Is The Size Of The Ultrasonic Welding Die Relevant?

The size of the ultrasonic welding machine mold is related, and the ultrasonic mold can be shortened, but we need to know that the grinding height of the ultrasonic mold is within 2mm. Each ultrasonic mold has a fixed frequency. The shorter the ultrasonic mold, the higher the frequency. After exceeding the matching frequency, the device cannot function properly.
Shorten the risk of ultrasonic mold: the welding principle of ultrasonic welding machine is that the frequency of ultrasonic generator transducer ultrasonic mold is similar, forming a vibration loop. If the ultrasonic mold itself shortens, the vibration between the transducer and the ultrasonic mold will be uncoordinated, and energy will be concentrated at the joint between the transducer and the mold, which cannot be released, leading to the burning of the facility.
Therefore, do not modify short wave molds or self-made molds to save costs. If the mold is worn or needs to be changed in shape, it needs to be repaired or remanufactured by a professional mold manufacturer.
Common sense supplement: 15khz ultrasonic mold length: 17-18cm; 20khz ultrasonic mold length: 13cm up and down; 28khz ultrasonic mold length: 10cm up and down; 30khz ultrasonic mold length: 8cm up and down.
