High Power 20KHZ 3200W PZT8 Ultrasonic Welding Booster for N95 Ultrasonic Welding

Ultrasonic waves are transformed into mechanical vibrations through transducers. The characteristics of transducers depend on material selection and manufacturing process. The performance and service life of transducers of the same size and shape are very different. The commonly used high-power ultrasonic transducer is used in ultrasonic plastic welding machine, ultrasonic metal welding machine, various handheld ultrasonic tools, continuous working ultrasonic emulsifier, atomizer, ultrasonic engraving machine and so on. Commonly used products such as 15KHz 20KHz 28KHz 35KHz 40KHz 55KHz 70KHz can also design and produce non-standard transducers according to the special requirements of customers to meet all kinds of needs.

Ultrasonic welding is an industrial technique through which a very high-frequency ultrasonic acoustical vibrations are applied to the work pieces locally and which are being confined together under the influence of high pressure in order to develop a solid-state weld, mostly used for plastics. In other words, it is the joining or altering of thermoplastics via heat which is generated from high-frequency mechanical motion. Electric energy of high frequency is converted into mechanical motion of the same high-frequency to attain welding process. This mechanical motion along with the force which is applied generates frictional heat at the plastic components’ joining surfaces. This will enable the plastic material to melt and form a molecular bond amongst the parts.

Ultrasonic Welding Process

The ultrasonic welder machine will comprise of components such as – Transducer, Sonotrode and Anvil. The complete welding mechanism will include the following steps:

A stationary clamping force is put exactly perpendicular to the interface in between the work pieces.
Then the contacting sonotrode of the welder oscillates parallel to the interface.
This coalesced effect of stationary and oscillating force generates deformation which furthers welding.

Ultrasonic welding transducer; widely used in electronics, electrical appliances, plastics, home appliances, toys, automobiles, packaging, communications, and medical applications. Ultrasonic welding machines are used to weld plastic products, instead of screws, buckles, glue and other pasting solvents, saving materials and welding The final product is firm and the welding efficiency is high. Its advantages are to increase production efficiency by multiple times, reduce costs, and improve product quality.

The welding head vibrating with ultrasonic ultra-high frequency under moderate pressure makes the joint surfaces of the two plastics generate frictional heat and instantly melt and join, and the welding strength is comparable to that of the main body. The use of suitable workpieces and reasonable interface design can achieve water and air tightness, avoid the inconvenience caused by the use of auxiliary products, and realize efficient and clean welding. For all application markets, ultrasonic welding has its unique advantages---fast, efficient, clean and firm.
