• Small Table Ultrasonic Welder Piezoelectric Converter Pzt8 Ceramic Transducer 28K 800WUltrasonic transducer is also known as ultrasonic vibrator, and the entire after connecting the transducer and horn is called vibrator. It is a tool that realizes the mutual conversion between electricity and mechanical calories (acoustic vibration) by means of the piezoelectric effect of piezoelectric ceramics, and is amplified by way of technique of the doorway and rear radiation hide blocks that occasion the acoustic impedance the horn is a passive device, it doesn't produce vibration itself, but transmits the enter vibration after replacing the amplitude, completing the impedance transformation transducers can produce regular vibration beneath the excitation of electrical field, but the amplitude is usually about 10μm. Such amplitude isn't sufficient to immediately total the welding and processing procedures, after the transducer is hooked up to a fairly designed horn, the amplitude of the ultrasonic wave can be replaced in a enormous range. As prolonged as the material calories is sufficient, the amplitude can exceed 100 μm. Ultrasonic transducer composition:1. Middle piezoelectric ceramic element 2. Front and rear metal cover 3. Prestressed screw 4. Electrode sheet 5. Insulating tube form of sandwich transducer generates steady ultrasonic waves when the weight changes, which is a comparatively basic and main strategy to obtain a power ultrasonic energy source to various designs, the foremost varieties of ultrasonic transducers are:1. Column variety 2. Inverted horn sort 3 Steel again hide type 4. Intermediate aluminum sheet kind The ultrasonic transducer conducts ultrasonic waves to the plastic processing elements in the process the welding head, in order that the 2 plastic joints are subjected to ultrasonic waves to produce violent friction, and the friction warm temperature melts the plastic joints to complete the gluing. This expertise has the benefits of rapid speed and firm welding seams, and additional importantly, it'll automate the production and processing of plastic products. Ultrasonic plastic welding machine can perform plastic welding, embedding, forming, riveting, spot welding, cutting, sewing and different operations. As lengthy since the welding head is changed, one machine can be utilized for several applications. Our company makes a speciality of the manufacturing of ultrasonic welding transducers. This product has excessive performance, prolonged life, and nice welding effect. The ultrasonic used in plastic processing, the current operating frequencies are 15KHZ, 18KHZ, 20KHZ, 40KHZ. The precept is to apply the height operate of the longitudinal wave to transmit the amplitude to the distance of the plastic part. Under pressure, the 2 plastics The molecules in the touch elements of the elements or different features and the plastic elements collide with one another to melt, in order that the plastic in the touch operate is fused, and the processing target is achieved. Ultrasonic welding transducer for the ultrasonic processing of thermoplastic glue makes use of the high-frequency friction between the operating joints to quickly generate warmth between molecules. When the warmth is satisfactory to melt the work, the ultrasonic vibration is stopped. At this time, the operating joint The noodles are melted and solidified to finish the processing procedure. The frequencies assuredly used for plastic processing are 20KHZ and 15KHZ, and their frequencies are outside of human hearing, so they are referred to as ultrasonic waves. Ultrasonic welding machines needs to be used in the electronics industry, stationery industry, transportation equipment, toys, cosmetics, motors and different materials comparable to PP, PE, ABS, and acrylic. （External sizes）（Electeomachanical characteristic） SpecificationConnect ScrewCeramic diameter（mm）Quantity of Ceramics（pcs）Resonance Frequency（KHZ）Resistance（Ω） Yellow Ceramic Black Ceramic Input PowerMax Displacement（um）PLS-6015-4C-SiM16*1*1 420011PLS-6015-4C-QuM16*1*1 260011PLS-5020-4C-SiBS3/8504201511500-1200013500-1400015008PLS-5020-4C-SiBS3/8504201519000-21000 20008PLS-5020-4C-TrM16*1 32008PLS-5020-4C-TrM16*1 17500-1800032008PLS-3828-4C-SiBS3/838428158000-8500 10005PLS-3035-4C-SiM8 8004PLS-3040-4C-SiM10*1 8002
