• 28K Desktop Easy Use Ultrasonic Spot Welder For Sports Shoes Basketball Shoes WeldingThe welding precept of ultrasonic spot welder is to convert 50/60 Hz recent into 15, 20, 30 or forty kHz electrical energy via an ultrasonic generator. The switched over high-frequency electric energy is again converted into mechanical movement of an analogous frequency during the transducer, after which the mechanical motion is transmitted to the welding head through means of a set of amplitude modulator instruments that will replace the amplitude. The welding head transfers the acquired vibration energy to the joint of the workpiece to be welded. In this area, the vibration calories is converted into heat energy via friction to soften the plastic. The brief strain maintained on the workpiece after the vibration stops causes the 2 weldments to solidify into one physique in a molecular link. Generally, the welding time is less than 1 second, and the obtained welding strength is comparable to that of the foremost body. Ultrasound can be used not just to weld challenging thermoplastics, but in addition to task materials and films. The leading elements of an ultrasonic welding elements embody ultrasonic generator, transducer/amplitude modulator/welding head triple group, mildew and frame welding principle:Hand-held ultrasonic welding machine, a number of commonly out there operating frequency, 20KHz, 28KHz, 30KHz, 36KHz, 40KHz. The principle is the use of sound waves reached the height function of the gap between the plastic, in the case of pressure, in order that the 2 fusible aspects which might be part of the plastic components in contact with one another to offer the high-speed friction melts, the touch floor of the plastic fusion, obtain the purpose of processing. Machine Features: 1. Hand-held design, welding convenient, compact machine design, small size does not occupy space. 2. Frequency: 28KHz. 3. Slight noise, paintings environmental, no pollution. 4. Welding fast, every single welding time zero seconds. 5. High welding quality, wonderful welding results. Applications: 1. Suitable for spot welding item Φ1-15mm. 2. Suitable for riveting, welding, dots, folder location. 3. For the SD card, U disk, cellular phone antennas, headsets and different communications products, and microelectronics.
