machine functions by converting electrical energy into high-frequency mechanical vibrations through an ultrasonic transducer and booster assembly. These vibrations create frictional heat at the contact surface of plastic parts, producing strong molecular fusion without the use of adhesives, screws, or additional consumables. The process is clean, fast, energy-efficient, and suitable for high-volume manufacturing applications.
This model is equipped with a digital control system featuring automatic frequency tuning and intelligent overload protection to ensure stable operation and consistent welding performance. Adjustable welding parameters such as welding time, pressure, amplitude, and holding time provide flexibility for different plastic materials and product designs. The welding time generally ranges from 0.01 to 9.99 seconds for improved productivity.
Typical technical specifications include a power supply of 200–240V AC, 50/60Hz operation, pneumatic pressure range between 0.2–0.8 MPa, and heavy-duty steel frame construction. The machine dimensions are approximately 955 × 750 × 1980 mm with a weight ranging from 180 kg to 340 kg depending on configuration. It supports large welding areas up to approximately 250–350 mm and offers deep penetration welding capability for thicker materials.
