1. Principle Ultrasonic metal welding machine uses high-frequency vibration waves to transmit to two metal surfaces to be welded. Under pressure, the two metal surfaces rub against each other to form a fusion between molecular layers. Its advantages are fast speed, energy saving, high fusion strength, good electrical conductivity, no sparks, and close to cold working; the disadvantage is that the ...

1. Welding method: The welding head vibrating with ultrasonic ultra-high frequency under moderate pressure makes the joint surface of the two plastics generate frictional heat and instantaneously melt and join. The welding strength is comparable to that of the main body. Suitable workpieces and reasonable interfaces are used. The design can be watertight and airtight, and avoid the inconvenience c...

When ultrasonic waves act on the thermoplastic plastic contact surface, it will produce tens of thousands of high-frequency vibrations per second. This kind of high-frequency vibration with a certain amplitude will transmit the ultrasonic energy to the welding area through the upper weldment. Because the welding area is two The acoustic resistance at the welding interface is large, so local high t...

Ultrasonic cutting is a kind of ultrasonic equipment specially used for cutting, and it is one of the important categories of ultrasonic applications. Ultrasonic cutting, through the action of ultrasonic waves, causes the grinding wheel blade to generate instantaneous telescopic vibration in the radial direction, which can cause repeated collisions between abrasive grains and processed objects und...

When the partial pressure in the liquid decreases, the process of the formation, development and collapse of vapor or gas cavities (cavitations) inside the liquid or at the liquid-solid interface is called cavitation. Cavitation is a phenomenon peculiar to liquids, which occurs in the low pressure area inside the liquid, especially at the interface between the liquid and the solid. Cavitation in t...

Power refers to the amount of work done by an object in a unit of time, that is, power is a physical quantity that describes the speed of work. The amount of work is constant, and the shorter the time, the greater the power value. The formula for finding power is: power = work/time. Power is a physical quantity that characterizes the speed of work. The work done per unit time is called power, deno...
