We provide a wide range of high quality ultrasonic transducer, No matter what kind of transducer you are looking for,We can make sure that you can find one at here. it is by utilizing piezo-electric effect to convert electrical energy into mechanical energy. The bolt-on type can make sure that the transducer can produce stable ultrasonic when load changes.
Apply for ABS, PE, PC, PS, PVC, PP, complex Acrylic etc. materials.
Ultrasonic transducer,ultrasonic generator and ultrasonic horn constitute a whole ultrasonic system,which can be widely used to automobile industry, electric industry, medical industry, household appliance industry, non woven fabric clothing, packing, office supplies, toys, etc.
(1) High performance,High quality, high frequency.
(2) Excellent heat-resistance property.
(3) Imported piezoelectric ceramic chips
(4) High amplitude.
The transducer, also known as the converter, converts the electrical energy from the generator to the mechanical vibrations used for the welding process. It consists of a number of piezo-electric ceramic discs sandwiched between two metal blocks, usually titanium.
Between each of the discs there is a thin metal plate, which forms the electrode. As the sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing an axial, peak-to-peak movement of 15 to 20μm.
Transducers are delicate devices and should be handled with care. Once the elements are broken, the transducer will not function.
The booster section of the welding stack serves two purposes, primarily to amplify the mechanical vibrations produced at the tip of the transducer and transfer them to the welding horn. Its secondary purpose is to provide a location for mounting the stack on the welding press.
The booster expands and contracts as the transducer applies the ultrasonic energy.
The booster, like other elements in the welding stack, is a tuned device therefore it must resonate at a specific frequency in order to transfer the ultrasonic energy from the transducer to the welding horn. In order to function successfully, the booster must be either one half of a wavelength of ultrasound in the material from which it is manufactured, or multiples of this length. Normally, it is one half wave length.
Welding of plastic using ultrasonic
Ultrasonic welding of plastic materials creates a molecular bond within the weld seam. Longitudinal vibrations in frequencies of 20 kHz, 30 kHz, and 35 kHz with tool amplitudes between 5 μm and 50 μm are introduced into the plastic materials under the action of force. Ultrasonic vibrations are focused by means of special design of the components or tools. This specific geometry within a component is referred to as energy director. The contact points in the joining area are actively molded by means of energy input to achieve elastic deformation. Friction occurring between the contact surfaces and within the molecule chains generates heat that causes the material to melt.
Applicable all industry
Widely used in the automotive industry, electronic industry, medical industry, household appliances, woven apparel, office supplies, packaging industry, toy industry and so on.
Highest weld quality: Vehicle parts must be joined to be tight, strong, dimensionally accurate and visually impeccable. Ultrsonic welding is a fast and economic solution for this complex task.
Hygiene industry : Laminating of nonwoven materials using ultrasonics
The general principle of ultrasonic welding can also be applied to nonwoven materials. The thermoplastic fibers are activated by mechanical vibrations thus melting and bonding in pre-defined patterns. A weld tool, referred to as Sonotrode, transmits the vibration into the nonwoven material. In industrial applications, ultrasonic frequencies between 20 and 35 kHz are common, with amplitudes (tool travel distances) of 10 μm to 50 μm. Processing of nonwoven materials is often performed in continuous processes at high web speed. By application of rotary tools, it is possible to achieve processing speeds of up to 800 meters/minute. A specifically engraved drum is used as welding, embossing, or cutting anvil. The contour of the anvil drum focuses the energy and precisely defines the weld spots required for the respective product.
