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.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. AMMA plastic).
