Ultrasonic molds are suitable for: plastic welding, electronic communication, toys, stationery, daily necessities, gifts, automotive and other industries.
Vibration node
The welding head and the horn are designed as a half-wavelength resonator with an operating frequency. Under the working condition, the amplitude of the two end faces is the largest and the stress is the smallest, and the amplitude of the node corresponding to the intermediate position is zero and the stress is the largest. The position of the node is generally designed to be a fixed position, but the usual fixed position is designed to have a thickness greater than 3 mm, or the groove is fixed, so the fixed position does not necessarily have a zero amplitude, which causes some sound and part of the energy loss. The sound is usually isolated from other components by a rubber ring or shielded with a sound insulating material. Energy loss is considered when designing the amplitude parameters.
