Ultrasonic embedding-ultrasonic welding process

Threaded joints, threaded pins and other metal parts can all be embedded in thermoplastics using ultrasonic waves. According to the size and shape of the metal part, its torsional strength and stability can be achieved. The height difference between the embedding levels allows many welding heads to embed multiple parts in one operation. The lower welding head must be adapted to varying degrees of adjustment. Generally, the ultrasonic welding head should be made of titanium alloy or alloy steel.

Ultrasonic implantation is the process of embedding metal parts into thermoplastic parts through ultrasonic waves. The size of the embedded hole needs to be slightly smaller than the size of the embedded object, and the embedded hole needs to be designed with a certain angle of interference to provide a guiding effect for the embedded object. The outer surface of the metal insert is usually designed with tooth patterns to enhance the tensile strength of the insert.
Ultrasonic vibration contacts the metal insert through the welding head, so that the heat is transferred to the embedded hole of the plastic part, causing the part of the plastic that interferes with the embedded hole to melt and flow into the bottom of the embedded hole and the teeth of the embedded object. After curing, the metal insert is fixed in the insert hole of the plastic part (Figure 3).
Ultrasonic embedding is not limited by the type of insert. Many other types of applications, such as: hinges for eye frames, machine screws, screws, metal gaskets, metal inner shells of lipstick tubes, round pins, metal shafts, metal meshes, metal screens, and so on.
