40kHz High Power Handheld Ultrasonic Welding Device

 


Specification:

 

Description:

Ultrasonic welding is a form of friction welding that joins parts together by vibrating them against each other. The parts are clamped together while a vibrating tool called a horn transfers ultrasonic energy to the joint interface. Heat is generated through a combination of friction and hysteresis. Amplitudes of 20 to 80 microns are usually produced at the end of the horn. When the ultrasonic vibrations stop, the molten material solidifies and a weld is achieved.

 

Important factors:

The welding time and the welding head pressure can be adjusted with the amplitude determined by configuration of the converters and rods. Generally, the main variables are:

Amplitude rods and converters

Welding head pressure

Welding time

Hold time

The adjustment must be precise. If the frequency is too high or the amount of time the signal is applied is too long, the plastics can easily deform outside of the boundaries of the connection points. If the applied energy is too weak, then a poor connection forms.

 

Type of Horn:

 

Application:

Ultrasonic plastic welding is suitable for virtually all thermoplastics. When planning welds between semi-crystalline plastic pieces of work, it is important to remember that the weld behaviour of these plastics differs considerably from that of amorphous plastics.

Ultrasonic plastic welding can be used to a limited extent for joining together two different thermoplastics (amorphous plastics). Ultrasonic welding is not suitable for use with thermo setting plastics. Today ultrasonic welding is used in every industry that processes plastics. Most common uses are in the Automotive, Medical, Textile, Food, Plastics, and Packaging industries.
