Limitation of measure, shape and material.(ultrasonic welding for PP, PC, ABS, PA, PS, AMMA plastic).
 
Factors in Controlling Ultrasonic Spot Welding
 
Ultrasonic automotive plastics as the condition of ultrasonic welding, the most important is the time to apply welding energy (vibration, welding time) length and pressure, of course, other conditions are also very important. Welding temperature ultrasonic welding material viscosity flow temperature. Otherwise the material will not melt.With the amplitude, the higher the amplitude, the higher the temperature rise. The pressure is applied to the molded article using a cylindrical gaze. General compressed air pressure is 0.1-0.Pa (pressure gauge), sometimes higher. But if the use of high pressure, it will hinder the cylindrical vibration.
 
Principle of Amplifying
They can amplify the amplitude at a particular ratio step by step. For example, the transducer amplitude is 6mm, the booster can amplify it triply to 18mm, and then the horn can make it to 36mm. However, the work life of horn would be shortened with the amplification of amplitude. The required amplitude differs with the welding material.
