Plastic Children's Toy Ultrasonic High-Frequency Welding Machine

Ultrasonic High-Frequency Welding Machine for Plastic Children's Toys

The principle of the ultrasonic high-frequency welding machine for plastic children's toys involves generating a high-pressure, high-frequency signal of 20KHz (or 15KHz) from a generator. This signal is converted into high-frequency mechanical vibrations through a transducer system and applied to the plastic children's toy workpieces. The friction between the surfaces and molecules of the workpieces raises the temperature at the interface. When the temperature reaches the melting point of the plastic children's toy material, the interface rapidly melts, filling any gaps between the parts. Once the vibrations cease, the workpieces cool and solidify under a certain pressure, completing the welding process.

Advantages of Ultrasonic High-Frequency Welding for Plastic Children's Toys

Speed — Welding time ranges from 0.01 to 9.99 seconds per cycle.

Strength — Capable of withstanding high tension and pressure.

Quality — Leak-proof (water and air).

Economy — No screws or adhesives required. Reduces labor and lowers costs.
