What Do Ultrasonic Welders Mean By Pressure Retention, Delay, And Welding Time?
Feb 15, 2022
Ultrasonic pressure holding time is a period of time after the product is welded. Ultrasonic delay time refers to the moment you press the switch, through the delay time before the ultrasonic wave. Ultrasonic welding time refers to the welding time of the moment when the sound head drops and the bottom die contact. For different welding object needs to have a different tool head, the welding when open the pneumatic valve under the timing control, welding head picks up welding end, half the wavelength of longitudinal vibration and the half wave shaped device connected to form a full wavelength plastic welding transducer: drive parts, ultrasonic launch and maintain a certain welding time remove the ultrasonic emission to keep certain pressure back pressure. High power ultrasonic welding machine, composed of a half wavelength transducer. The sequence of the entire control system is.
1. Press the welding object with certain pressure.
2. Hold pressure for a period of time after welding.
