Ultrasonic Welding Generator https://www.bjultrasonic.com/shop/ultrasonic-welding-generator/ is used by a variety of quality products, for example, thermoplastic welding machine, spot welding, parts of metal and plastic between the mosaic machines, ultrasonic machine, ultrasonic grinder and ultrasonic plastic processor. The ultrasonic welding process uses high frequency mechanical sound waves (ultrasonics) to create molecular heat between thermoplastic materials. These high frequency acoustic vibrations are transmitted through thermoplastic material by a sonotrode. Typically two parts are located and supported in a fixture beneath the sonotrode. The sonotrode extends and applies a clamping force (pneumatic) to the parts. Localized frictional heat is generated at the joint area (energy directors) creating a molecular bond between the two parts. Typical operating frequencies are: 20 kHz, 30 kHz and 35 kHz.
