35Khz Ultrasonic Spot Welder For Plastic Welding
Altrasonic provide with spot welding machine from 20Khz to 60Khz,it is widely employed to automobile parts and vacuum sealed blister packs in order to get an airtight closure to avoid tampering. Most thermoplastics can be spot welded using ultrasonics.
Principle of Ultrasonic Car Bumper Riveting Spot Welder:
When the ultrasonic role in the thermoplastic plastic contact surface, it will generate tens of thousands of times per second, high frequency vibration, this high-frequency vibration, ultrasonic energy through the ultrasonic wave transmitted to the mold to ultrasonic welding material surface, it will produce high-temperature materials. Plastic contact surface resulting in rapid melting, coupled with stress, it blend and coagulation, so that to achieve the purpose of ultrasonic welding.
