With the development of the times, the application of ultrasonic welding is becoming more and more widespread, it has the advantages of low energy consumption, low pressure, high speed, high stability, simple procedures, etc., then. Do you know the ultrasonic plastic welding a total of several welding methods?

　　1. fusion method: ultrasonic vibration with the welding head will be ultrasonic conduction to the weld, due to the two welded parts at the acoustic resistance is therefore generated locally high temperature parts cross-interface melting. Under a certain pressure, so that the two welded parts to achieve beautiful, fast, solid fusion effect.

　　2. Embedding method: nuts or other metals want to insert plastic workpiece. First of all, ultrasonic waves will be transmitted to the metal, by high-speed vibration, so that the metal object directly buried in the molding plastic, while melting the plastic, its curing after the completion of the buried insert.

　　3. riveting method: want to metal and plastic or two different nature of the plastic joint, can use ultrasonic riveting method, so that the welded parts are not easy to brittle, beautiful, strong.

　　4. spot welding method: the use of small welding head will be two large plastic products point welding, or the whole row of tooth-shaped welding head directly pressed on the two plastic workpiece, so as to achieve the effect of spot welding.

　　5. Forming method: Using ultrasonic waves to melt and form the plastic workpiece instantly, when the plastic solidifies it can make the metal or other materials firmly.

　　6. Excision method: Using the special design of the welding head and base way, when the plastic workpiece is just shot, directly pressed on the branch of plastic, through the ultrasonic conduction to achieve the effect of excision.

　　Ultrasonic welding is a fast, clean and effective assembly process, used to meet the requirements of high-strength assembly of plastic parts, is a widely used advanced assembly technology, suitable for many types of plastic parts assembly, coupled with its energy-saving, environmental protection, easy to operate and other outstanding advantages, for China's construction of resource-saving, environmentally friendly modern society, ultrasonic plastic welding will play a great role in promoting.
