Can ultrasonic welding be used for welding between plastic parts and metal parts? What are the difficulties?

Ultrasonic welding can be used for welding between plastic parts and metal parts.
1. Ultrasonic welding is mainly used for welding between plastic parts and metal parts in the following forms:
Planting welding, rivet welding, and inlay welding.
2. Ultrasonic embedding and welding equipment is suitable for the hot melting and embedding of metal equipment components and plastic equipment components, as well as hardware such as screws and nuts. Ultrasonic embedding welding equipment uses the transmission channel of the welding head and appropriate pressure to instantly squeeze metal parts (such as nuts, screws, etc.) into the reserved plastic holes and fix them at a certain depth. After completion, regardless of tension or torque, they can match the strength of traditional mold forming, which can avoid the disadvantages of damage to the injection mold and slow injection.
3. Ultrasonic embedding welding equipment is widely used for the fusion of digital phase device storage cards, speaker mesh covers, MP3s, computer built-in components, Bluetooth, and fixed copper nuts on hand device shells.
4. The ultrasonic nut embedding and welding equipment has fast production efficiency and quick production conversion. Once the equipment is debugged, it is very fast to switch to production at any time. Just find the product program in the corresponding folder and put it into the corresponding mold to use.
