35kHz 1000W Handheld Ultrasonic Assembly for Silencer in Auto Parts

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:

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:

Advantages:

Ultrasonic welding offers many advantages to assemblers. It is a fast, efficient, flexible process that offers quick tooling changeover. No warm up or cool down time is necessary, unlike other welding processes, such as hot-plate welding. Ultrasonic welding is an energy efficient cold-working process that does not require elaborate ventilation.

Unlike other joining processes, such as resistance welding, ultrasonic welding does not generate excessive heat that could damage components. The energy efficiency of ultrasonic welding technology appeals to manufacturers that are searching for ways to cut production costs.
