Ultrasonic Spot Welding
Ultrasonic metal welding machine uses the principle of ultrasonic high-frequency vibration and friction to convert the energy of ultrasonic vibration into frictional energy and transfer it to the metal surface to be welded. When the friction generates heat and pressure is applied to it, the metal structure molecules are fully activated. A novel device for forming fusions between molecular layers.
Features: Microcomputer control, electronic tuning frequency, LCD display, continuously adjustable power, simple operation, stable and reliable work; firm welding, good consistency, weldment has the characteristics of firm welding surface, high strength, beautiful appearance, environmental protection and so on.
Easy to operate, built-in electronic protection circuit, safe to use, used for the same type of metal welding, can perform single-point or multi-point welding of non-ferrous metals; widely used in battery and hardware products industry.
Using ultrasonic mechanical vibration, the heat generated by the friction of the processed product can make the plastic reach its own melting point and become a molten state and then apply a certain pressure to combine. There are two kinds of 15,000 times (15KHZ), and there are also several special vibration frequencies. Due to the limited space, only two more common welding types, 15KHZ and 20KHZ, are introduced. And according to its method, it can be divided into two kinds of welding methods: direct and conductive. Direct welding: that is, first make materials such as lines or belts overlap each other (for example: riveting, implantation, etc.), and fix the fixture on the plastic welding machine, so that the energy converter (HORN) directly generates the sound wave vibration effect on it and welds . Conductive welding: that is, when welding, it is separated from the ultrasonic vibration at a distance, and the sonic vibration is used to conduct welding (for example: plastic shell welding, etc.).
A. Thermoplastic plastics other than Teflon can be welded.
B. The welding time is extremely short, usually ranging from 0.05 seconds to 1 second.
C. It can be welded to the joint surface through media such as water, oil, etc.
D. The welding effect can reach the practical level.
E. Direct and conductive welding can be done.
F. Material welding energy surface varies due to plastic materials, and not all materials of ultrasonic vibration, only select a suitable vibration heat source, so that there is no concern of scars on the surface of the product, this is the characteristic of conduction welding. When the hard plastic is welded, it can play its welding effect better.
G. Ultrasonic welding will not produce toxicity such as chemical agents, and it is a safe welding process.
