General method
1. Welding method: Ultrasonic vibration transmits ultrasonic waves to the weldment along with the welding head. Due to the large acoustic resistance of the two weldments, local high temperature is generated, and the weldment interface is melted. Under a certain pressure, the two weldments achieve a beautiful, fast and strong welding effect.
2, implant (insert) method: nut or other metal to insert into the plastic workpiece. First, the ultrasonic wave is transmitted to the metal, and after high-speed vibration, the metal object is directly buried in the molded plastic, and the plastic is melted, and the solidified material is buried.
3. Molding method: The plastic workpiece is instantly melted and formed by ultrasonic waves, and the plastic of metal or other materials can be solidified when the plastic is solidified.
4, the cutting method: the special design of the welding head and the base, when the plastic workpiece just shot, directly pressed on the branches of the plastic, through the ultrasonic conduction to achieve the effect of resection
5, riveting method: To join metal and plastic or two plastics with different properties, ultrasonic riveting method can be used to make the welding parts not easy to be brittle, beautiful and strong.
6. Spot welding method: Two small plastic products are welded by points, or a whole toothed welding head is directly pressed on two plastic parts to achieve the effect of spot welding.
Butt welders are also known as current welders or resistance welders. By using the resistance between the contact surfaces of the two workpieces, the contact surface of the two mutually butted metals is instantaneously heated to melt and fuse by instantaneously passing a low voltage and a large current.
