Transmitted ultrasonic energy through welding parts to welding area, local high temperature will happen due to high acoustic resistance between two welding interface places with a certain pressure, it makes fusion to one unite. When ultrasonic stop function, and keep the pressure sustain to make its solidification molding, finally forming a strong molecular chain, which achieve the purpose of welding.

Two Types of Horn

Gun type: in accordance with the shape design of human body engineering, ultrasonic start switch is located on the trigger, easy to grasp and use the welding operation, especially suitable for horizontal or vertical.

Cylinder type: for the appearance of design straight, ultrasonic start switch is located outside the cylinder, easy welding and hand carried, can also be installed between the on machine, welding operation for each direction.

Principle of Ultrasonic Car Bumper Riveting Spot Welder

When the ultrasonic role in the thermoplastic plastic contact surface, it will generate tens of thousands of times per second, high frequency vibration, this high-frequency vibration, ultrasonic energy through the ultrasonic wave transmitted to the mold to ultrasonic welding material surface, it will produce high-temperature materials. Plastic contact surface resulting in rapid melting, coupled with stress, it blend and coagulation, so that to achieve the purpose of ultrasonic welding.

Types of Ultrasonic Welding

Ultrasonic welding: ultrasonic vibration with ultrasonic welding mould, the ultrasonic welding energy conduction to the plastic surface, resulting in local temperature, so that the plastic surface melting. Under the pressure of the ultrasonic hand, so to weld plastic, beautiful, strong effect.

Ultrasonic implants: the nut screws or other metal into plastic work piece. Ultrasonic energy through the ultrasound machine will be transmitted to the metal. The high-speed vibration and heat, the pressure in the ultrasound machine to make metal objects embedded directly into the plastic inside.

Ultrasonic riveting: the nature of metal and plastic or two different plastic bonding together, can make use of ultrasonic riveting machine, so that the weldment hard brittle, beautiful, strong.
