Ultrasonic PP Box Welders / Welding Machines

High-frequency ultrasonic vibrations (usually 20–40 kHz) are applied to the material. Vibrations cause the material 's molecules to heat up at the joint interface due to friction. The material melts and fuses together without additional adhesives or fillers. Pressure is maintained while the material cools, forming a strong bond. Key Features of PP Ultrasonic Welding Machines Designed specifically for thermoplastics like polypropylene. The ultrasonic horn (sonotrode) is tailored to the specific shape and size of the PP box. Adjustable frequency and amplitude: Pressure and timing controls for consistent welds. Options for manual, semi-automatic, or fully automated welding systems. Low energy consumption: Compared to other welding methods.
