Ultrasonic molds are used in conjunction with ultrasonic welding machines. The purpose is to weld products such as plastics and metals. Different welding objects require different tool heads. Whether it is near-field welding or transmission welding, only half-wavelength tool heads can make the welding end surface reach The amplitude.

1. The design of ultrasonic mould is not reasonable enough and the production is not precise enough. When the frequency is adjusted, the frequency is not reached, so the ultrasonic energy is not completely released during use, and most of the retained energy is in the ultrasonic mold, which causes the ultrasonic mold to become hot.

2. After the mold is used for a long time, the welding will be weak and the mold will heat up. Continuous heating will easily lead to cracks in the mold. To solve this problem, you must choose a relatively ultrasonic welding machine manufacturer and replace the regular ultrasonic mold.
