15k 20k Ultrasonic Spot Welding Machine For Non Woven Face Mask Machine

Our Welding Horn Characteristics:

Different ultrasonic applications and welding materials have different welding sizes and specifications, and different specifications are required for different welding objects. Whether it is near-field welding or transmission welding, only half-wavelength tool heads can Make the welding end face reach the maximum amplitude. Tool heads are available with and without amplitude amplification.

Features:

1. Intelligent ultrasonic generator, digital circuit design, automatic scanning frequency, no manual adjustment required;

2. LCD display of frequency, power and current, ultrasonic amplitude adjustable from 50% to 100%;

3. The ultrasonic transducer is assembled by Japanese original piezoelectric ceramic chip, which has strong and reliable power.

4. The system is equipped with multiple detection and protection circuits. When the output cable is open, the transducer and the mold exceed the frequency range, etc., the overload protection circuit automatically cuts off the ultrasonic power and alarms;

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.
