Where is ultrasonic welding used?
Sonics offers a complete line of specialized ultrasonic equipment
and components for face mask and other PPE textile applications
such as continuous bonding or slitting; punching; plunge bonding;
and hook and loop (Velcro) bonding. Using ultrasonics for these
processes provides superior performance in terms of speed, safety,
cost-effectiveness and smoothness of finished edges. Applications
include face masks, surgical gowns, protective face shields and
many others.
Sonics manufactures a comprehensive range of medical-device capable
plastics welding equipment, tooling and components, from hand-held
units to bench model presses to ultrasonic kits for OEM
installation. Ultrasonic plastic welders, including ElectroPress
welding systems with superior precision control, staking/inserting
machines, and custom tooling and fixtures are available.
Principle of ultrasonic welding generator:
An ultrasonic welding generator is for generating and supplying
ultrasonic energy to an ultrasonic transducer. The purpose is to
convert our city power (220V or 110V, 50Hz or 60Hz) into a
high-frequency AC signal that can be matched with an ultrasonic
transducer. This signal can be a sinusoidal signal or a pulse
signal.
The perfect ultrasonic generator has a feedback link, which mainly
provides the following two aspects of feedback signals.
Output Power signal:
When the input voltage of the ultrasonic generator changes, the
output power of the generator also changes. Will make the
mechanical vibration of the ultrasonic transducer unstable,
resulting in poor working results. Therefore, the output power
needs to be stabilized, and the power amplifier is adjusted
accordingly through the power feedback signal, so that the power
amplification is stable.
Frequency tracking signal:
When the transducer works at the resonance frequency, it has the
highest efficiency and the most stable operation.
The resonant frequency of the transducer will change due to
assembly and work aging. If the changed frequency is only drifting
and not much changed, the frequency tracking signal can control the
signal generator, so that the frequency of the signal generator can
track the resonant frequency of the transducer within a certain
range, so that the generator works in the best state.
