Steel Ultrasonic Welding Horn Different Type For Ultrasonic Welding Machine
Our Welding Horn Characteristics:
Ultrasonic welding head (horn) is a general term for all ultrasonic transmitting ends, and is an indispensable part of ultrasonic welding equipment. Its role is to couple the ultrasonic wave generated by the transducer to the processed object. Because it transmits ultrasonic waves, the welding head must work in a resonance state, that is, its natural resonance frequency must match the transducer. Secondly, the amplitude should be uniform, and the shape of the end face of the welding head should be adapted to the shape of the workpiece to be welded.
Selection of ultrasonic welding head material (titanium alloy, magnesium aluminum alloy, powder metallurgy steel, etc.)
Welding Horn and Accessories:
We use high quality imported alloy steel to manufacture the top level welding horn, sonotrode, tip and anvil in the world.Whether you are our equipment users, or European and American import equipment users, we are able to provide high-quality, cost-effective parts services
Advantages:
● Welding materials do not melt, do not destroy metal properties
● Good conduction and thermal conduction after welding, low or almost zero resistance coefficient
● Low requirements for metal surface, oxidation or electroplating material can also be welded
● Short soldering time, no flux, gas, solder required
● It is easy to realize the connection and automatic control between different metals,
No spark while welding, environmental protection and safety
Condition of Ultrasonic Welding:
Ultrasonic automotive plastics as the condition of ultrasonic welding, the most important is the time to apply welding energy (vibration, welding time) length and pressure, of course, other conditions are also very important. Welding temperature ultrasonic welding material viscosity flow temperature. Otherwise the material will not melt.
With the amplitude, the higher the amplitude, the higher the temperature rise. The pressure is applied to the molded article using a cylindrical gaze. General compressed air pressure is 0.1-0.Pa (pressure gauge), sometimes higher. But if the use of high pressure, it will hinder the cylindrical vibration.
The welding time varies depending on the material and the shape of the product. The welding time of some molded articles is only 0.2 seconds. Over time will cause excessive welding and produce a lot of flash and bubble, resulting in poor airtight, must pay attention. Cooling (holding) time For crystalline plastic, if the temperature below the melting point, the connection will be solidified, usually the pressure time is maintained between 0.1-0.2 seconds.
