Rinco Ultrasonic Welding Converter C20-12 1421 20kHz

The Transducer

The transducer changes the applied ‘vibrating’ electrical signal into a mechanical vibration. This is achieved by use of a sintered ceramic PZT (lead-zirconate-titanate) material which produces a change in thickness when a change in electrical polarisation is applied. The change in thickness is very small, in the order of 1-3?m. To produce a movement large enough to be of use in the welding operation a number of discs of PZT are used in one converter. PZT materials are exceptionally efficient in converting electrical energy into mechanical vibration, typically more than 95%. This enables the heat increase in the converter to be kept to a minimum.

Early ultrasonic welding machines were developed using metals that exhibit a change in length with changes in polarisation. These types of materials are known as magnetostrictive. Due to their much lower efficiency in converting energy virtually all ultrasonic equipment now uses PZT materials.

All the transducers, we can customize depending on your requirement.

We develop multiple ultrasonic tools, such as:

• Converters 20,30,35, 40 KhZ, built in special aluminium and titanium alloy;
• Boosters 1/1 ,1/1.5, 1 /2,1/ 2.5 etc. available in alloys of aluminium and titanium;
• Sonotrodes 20,30,35,40 KhZ, they can be made in titanium, aluminium and tempered steel.
