Full kit sonotrode 15khz + transducer + generator for the mask
shape and for the nose fixator
Our Welding Horn Characteristics:
The ultrasonic horn is a circular ring-shaped or similar circular
ring-shaped ultrasonic radiation head. The ultrasonic tool head has
at least a first circular curved surface that radiates ultrasonic
waves by means of bending vibration. The utility model replaces a
single flat radiating surface with a radiating curved surface
having curvature, which greatly increases the radiating area of the
tool head; meanwhile, the radiating surface of the ring-shaped or
similar ring-shaped tool head adopts a ring-shaped radial
radiation. Therefore, the uniformity of the sound field in liquid
or gas is better; again, the radiating curved surface adopts the
bending vibration method, which changes the transmission direction
of the vibration, makes the radiated sound intensity more uniform,
improves the flexibility of the tool head, and can be applied to
some Ultrasonic welding with a cross-section similar to a circular
surface can also be used as a horn.
Feature:
1. The ultrasound system is divided into three parts, an ultrasound
generator, an ultrasound transducer and an ultrasound mold. These
three parts are a complete ultrasound system.
2. Ultrasonic generator is also part of the generation of
ultrasonic energy
3. Equipped with a high-power ultrasonic transducer with a titanium
alloy ultrasonic die head.
4. The machine has low failure rate, wearing parts, durable,
convenient installation and debugging, and simple maintenance.
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).
