Plastic Welding by Ultrasonic Welding Machine with Generator Transduce, Ultrasonic Welding Generator, Ultrasonic Generator Welder

Working Principle
4200W ultrasonic plastic welding machine is a new developed machine.it processes plastic spare parts by ultrasonic plastic welding principle.its advantages are strong power,time-saving, sensitive response, feedback spring pressure mode, and can avoid 20% friction resistance variable of cylinder and greatly increase production capacity.with high speed,high efficiency and clean.
High pressure and frequency 15KHZ electric signal produced by ultrasonic generator come though transducer and is converted into same frequency mechanical vibration by Inverse piezoelectric effect.then acts on the plastic parts in the form of audio longitudinal wave,which increases the temperature transmitted to the interface through the friction between the surface of the work piece and the internal molecules, When temperature reaches the melting point of the work piece,its interface will melt rapidly, and then fill the gap between the interfaces. When the vibration stops, the work piece will be cooled and fixed under certain pressure to achieve perfect welding.


Welding characteristics

• Important electronic elements use perfect original imported brand
• New type single support can adjust height of main body.with manual and automatic type,easy to operate.
• Huge platform,stable mechanical properties,applied in varies of welding workshop.
• With automatic overload protective circuit,improve product life and safety.
• Imported booster,longer life,with High temperature hot-dip baking paint treatment on surface,strong corrosion resistance.
• Use most advanced time-welding,deep-welding welding style etc.it's more suitable for high precision welding

FAQ
Compared with other welding methods, ultrasonic welding can accept thermoplastic materials. It has many advantages, including process reliability and repeatability, lower energy use than other bonding technologies, saving materials and corresponding labor costs. What are the common problems in ultrasonic welding? What are the specific aspects?

Ultrasonic problem : abnormal heating of ultrasonic mold

When the ultrasonic mold is working, there will be a certain heating phenomenon, which is caused by the mechanical energy loss of the material itself and the heat conduction of ultrasonic objects. Whether the heating of ultrasonic mold is normal or not is judged as: when the ultrasonic mold is not loaded (i.e. not contacting the workpiece), the ultrasonic wave is continuously emitted for more than half an hour, and the temperature should not exceed 50-70 ºC. If the heat is damaged, it is proved that the ultrasonic mold has been damaged or the material is unqualified and needs to be replaced; if the mold temperature is too high, it is usually accompanied by abnormal high ultrasonic current;
