Welding method: It is a welding head that vibrates at an ultra-high frequency of ultrasonic waves under a proper amount of pressure, so that the joint surface of the two plastics generates a frictional heat to instantaneously produce a fusion joint, and the strength of the welding can be comparable to that of the body, using Appropriate workpieces and a reasonable interface design can achieve watertightness and airtightness, and eliminate the inconvenience caused by the use of auxiliary materials, thus achieving efficient and clean welding.
The rivet welding method: a welding head that ultrasonically vibrates at a high frequency, presses the tip of the plastic product, so that the instant heat is melted into the shape of the rivet, so that the materials of different materials are mechanically riveted together.
Embedding: By means of the trajectory of the welding head and appropriate pressure, the metal parts (such as nuts and screws) are squeezed into the plastic hole and fixed to a certain depth. After the completion, the tension and the torque can be completed. Comparing the strength of the traditional mold, it can eliminate some of the shortcomings of the injection mold damage and slow injection.
Molding: This method is similar to the rivet welding method. The concave welding head is pressed against the outer ring of the plastic product, and the ultrasonic welding of the ultrasonic hair after the ultra-high frequency vibration is applied to the metal object to make it fixed. Moreover, the appearance is relatively smooth and beautiful, and this method is often used in the fixed forming of electronic types and speakers, and the fixing of lenses for cosmetics.
