UltraSonic Converter Tech

Impressively-rebuilt ultrasonic converters


The purpose of rebuilding converters is to save you money when compared to buying a brand-new one instead. With that in mind, USCT doesn’t just go right into offering you rebuilt ultrasonic converters when you reach out to us.

When you send your converter to USCT, we will perform a free physical examination and test to find out exactly why your converter failed. Through these tests and examinations, we can determine if it was, in fact, the converter that caused your problems or not. Sometimes, we find that it is not the converter at all, but rather something else in the welder causing the problem—such as a failed horn or bad amplitude control board.

Once we know the cause of your problem, we can then begin to offer you the solutions you actually need so you don’t have to waste any money getting your system back into working order.

Rebuilt rebuilding dukane & branson ultrasonic converters

The main component of a converter, no matter the manufacturer, is known as the driver. The driver includes 4-6 piezoelectric ceramics in a 20 kHz system and 2-4 ceramics at various other frequencies. These ceramics are separated by stainless steel wafers that distribute positive and negative ground across each ceramic’s surface. They are then matched and measured to meet the highest efficiency.

When you purchase a rebuilt converter from us, you are getting a converter that includes all new parts. All of these internal parts are replaced. The only thing we don’t change out is the canister you returned to us that houses your broken converter. Even better, you get a full 2-year warranty with every rebuilt converter that leaves our factory.

If you don’t have an ultrasonic converter available to be rebuilt, then you may purchase a new one or rebuilt one from us. Contact us to receive a free estimate on your converter, booster, or horn.
