Ultrasonic Plastic Welding Machine-IGBT KWD

Features:

KWD0930/0935

Automatic Tuning Frequency Control.
Resonance Frequency Compensation in loading could increase welding capability.
Full-Bridge IGBT power control.
PWM (Pulse Width Modulation) amplitude control, linear adjustment from 50%-100%.
PWM ramp could protect Sonotrode (horn) as it helps to prevent sonotrode shaking when ultrasonic starts activating.
9 selective settings of ultrasonic activation could meet various designed sonotrodes.
LCD displays percentage of amplitude & frequency and easy & clear settings.
Ultrasonic frequency fluctuation & high voltage overload protection.
Frequency compensation at working temperature increase.
Start-up automatic frequency self-checking.

KWD2200/2615

Automatic frequency control, no need to adjust the horn's resonance.
Special circuit design, resonance frequency compensation when loaded to improve welding ability.
Full bridge IGBT modules are used in the generator to improve durability.
PWM (Pulse Width Modulation) amplitude control, linear adjustment from 50%-100%.
PWM controls vibration during start-up to prevent horn damage due to high voltage starts.
8 selective start-up settings for ultrasonic activation to match various horn design requirements.
Ultrasonic frequency fluctuation and high-voltage and overload protection.
Automatic frequency control technology, helps to avoid an increase in horn temperature which could lead to frequency offsets, and affect the welding quality.
LCD displays the ultrasonic frequency and percentage of amplitude, making set up easy and clear.
Control panel uses push button settings and LCD display for welding parameters.
Two welding modes : time control / pressure trigger.
Horn moves using precision linear guides to ensure stability of the welding head.
Lower Horn position adjustment is made by micrometer adjustment .
Two lowering speed adjustments control the Horn downward speed from fast to slow, improving the welding stability.
Start-up automatic frequency self-checking is standard.
