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.

• 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.

• No need for adhesives, fast processing time.
• Ideal for complex or delicate shapes.
• Excellent weld strength for PP material.
• No consumables or emissions.

• Packaging: Sealing food containers, clamshell packaging.
• Automotive: Joining components like air ducts and reservoirs.
• Medical: Sealing sterile containers and instruments.
• Electronics: Housing assembly for consumer electronics.
