Ultrasonic molds are used in conjunction with ultrasonic welding machines. The purpose is to weld plastic and metal products. 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 Amplitude of.

1. Ultrasonic mold design is not reasonable enough, and the production is not fine enough. The frequency is not reached when the frequency is adjusted, 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 be heated. 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.
