Impressively-rebuilt ultrasonic converters

How it Works

So how exactly does ultrasonics work? When power is introduced to the converter, electrical energy is converted to mechanical movement. The electrical charge goes across the surface of the ceramics at the operating frequency of your system and that results in movement or vibration at the output end of the converter.

If converter is threaded onto a booster, the booster will increase, decrease or transfer the amount of movement from the face of the converter to the horn.

When the horn contacts the part it will vibrate for a few milliseconds under a preset pressure. It will continue to apply pressure for a few milliseconds once the vibration has stopped. This is also known as the weld and hold time. These vary depending on the configuration of the part being welded and the type of plastic being welded. Welding can also be controlled by distance and energy.

Additional power is needed from the power supply, (generator) when a larger horn is used. In this case, more stress is then placed on the converter.

You can always contact us if you have a question about power or amplitude required to successfully accomplish your weld.

Ultrasonic Converter Tech, (USCT) rebuilds converters of all types such as Dukane, Branson, Sonic and Materials & Herrmann, among others. USCT can provide a cost saving converter for any manufacturers’ ultrasonic welder.All converters USCT rebuilds come with a full 2 year warranty. When we rebuild your converter, we replace all components. The only item we don’t replace is the can, which houses all the internal parts.

Once the driver is built, the ceramics are left to age for an extended period to stabilize before being charged with electrical current. USCT then puts the converter through rigorous testing. These tests include: mounting the converter to a high gain horn and booster letting it run continuously. Then recording actual performance parameters. Prior to shipping every converter, USCT records all critical measurements taken from each converter. This allows us to track the efficiency of each and every converter.

At Ultrasonic Converter Tech, we offer our customers both new and rebuilt converters.

All our new converters come with a full 3 year warranty. This all inclusive warranty includes new front and back mass, ceramics, wafers, all housed in a new can with or without a new cable, if required.

Many of our customers purchase new converters.

Our replacement converters are manufactured to meet and/or exceed OEM specifications. The converters sit on our shelf during an aging process to ensure they are at its optimum efficiency for performance. We test them prior to shipping and record all test parameters. The different parameters we incorporate in our testing include frequency in air and under load, impedance, square wave with node and anti node readings.
