100*20mm 20k Ultrasonic Transdcer +Welding Horn For 3 Layer Mask Machine

Our Welding Horn Characteristics

The main function of the ultrasonic horn is to transmit ultrasonic vibration to the workpiece to be processed. Its material is usually aluminum alloy and titanium alloy. When ultrasonic waves are transmitted through the tool head, tool head defects made of defective or cracked materials are likely to expand with vibration and shorten the life. The two types of materials here have better homogeneity of the metal base material and can withstand long-term and repeated vibration.

Application:

Medical mask, surgical gown non-woven bag making machine, non-woven surgical cap making machine, non-woven fluffy cap making machine, non-woven shoe cover making machine, non-woven ultrasonic welding machine, ultrasonic lace machine, three-layer bag making machine , Plastic bag making machine, stationery, machinery, automation equipment, etc.

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.
