Ultrasonic welding is often used in packaging applications. Many common items are either created or packaged using ultrasonic welding. Sealing containers, tubes and blister packs are common applications. Ultrasonic welding is also applied in the packaging of dangerous materials, such as explosives, fireworks and other reactive chemicals.
Ultrasonic energy is then applied to create a weld. After the weld is cooled down, the parts are removed from the fixture. At the start of the process, an actuator is moved to a part. This stage is called downstroke. [3] Ultrasonic energy can be applied during this phase depending on the size of a horn used.
In ultrasonic welding, high frequency (15 kHz to 40 kHz) low amplitude vibration is used to create heat by way of friction between the materials to be joined. The interface of the two parts is specially designed to concentrate the energy for the maximum weld strength. Ultrasonic can be used on almost all plastic material.
Parts cleaning is a step in various industrial processes, either as preparation for surface finishing or to safeguard delicate components. One such process, electroplating , is particularly sensitive to part cleanliness, as even thin layers of oil can hinder coating adhesion .
Ultrasonic cleaning is a process that uses ultrasound (usually from 20 to 40 kHz) to agitate a fluid, with a cleaning effect. Ultrasonic cleaners come in a variety of sizes, from small desktop units with an internal volume of less than 0.5 litres (0.13 US gal), to large industrial units with volumes approaching 1,000 litres (260 US gal).
Rotating sonotrode during ultrasonic welding of thin metallic foils. In ultrasonic machining, welding and mixing, a sonotrode is a tool that creates ultrasonic vibrations and applies this vibrational energy to a gas, liquid, solid or tissue. A sonotrode usually consists of a stack of piezoelectric transducers attached to a tapering metal rod ...
