How Ultrasonic Assembly Is Done
Ultrasonic assembly is accomplished by converting high frequency electrical energy into high frequency mechanical motion. That me- chanical motion, along with applied force, creates frictional heat at the plastic components' mating surfaces (joint area) so the plastic material will melt and form a molecular bond between the parts. Standard 50 or 60 Hertz AC line voltage is supplied to the generator (power supply) and converted to 15,000 or 30,000 Hertz (i.e., 15 kHz or 30 kHz) AC electrical energy. This high frequency electri- cal energy is connected to a piezoelectric transducer (converter), which changes the electrical energy into mechanical vibrations. These vibrations, when applied to a part under force, will create frictional heat and cause the plastic to melt at the joint area. As the plastic cools, a homogeneous molecular bond is formed between the components.
Ultrasonic Bonding
Ultrasonic bonding assembles two or more layers of nonwoven materials by passing them between a vibrating horn and a rotary drum (often referred to as an anvil ). The rotary drum is usually made out of steel and has a pattern of raised areas machined into it.
The high frequency mechanical motion of the vibrating horn and the compressive force between the horn and the rotary drum create frictional heat at the point where the horn contacts the material(s), bonding the material(s) together in the pattern of the rotary drum. Bonding takes place only at the horn/material contact points, which gives the bonded material(s) a high degree of softness, breathability, and absorption. These properties are especially critical for hospital gowns, sterile garments, diapers, and other applications used in medical industry and clean room environments.
Ultrasonic bonding uses much less energy than thermal bonding, which uses heated rotary drums to bond material(s) together. As with other ultrasonic assembly techniques, ultrasonic bonding requires no consumables, adhesives, or mechanical fasteners.
