20khz Welding Horn 110*20mm For Surgical Face Mask Machine Automatic

20khz Welding Horn 110*20mm For Surgical Face Mask Machine Automatic

Our Welding Horn Characteristics

Special ultrasonic system for mask machine The ultrasonic vibration system can output ultrasonic vibration energy, which can be used for a variety of applications; the system needs to cooperate with mechanical units such as motion and pressure to complete the welding task; with fixed flanges, simple installation; external switches when the system works The signal triggers this system. The system completes a welding process according to a preset time. The program control circuit is provided with delay time, welding time, pressure holding time, and demolding time. The time adjustment accuracy is 0.01s. It can work intermittently. Can also work continuously

Features:

1.With short circuit protection function;

2.Over-current and over-voltage protection, in addition to setting the protection current when tuning the machine, and set the working protection current to prevent damage to the machine caused by excessive current or unstable voltage;

3.The case is fully enclosed, with anti-corrosion and dust-proof function

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 0.1-0.3MPa (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.
