I. General Information
Ultrasonic plastic welder is mainly used for secondary joining of thermoplastics.
Compared with other traditional processes (such as gluing, electric
heat-joining, or screw tightening), it has remarkable advantages like high
productivity, sound welding quality, environmental protection and energy
saving, among others.
Working principle of ultrasonic plastic welder: the welder converts the electric
energy into ultrasonic energy through the ultrasonic transducer (i.e.
high-frequency mechanical vibration energy with the frequency exceeding the
threshold of human’s auditory sense). Conducted to the plastic work piece
through the welding head, such ultrasonic energy melts down the joint face of
the plastic work piece after rubbing the joint face violently with ultrasonic
frequency at the speed of tens of thousands of times per second and with
certain amplitude. The transient pressure maintained at the work piece after
stopping vibration makes two pieces of weldment solidify together in the form
of molecular interlinkage. Generally, the welding time is less than 1 second,
but the weld strength compares favorably with that of a weldment itself.
By adopting electronic program control and built-in full automatic protective
circuit.
KCH series ultrasonic plastic welder has such features as high automation,
easy and safe operation, stable and reliable running, etc.
KCH series ultrasonic plastic welder is applicable for butt welding of
thermoplastics. With its welding head replaceable according to the customers’
requirements, the welder can also be used for processing such as rivet
welding, spot welding, embedding, cutting, etc.
